In recent years, there has been a good deal of controversy about the application of infinitesimal kinematics to the mobility determination of kinematic chains. On the one hand, there has been several publications that promote the use of the velocity analysis, without any additional results, for the determination of the mobility of kinematic chains. On the other hand, the authors of this contribution have received several reviews of researchers who have the strong belief that no infinitesimal method can be used to correctly determine the mobility of kinematic chains. In this contributions, it is attempted to show that velocity analysis by itself can not correctly determine the mobility of kinematic chains. However, velocity and higher order analysis coupled with some recent results about the Lie algebra, se(3), of the Euclidean group, SE(3), can correctly determine the mobility of kinematic chains.

SummaryThe importance and difficulties of determining the height of hard X-ray sources in the solar atmosphere, in order to distinguish source models, have been discussed by Brown and McClymont (1974) and also in this Symposium (Brown, 1975; Datlowe, 1975). Theoretical predictions of this height, h, range between and 105 km above the photosphere for different models (Brown and McClymont, 1974; McClymont and Brown, 1974). Equally diverse values have been inferred from observations of synchronous chromospheric EUV bursts (Kane and Donnelly, 1971) on the one hand and from apparently behind-the-limb events (e.g. Datlowe, 1975) on the other.

Res Publica

While the exact meaning of Res Gestae 34, the powers of Augustus at various moments in his principate, and the significance of his auctoritas have been extensively argued, more practical questions about how his political arrangements might have been set into action have not generally excited much interest. In 1974 I put forward a suggestion about how the so-called first settlement of 27 B.C. came about. It was, in brief, that Octavian, as he then was, used the traditional consular mechanisms, and proposed for debate in the Senate a motion, de provinciis consularibus, and this explains why, on the one hand, the result of the debate was that he had provinces allocated to him, and, on the other, claims could be made that the res publica was restored, because one of the things which characterized res publica (as distinct from dictatorship or triumviral rule) was that the determination of who should command which army stationed in the provinces now lay, ostensibly at least, with the publicum consilium, the Senate.

However extractions always involve a serious decrease in sensitivity, while evaporation of the extract produces a solution in 0.1-0.5 ml of solvent, and only 1 pi of it can be brought in the gas chromatograph. Therefore work is in progress to enhance sensitivity by converting acids in­ to halogenated derivatives, which can be GC-analysed with the more sensitive electron-capture detector. For thiols a similar procedure is investigated as with aldehydes. One possibility is absorption of thiols in an alkaline solution and reaction with 2,4-dinitrochlorobenzene, yielding 2,4-dinitrofenylsulfides, which are analysed by HPLC (9). Sane improvements on removal of reagents at the one hand and on separation of sane by-products on the other hand have to be achieved in order to in­ crease the sensitivity with another factor of ten. 5. CONCLUSION The actual scope and limitations of chemical analysis of odour show that all problems can be tackled as far as emission is concerned. For iititiission measurements seme progress is necessary, but there is no essential reason why chemical analysis would be unable to attain the desired sensitivity for all types of odorants. There is no doubt that in a few years the last dif­ ficulties will be solved. In order to achieve real control of odour nui­ sance, automatic measurement is necessary on a long time basis. There again seme technical development is to be expected. Does this mean that machines are going to decide if an odour is pre­ sent or not? By no means, while the population will always be the reference, and psychophysical measurements will be necessary to make chemical analysis possible.

The Relationship

Although a good deal of recent critical attention to Melville's writing has followed the lead of Robert K. Martin in addressing the issue of sexuality, the predominant themes in discussions of “Bartleby” remain changes in the nature of the workplace in antebellum America and transformations in capitalism. But, if one of the abiding mysteries of the story is the failure of the lawyer–narrator to sever his relationship with his young scrivener once Bartleby embarks upon his policy of preferring not to, it is a mystery that makes sense within both of these critical discourses. On the one hand, the longevity of the relationship dramatizes a tension implicit in Michael Gilmore's suggestion that the lawyer–narrator straddles the old and the new economic orders of the American market-place. Although he may employ his scriveners “as a species of productive property and little else”, his attachment to his employees is overwhelmingly paternalistic and protective. On the other hand, James Creech suggests that Pierre (published the year before “Bartleby”) is a novel preoccupied with the closeting of homosexual identity within the values of an American middleclass family, while Gregory Woods describes Melville as the nearest thing in the prose world of the American Renaissance to the Good Gay Poet Whitman. In this critical context the longevity of the relationship suggests that the lawyer–narrator's desire to know Bartleby, to protect him, to tolerate him, to be close to him, to have him for his own, and then to retell the story of their relationship, needs to be considered in relation to sexual desire.

