The discoveries made by the author of the remarkable metamorphoses which the animals composing the first family of the Cirripedes, or Balani , undergo in the progress of their developement, and which he has published in the third number of his Zoological Researches (p. 76), are in the present paper, which is intended as a prize Essay for one of the Royal Medals, followed up by the report of his discovery of similar changes exhibited by three species of two other genera of the second tribe of this family, namely, the Lepades . The larvæ of this tribe, like those of the Balani, have the external appearance of bivalve Monoculi, furnished with locomotive organs,in the form of three pairs of members, the most anterior of which are simple and the other bifid. The back of the animal is covered by an ample shield, terminating anteriorly in two extended horns, and posteriorly in a single elongated spinous process.

The Fourth Memoir, published in my Zoological Researches and Illustrations, No. III. page 69, &c., having first made known the real nature of the Cirripedes , the key of which remained concealed in their metamorphosis, it might have been expected that some naturalist favourably situated to investigate the oceanic tribe of these animals, would have been the first to make the same discovery in regard to these, and thereby complete their natural history. It was scarcely to be expected that the honour of this discovery also should be reserved for the author, fixed to one spot, where none of them naturally exist, and are but casually thrown upon our shores by the waves of the Atlantic, attached to pieces of wreck, or brought into port fixed to the bottoms of ships returning from distant voyages. Fortunately, however, two ships of this description came into this harbour (Cork), one from the Mediterranean, the other from North America, which, not being sheathed with copper, had their bot­toms literally covered with Barnacles of the three genera of Lepas , Cineras , and Otion ; and having persons employed expressly for the purpose, numbers of these were brought alive in sea water, amongst which were many with the ova in various stages of their progress, and some ready to hatch, which they eventually did in prodigious numbers, so as to enable him to add the proof of their being, like the Balani, natatory Crusta­cea in their first stage , but of a totally different facies and structure; a circumstance which determines the propriety of the separation of the Cirripedes into two tribes, and evinces the sagacity of Mr. MacLeay in being the first to indicate that these two tribes, the Balani and Lepades , were not so closely related as generally supposed. The larvæ of the Balani , described in Memoir IV. under the external appearance of the bivalve Monoculi ( Astracoda ), have a pair of pedunculated eyes, more numerous and more completely developed members, approximating to those of Cyclops , and of the perfect Triton ; while, in the present type, or Lepades , the larva resembles some­what that of the Cyclops , which Müller, mistaking for a perfect animal, named Amymone , and which can be shown to he common to a great many of the Entomostraca ; or the resemblance is still more striking to that of the Argulus Armiger of Latreille, which, in fact, is but an Amymone furnished with a tricuspidate shield at the back.

The necessity of discussing so great a subject as the Theory of the Vertebrate Skull in the small space of time allotted by custom to a lecture, has its advantages as well as its drawbacks. As, on the present occasion, I shall suffer greatly from the disadvantages of the limitation, I will, with your permission, avail myself to the uttermost of its benefits. It will be necessary for me to assume much that I would rather demonstrate, to suppose known much that I would rather set forth and explain at length; but on the other hand, I may consider myself excused from entering largely either into the history of the subject, or into lengthy and controversial criticisms upon the views which are, or have been, held by others. The biological science of the last half-century is honourably distinguished from that of preceding epochs, by the constantly increasing prominence of the idea, that a community of plan is discernible amidst the manifold diversities of organic structure. That there is nothing really aberrant in nature; that the most widely different organisms are connected by a hidden bond; that an apparently new and isolated structure will prove, when its characters are thoroughly sifted, to be only a modification of something which existed before,—are propositions which are gradually assuming the position of articles of faith in the mind of the investigators of animated nature, and are directly, or by implication, admitted among the axioms of natural history.

The following observations upon the Natural History of Epidemic Diarrhoea were made in Mansfield during the summer and autumn of 1908. The fact that at the time the writer was engaged in preparing a paper—to which the present paper is to some extent complementary—upon the epidemiological relations of season and disease, lent special interest to the enquiries regularly made from the Health Department of this town into the circumstances attending fatal attacks of diarrhoea. Early in the season a more than usually extensive enquiry was made into one of these fatal attacks in an area where an outbreak of diarrhoea appeared to be spreading outwards from a group of old privy-middens. To test how far the condemnation of the latter was justifiable another area was taken on the other side of the town, where the houses were newly built and provided exclusively with water-closets; and records, collected by house-to-house visitation, were obtained of all cases of epidemic diarrhoea, whether non-fatal or otherwise, occurring in these localities. The enquiries thus begun were afterwards extended so as to embrace two fairly large districts, a chance of doing this being provided by the opportune postponement of the addition to the department of certain work of inspection which had been impending at the beginning of the summer. These districts were several times revisited and scattered observations were also made throughout the other parts of the town. During 1909, while there was no opportunity of making extended observations, there were valuable opportunities during the course of the routine inspections of the summer of testing and re-testing the principal results obtained during 1908.

