Mr. Benson in the preceding paper has given an account of the new facts which have been brought to light by the complete clearing of the Thersilion. With regard to these points of fact there can be no question and in the deductions to be drawn from them we are for the most part agreed. It remains to be seen whether from the remains before us we can reconstruct a building of any known Greek design, in other words, whether we can discover what was the builder's plan and how he developed it. At first sight a large columned hall of this nature appears to be un-Greek in character: the only parallel we can produce for it is the late Hall of the Mysteries at Eleusis, which however only resembles it in the badest characteristics. Where we do find halls which resemble this building however is in the East. The Hall of the hundred columns at Persepolis (Perrot et Chipiez, v. p. 723) presents several striking analogies: like the Thersilion it is a large square building on one side flanked by a portico while we have two doors on each of the other three. Now, as is clearly shown by the character of the building, the Thersilion belongs, in its original plan, to the earliest period after the foundation of Megalopolis by Epameinondas. That is sufficiently proved by the cramps and the. use of tufa rather than conglomerate for the foundation bases. Moreover just at this period we have a direct communication between Persia and Megalopolis in the person of Antiochus, who visited Susa as a delegate from the Arcadian league in 367 B.C. (Xen. Hell. vii. 1, 33–38 J.H.S. Supp. Pap. I. p. 128), and it is quite possible, whether he was the dedicator of the theatre thrones or not, that he brought back the idea of such a columned hall from the East. But it can have been only the general idea that was so brought to Megalopolis: the arrangement of the columns in the Thersilion is entirely different from that of its prototypes in the East, while the inward slope of the floor is also a new element. Thus, though this building may have owed its origin and shape to the East, its plan, as I will endeavour to show, is taken from a common Greek type, and is in fact simply that of a Greek theatre.

I have read with interest Doctors Adams' and El-Salawy's comments on my case report identified in their letter as the "Lausanne baby." I do think that the "Lausanne baby" represents a case of pulmonary vascular sequestration inasmuch as the inferior lobe of the left lung received its blood supply by means of three arterial branches coming off directly from the aorta. On the other hand, I do not think that the "Lausanne baby" is a case of pulmonary parenchymal sequestration and this because the inferior lobe of the left lung was proven to be, at least to my satisfaction, in direct communication with the remainder of the respiratory tract.

There is a general idea expressed in text-books, and more or less freely asserted in practice, but which I shall prove to be a fallacy, that a high-arched palate is so frequently met with in idiocy and imbecility that it may be taken as a sign of their existence. Indeed, when a case of this kind is brought forward the patient is made to open his mouth, under the conviction that a high palate will be found as certainly as a superficial alteration of the tongue in gastric disturbance. We shall see that the connection is an accidental one; and there is, in reality, no relationship between the development of the intellect and the height and width of the palate. If we consider that the bones of the cranium are developed in a different manner from those of the face, and that ossification at the base is complete long before that of the bones forming the palate, it is clear that there can be no primâ facie reason for thinking that because a person has an imperfect brain he should therefore have an imperfect palate; yet such an interdependence is held. It is quite true that a constitutional taint, such as rickets or syphilis, which affects the ossification of the bones generally and the cranial sutures, would probably affect the palatine bones, and hence it is that many idiots and imbeciles are found to have high or imperfect palates: but on the other hand some modifying taint may dwarf the height of the body, may affect the shape of the head to such an extent as to make an idiot of the microcephalic type, and yet leave the palate untouched, perfect in all conditions of width, height, number, quality, and regularity of teeth.

Touch can create a feeling of intimacy and connectedness. This work proposes feelabuzz, a system to transmit movements of one mobile phone to the vibration actuator of another one. This is done in a direct, non-abstract way, without the use of pattern recognition techniques in order not to destroy the feel for the other. The tactile channel enables direct communication, i. e. what another person explicitly signals, as well as implicit context communication, the complex movements any activity consists of or even those that are produced by the environment. This paper explores the potential of this approach, presents the mapping use and discusses further possible development beyond the existing prototype to enable a large-scale user study.