That several of the planets as well as that which we inhabit are surrounded by atmosphere, astronomical observations have long since established; the extent, however, to which in particular planets such atmospheres are diffused, is as yet not satisfactorily determined. The former rests principally upon phenomena observed on the planets’ discs, whilst the latter derives its support chiefly from those detected at or near their respective limbs. Every night, nay almost every hour, may give us indication of the one, whilst years are sometimes necessary, as in the case of planets unattended by satellites, to help us to the other; thus the hypothesis of the extensive atmosphere of Mars derives its origin from the observations of Cassini and Roëmer, and has stood more than a century and a half without refutation or support. The observations to which I allude formed part of a series undertaken for the determination of the parallax of Mars, and are recorded in the Mémoires de l’Académie des Sciences. Cassini’s were made at Briare and at La Charité sur Loire; whilst Roémer’s was obtained at the Royal Observatory of Paris.

A dichotomous key for determination of serological groups among Streptomyces is described. This key is limited in that only seven specific antisera are used for testing. The utility and reliability of the application of this key were tested and compared to the results of previous taxonomic studies reported on the basis of biochemical and morphological characteristics of these organisms. Results indicate the desirability of using a combination of methods including serological characteristics on the one hand, and biochemical–morphological characteristics on the other, to increase the reliability of taxonomic studies.

The following paper contains the results of a series of inquiries, which lead to the conclusion, that the mineral called Smaragdite by Saussure, does not form a species of its own; but that this name has been given to a compound of certain varieties of two distinct species, Augite and Hornblende, the natural-historical species of paratomous and hemiprismatic Augite-spar.Owing in part to the slight degree of resemblance prevailing among its varieties, the authors who have described them differ so essentially in opinion, that I am obliged to go into various details, both respecting the external appearance of the mineral itself, and of the opinions of mineralogists, in order to afford a correct view of the natural-historical species, to which these varieties belong, since this is the basis upon which every system, and, indeed, all accurate information in natural history, is founded, and the fixed point to which the one and the other must be referred.

Historians of Chartism face a dilemma. On the one hand, they are obliged to interpret this national political movement on the national level, to attempt to explain why millions of British working men and women were engaged in organized political activity over several decades. But, on the other hand, many of the richest sources on Chartism are found on the local level. Older histories of the movement treated Chartism from a national perspective, but failed to take note of many of its complexities. More recently, a good deal of local research has rigorously tested our assumptions about Chartism, but the task of carefully analyzing the movement on the national level still remains.

Much controversy has raged for a long period of time over the precise nature of what Wormser refers to as the “anatomy” of a corporation. Wormser himself defines a corporation as a “group of one or more persons authorized by sovereign authority to act as a unit and a personality in the eye of the law.” The definition indicates, on the one hand, that the act of incorporation creates a new person or entity, on the other that this new entity is in fact composite, made up of one or more pre-existing entities. The question arises, at what times will the court regard the corporate entity, and at what times will it look to the real persons who compose it ? A key to the solution of the problem is offered by Lord Mansfield. “A fiction of law shall never be contradicted so as to defeat the end for which it was invented, but for every other purpose it may be contradicted.” By the separate entity theory is meant that a corporation is to be regarded as an entity separate and apart from its corporators and that it is to be treated like any other independent person. That this is the theory of corporations generally accepted by the courts need hardly be proved. It will only be noted that the ruling English case on the subject is that of Salomon and Co. v. Salomon. In his opinion in that case Lord Halsbury said: “Once the company is legally incorporated it must be treated like any other independent person.”