Lines Of Force

This essay argues that Ralph Waldo Emerson's interest in the cutting-edge science of his generation helps to shape his understanding of persons as fluid expressions of power rather than solid bodies. In his 1872 "Natural History of Intellect," Emerson correlates the constitution of the individual mind with the tenets of Michael Faraday's classical field theory. For Faraday, experimenting with electromagnetism reveals that the atom is a node or point on a network, and that all matter is really the arrangement of energetic lines of force. This atomic model offers Emerson a technology for envisioning a materialized subjectivity that both unravels personal identity and grants access to impersonal power. On the one hand, adopting Faraday's field theory resonates with many of the affirmative philosophical and ethical claims central to Emerson's early essays. On the other hand, however, distributing the properties of Faraday's atoms onto the properties of the person also entails moments in which materialized subjects encounter their own partiality, limitation, and suffering. I suggest that Emerson represents these aspects of experience in terms that are deliberately discrepant from his conception of universal power. He presumes that if every experience boils down to the same lines of force, then the particular can be trivialized with respect to the general. As a consequence, Emerson must insulate his philosophical assertions from contamination by our most poignant experiences of limitation. The essay concludes by distinguishing Emersonian "Necessity" from Friedrich Nietzsche's similar conception of amor fati, which routes the affirmation of fate directly through suffering.

Information on the ecology of lizard species from the Brazilian Atlantic Forest is scarce and almost nothing is known about the ecology of lizards of the genus Enyalius. In this study, we provide information about some aspects of the natural history of E. brasiliensis from an area of Atlantic Forest in Ilha Grande, RJ. Enyalius brasiliensis (N = 15) feeds mainly on arthropods. The most frequent food items were insect larvae, orthopterans, and ants; in terms of volume, larvae and termites were the most important food items; ants and termites were the most numerous prey categories. Two females were reproductive (one had 10 and the other, five vitellogenic follicles); the smallest measured 92.4 mm in SVL. Seven lizards were found on forest leaf litter. The other microhabitats used were vines, fallen logs, branches, and a crevice on a slope.

The Disputationes Camaldulenses of Cristoforo Landino constitute an important document. Composed in the manner of Ciceronian dialogues, they present us with a group of speakers famous in the history of Florentine thought: among others, Lorenzo de’ Medici, Alberti, and Ficino of the ‘Platonic Academy’ at Careggi to which Landino belonged; Alamanno Rinuccini, the Acciaiuoli, and Marco Parenti of the other ‘academy', presided over by Argyropoulos. The first dialogue deals with the relative merits of the active and contemplative life, the second with the problem of the highest good—two topics dear to the Renaissance. The third and fourth give an allegorical interpretation of the Aeneid. It would be hard to find personages or themes more central to quattrocento intellectual history. Inevitably one looks to the Disputationes for the light they throw on these Florentine scholars and on their interests.

Layer Concept

FROM the viewpoint of the pediatric psychiatrist, the problems of obesity, as seen clinically, can be thought of as having three layers. The first is constitutional, better described as physiologic, which may be broken down into genetic and structural elements. The second is psychologic, consisting of the values that food intake or the obesity itself come to have. The third layer is made of the cultural and social reactions to food and fat. These attitudes encountered inside and outside the home intermesh in their effects with the physiologic and psychologic levels. These, in turn, are also interwoven, until one cannot separate one layer from the other. However, when individual cases are scrutinized they reveal the pathology at one layer or the other to predominate and indicate where efforts to modify the abnormality might best be directed. Incidentally, the same levels operate on the other side of the coin, anorexia. From the practical point of view, let us consider the natural history of obesity and the clinical varieties one sees in practice, and let us see how the three-layer concept fits. First, as pointed out by Gordon, there is a tendency to be complacent or even pleased with obese infants. At level one, the physiologic, such constitutional factors as those present in the neonate born with an excessive quantity of pepsinogen secreted by the gastric mucous membrane could have the effect of producing as Mirsky points out, a relatively intense or even continuous hunger, and make greater demands on its mother for nursing.

This paper argues that the methodology Francis Bacon used in his natural histories abides by the theoretical commitments presented in his methodological writings. On the one hand, Bacon advocated a middle way between idle speculation and mere gathering of facts. On the other hand, he took a strong stance against the theorisation based on very few facts. Using two of his sources whom Bacon takes to be the reflection of these two extremes—Giambattista della Porta as an instance of idle speculations, and Hugh Platt as an instance of gathering facts without extracting knowledge—I show how Bacon chose the middle way, which consists of gathering facts and gradually extracting theory out of them. In addition, it will become clear how Bacon used the expertise of contemporary practitioners to criticise fantastical theories and purge natural history of misconceived notions and false speculations.

Jewish Emigration

This chapter discusses the book Studia z dziejów i kultury Żydów w Polsce po 1945 roku (Studies on the History and Culture of Jews in Poland after 1945), which was edited by Jerzy Tomaszewski. This volume consists of three short monographs by Polish graduate students in the early stages of their professional development. Two were originally written as MA theses: one by Maciej Pisarski on Jewish emigration from Poland from 1945 to 1951, and the other by Albert Stankowski on Jewish emigration from western Pomerania from 1945 to 1960. The third, by August Grabski, on the organization of Jewish religious life in Poland during the communist and (primarily) post-communist eras, originated as a seminar paper. On the whole, postgraduate writing of this type, if it is published at all, appears in limited-circulation journals for an audience of academics. The fact that these studies were published in book form, especially in paperback with the aid of a subsidy from the Polish Ministry of Culture, offers further testimony of the keen interest in the history of Jews in Poland evident among the Polish public in recent years.