1. No systematic investigation on this subject has yet been attempted. The efforts made to group these materials in a series according to the charges generated when they are rubbed two at a time are of uncertain value because of (1) impurities of substance and surface, (2) indeterminate initial surface strains. Moreover, the general practice has been to rub the solids when held, one in each hand. A more reliable method is to mount the bodies in a mechanism which ensures that the same parts of them come into contact at each fresh stroke. In the present research, the elements, mostly metals, are those specified in the preceding paper. The textiles are made and cleansed as described in an earlier paper. Silk, cotton and linen in our experience behave reliably when fully cleaned. The other great textile material, wool, is more oily and cannot be readily cleansed; so is less trustworthy. We therefore at present confine ourselves to one animal and one vegetable textile, choosing the pure samples of silk and cotton specified in the above paper. Also filter paper, another convenient fabric, is used after being boiled in several lots of distilled water. As the silk and cotton are treated with boiling chloroform, we tried exhausting the filter paper in this solvent to see if such treatment affected the cellulose in any way; but no effect on the properties of the paper could be found.

The current study tested when partners’ negative-direct communication promotes perceived commitment and helps preserve relationship quality and when partners’ negative-direct communication damages perceived commitment and relationship quality. Negative-direct communication was assessed within 322 relationship conflict discussions involving one partner (the agent) wanting change in the other (the target). Perceived commitment and relationship quality were repeatedly assessed across the following year. Greater negative-direct communication by partners as agents of change predicted more positive trajectories of perceived partner commitment and relationship quality across time, whereas greater negative-direct communication by partners targeted for change predicted declines in perceived commitment and relationship quality. These longitudinal effects were magnified for people who initially perceived their partner’s commitment to be low. Thus, partners’ negative-direct communication can help sustain relationship quality when it offers a needed sign of partners’ commitment but has detrimental effects when partners’ negative-direct communication reflects low responsiveness to attempts to improve relationship problems.

The Turin manuscript containing the first three books of Oppian' Halieutica was almost completely destroyed in the fire of 1904, but a collation of it has recently come to light. In 1811 the noted classical scholar and Orientalist Vittorio Amedeo Peyron collated the manuscript against Schneider' first edition of the poem (Strasbourg, 1776) and also transcribed the scholia. He sent his results to Schneider for use in the preparation of his second edition (Leipzig, 1813), but they apparently arrived too late. Although the original plan of this second edition called for the inclusion of the scholia, Schneider published only a text of the poem and turned over his materials on the scholia to G. H. Schaefer, including no doubt Peyron' collation of the Turin manuscript. Schaefer never did manage to produce his edition of the scholia and in some unknown way Peyron' collation and some of the other material came on to the open market in 1969.

1. When the few individuals still alive in a dissolved culture of Bacillus coli are transplanted on slanted agar, a culture results which possesses new characteristics. First observed by Bordet and Ciuca, this culture received the temporary name of modified coli. In the study described above, we found that this modified coli is very heterogeneous and that its three principal characteristics, resistance to lysis, lysogenic properties, and mucoid growth, are shared among different types of organisms that can be isolated when the normal original coli (coli O) is plated together with increasing quantities of the lytic agent: (a) a certain number of bacilli are just resistant enough to survive and grow in the presence of a moderate quantity of lytic agent, but they are still more or less sensitive and produce diseased, irregular, and lysogenic colonies; (b) a few of the organisms are able to resist concentrated lytic agent; they are entirely resistant and give round, healthy, and non-lysogenic colonies (coli O R 2); and (c) among these resistant bacilli only a very few are mucoid (coli 0 R 1). All these types are not motile and not fluorescent. 2. The original coli, when allowed to age, can be dissociated, as we have shown in a preceding paper (1), into two types of organisms, the non-motile coli S and the very motile coli R. Submitted to lysis, coli S gives a very small number, coli R a much greater number of resistant organisms (coli S R and coli R R), but both types never yield any mucoid growth. 3. An old culture of the modified coli obtained by Bordefand Ciuca, when streaked on agar plate, gives two types of colonies: a mucoid and fluorescent type (coli M 1) and a non-mucoid and translucent type (coli M 2). Both types are motile. Coli M 2, once isolated, keeps its individuality even after several passages in artificial media, but if again submitted to the lytic agent, a great number of mucoid bacilli are found among the organisms which are still alive. Consequently, different types of Bacillus coli differ greatly in their ability to give a mucoid growth when submitted to the lytic agent. Some, like coli S and coli R, do not possess this property at all. Others, like coli O, possess it to a certain extent, and some, like coli M 2, have it to a very high degree. 4. The mucoid and motile Bacillus coli M 1, when streaked every day on agar plates, remains indefinitely mucoid and motile, but occasionally a mucoid colony shows an indentation made up of non-mucoid growth, which, transplanted, gives a pure culture of non-mucoid and non-motile organisms, coli M 1 a. This new type possesses all the characteristics of the original strain of Bacillus coli, and therefore must be considered as a reversion. 5. The mucoid and motile Bacillus coli M 1, kept growing in synthetic medium, remains perfectly stable; on the other hand, when it is transplanted in broth, Bacillus coli M 1 turns very quickly into a non-mucoid but still very motile organism, or Bacillus coli M 1 b. This last type, which produces translucent colonies on agar and grows granular in broth, never reverts to the mucoid form, even in the presence of lytic agent. 6. A single strain of Bacillus coli has thus been made to yield eleven different forms, all distinguished by striking characteristics, but still possessing the specific properties of Bacillus coli. Nine of these forms have been submitted to antisera prepared with three different types (Bacillus coli O, Bacillus coli S, and Bacillus coli R). While seven out of these nine strains were agglutinated by any of the three antisera, only the original Bacillus coli (Bacillus coli O) and the reversion to the original type (Bacillus coli M 1 a) were not agglutinable, even by their corresponding antiserum; i.e., the serum obtained from a rabbit immunized with Bacillus coli O, which, however, agglutinated the other types.


The object of the present series of researches is to examine how far the principal general facts in electricity are explicable on the theory adopted by the author, and detailed in his last memoir, re­lative to the nature of inductive action. The operation of a body charged with electricity, of either the positive or negative kind, on other bodies in its vicinity, as long as it retains the whole of its charge, may be regarded as simple induction , in contradistinction to the effects which follow the destruction of this statical equilibrium, and imply a transit of the electrical forces from the charged body to those at a distance, and which comprehend the phenomena of the electric discharge . Having considered, in the preceding paper, the process by which the former condition is established, and which consists in the successive polarization of series of contiguous particles of the interposed insulating dielectric; the author here proceeds to trace the process, which, taking place consequently on simple induction, terminates in that sudden, and often violent interchange of electric forces constituting disruption , or the electric discharge. He investigates, by the application of his theory, the gradual steps of transition which may be traced between perfect insulation on the one hand, and perfect conduction on the other, derived from the varied degrees of specific electric relations subsisting among the particular substances interposed in the circuit: and from this train of reasoning he deduces the conclusion that induction and conduction not only depend essentially on the same principles, but that they may be regarded as being of the same nature, and as differing merely in degree. The fact ascertained by Professor Wheatstone, that electric conduction, even in the most perfect conductors, as the metals, requires for its completion a certain appreciable time, is adduced in corrobo­ration of these views; for any retardation, however small, in the transmission of electric forces can result only from induction; the degree of retardation, and, of course, the time employed, being proportional to the capacity of the particles of the conducting body for retaining a given intensity of inductive charge. The more perfect insulators, as lac, glass and sulphur, are capable of retaining electri­city of high intensity; while, on the contrary, the metals and other excellent conductors, possess no power of retention when the in­tensity of the charge exceeds the lowest degrees. It would appear, however, that gases possess a power of perfect insulation, and that the effects generally referred to their capacity of conduction, are only the results of the carrying power of the charged particles either of the gas, or of minute particles of dust which may be present in them: and they perhaps owe their character of perfect insulators to their peculiar physical state, and to the condition of separation under which their particles are placed. The changes produced by heat on the conducting power of different bodies is not uniform; for in some, as sulphuret of silver and fluoride of lead, it is increased; while in others, as in the metals and the gases, it is diminished by an augmentation of temperature.


The method used in the preceding paper implies that it is only the motion of the adsorbed atom perpendicular to the surface which is changed by the interaction of the solid, and the object of this paper is to remove that restriction and to formulate the method in more general terms. We suppose the adsorbed atom held by one of the atoms of the solid in such a way that it can vibrate relative to it not only radially but also laterally. Whereas in the example worked out in the preceding paper the adsorbed atom could vibrate normally to the surface and migrate freely along it, in the example considered in this paper the adsorbed atom an vibrate radially and laterally but cannot migrate. Owing to the other atoms of the surface, the motion of the adsorbed atom is confined to one side of a plane and the lateral motion can be regarded as taking place on a hemisphere. We suppose that the field of attraction can be represented by a function of the distance from the attraction can be represented by a function of the distance from the attracting centre.

A three-party quantum secure direct communication protocol is proposed, in which the qubit transmission forms a closed loop. In this scheme, each party implements the corresponding unitary operations according to his secret bit value over the quantum channels. Then, by performing Bell measurements on the encoded particles, each party can extract the other two parties’ secret information simultaneously. Thus the three parties realize the direct exchange successfully.
