The work described in this paper is based, very largely, on the work of Dean and Webb (1926), and the methods used in the various experiments are similar to those described by them. The results are discussed in two parts. The first is concerned with the mixture of different specimens of anti-horse serum, and with the relationship of the antibody in one specimen to the antibody in another. The second part deals with the nature of the reaction between antigen and antibody in the serum precipitation reaction. The two parts are dependent on each other, and the subject of the second suggested itself whilst the work on the first was in progress. The order in which the work is described is mostly that in which it was done. Nevertheless, conclusions arrived at in one part are, in one or two cases, of importance in the consideration of the other part, and vice versa. A question as to the possibility of strengthening the ratio of an antiserum by the addition of another antiserum led to the earlier experiments.

In explaining the nature of international law, each of the two major schools of thought draws upon legal philosophy and practice for evidence in support of its interpretation. It is not the purpose of this note to offer any conclusions or proofs as to the validity of the reasoning of one or the other of the two schools. It would require more than the subject-matter here considered to prove the “Monist” position, or to detract from that of the “Dualist.” However, inasmuch as state practice is one of the guides to the resolution of the debate on the nature of international law, it is hoped that an explanation of the attitude of the Colombian Supreme Court concerning the relationship of pacta to the national constitution and legislation of that state may merit mention.

A relação de Hegel com o ceticismo está longe de ser clara. A par de existirem alguns poucos trabalhos sobre o assunto, e de Hegel abordar o tema em várias obras, não está bem determinado se Hegel possui uma teoria global sobre o ceticismo ou se apenas é um mero crítico de posturas céticas clássicas na antiguidade e na modernidade. Em que pese Hegel ser um crítico ferrenho do ceticismo moderno (por ex., em textos como Sobre a relação do Ceticismo com a Filosofia, as Preleções sobre História da Filosofia e a Enciclopédia das Ciências Filosóficas), a sua crítica não se restringe a esta ou aquela forma de ceticismo, mas se funda numa teoria geral do saber que compreende o ceticismo como uma atividade negativa constitutiva da consciência e pretende refutá-lo enquanto ele reifica essa negatividade numa pretensão de verdade. A refutação consiste na descrição do modo como o ceticismo filosófico seria um saber parcial, e por isso auto-refutativo. O presente trabalho pretende sugerir que isto ocorre, sobretudo, na Fenomenologia do Espírito, cujo caráter “fenomenológico” propriamente dito não parece poder ser bem compreendido, sem tomar como pano de fundo o problema do ceticismo. PALAVRAS-CHAVE – Hegel. Fenomenologia. Ceticismo. Refutação. ABSTRACT Hegel’s position towards skepticism is far from being clear. On the one hand, there are just a few studies on the subject and Hegel faces the issue in several of his writings; on the other hand, it is not established yet if Hegel has a global theory about skepticism or if he is just a critic of Ancient and Modern skeptical attitudes. In spite of Hegel being known as a sharp critic of Modern skepticism (for example, in works like On the relationship of skepticism to philosophy, Lectures on the history of philosophy and Encyclopedia of philosophical sciences), his criticism is not restricted to specific forms of skepticism, but it is rather founded upon a general theory of knowledge which takes skepticism as a negative activity constitutive of our natural consciousness and intends to refute the skeptical attitude as that negative activity of self-consciousness is reified and turned out into a special kind of truth claim. Hegel’s refutation consists in describing the way philosophical skepticism would be understood as a partial and self-defeating attitude of knowing. The present study suggests that this procedure is to be seen above all in the Phenomenology of Mind, whose “phenomenological” character cannot be rightly understood without taking properly into account the problem of skepticism. KEY WORDS: Hegel. Phenomenology. Skepticism. Refutation.

Exegi monumentum aere perennius.… non omnis moriar. From Horace onward, the relationship of art to human mortality has been a major theme in literature – and one which obviously interested Browning, if we may judge from some striking variations he worked on it. In “Cleon” and “Abt Vogler,” for example, his speakers address the subject from very different points of view: Cleon, the pagan, argues that the fact his art will survive after his death cannot in any meaningful way confer immortality on him and that, as an artist, he even more than others is painfully aware of his own limited life; Abt Vogler, on the other hand, confident of the changelessness of God's good, sees in his art a promise that both he and his improvisation will endure. Given Browning's penchant for pushing ideas to extremes and turning them in unusual directions, it is not surprising that he would treat the topic in other less predictable ways – as he did, for example, by making the inert changelessness of works of art in “The Statue and the Bust” comment ironically on human failure to act, or by endowing the worldly and sensuous Bishop at St. Praxed's with an appropriately literal faith in the kind of immortality a suitably artful tomb would confer upon him. It is not surprising, then, that similar topics would appear in “A Toccata of Galuppi's.”

The subject of the article is the relationship of the human entity (monad) to other entities and to the world as a whole. The author discusses the problem within the ontological, political and moral contexts. She is interested in the status of the monad as an isolated being, separating itself from the other and in the conditions necessary for its integration with others. The author turns particular attention to a “social monad” i.e. a set of beings locked in their collective solitude due to the rejection of anything foreign. “The social monad” constitutes a category that makes xenophobic attitudes and causes of social exclusion susceptible to analysis.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.


During the last few years of his life Prof. Simon Newcomb was keenly interested in the problem of periodicities, and devised a new method for their investigation. This method is explained, and to some extent applied, in a paper entitled "A Search for Fluctuations in the Sun's Thermal Radiation through their Influence on Terrestrial Temperature." The importance of the question justifies a critical examination of the relationship of the older methods to that of Newcomb, and though I do not agree with his contention that his process gives us more than can be obtained from Fourier's analysis, it has the advantage of great simplicity in its numerical work, and should prove useful in a certain, though I am afraid, very limited field. Let f ( t ) represent a function of a variable which we may take to be the time, and let the average value of the function be zero. Newcomb examines the sum of the series f ( t 1 ) f ( t 1 + τ) + f ( t 2 ) f ( t 2 + τ) + f ( t 3 ) f ( t 3 + τ) + ..., where t 1 , t 2 , etc., are definite values of the variable which are taken to lie at equal distances from each other. If the function be periodic so as to repeat itself after an interval τ, the products are all squares and each term is positive. If, on the other hand, the periodic time be 2τ, each product will be negative and the sum itself therefore negative. It is easy to see that if τ be varied continuously the sum of the series passes through maxima and minima, and the maxima will indicated the periodic time, or any of its multiples.

Research in English language teaching has highlighted the importance of teaching communication skills in the language classroom. Against the backdrop of extensive research in everyday communication, the goal of this research was to explore whether current discourse analytic research is reflected in the lessons and communication examples of five English language teaching textbooks, by using spoken requests as the subject of investigation. The textbooks were evaluated on five criteria deriving from research on politeness, speech act theory and conversation analysis. These included whether and the extent to which the textbooks discussed the cultural appropriateness of requests, discussed the relationship of requests and other contextual factors, explained pre-sequences and re-requests and provided adequate practice activities. This study found that none of the coursebooks covered all of the criteria and that some coursebooks actually had very inadequate lessons. The results of the textbook analysis demonstrate that teachers using these five coursebooks and designers of future coursebooks must improve their lessons on requests by using pragmatics research and authentic examples as a guide.

This study examines the relationship between physical activity in sport and feelings of well-being, testing alternative interpretations of the relationship between these two variables. It was expected that there would be positive relationships between physical activity on the one hand and physical fitness, feelings of well-being, social interaction in the sport and exercise environment, and socioeconomic status on the other hand. It was also expected that physical fitness, social interaction, and socioeconomic status would be positively related to psychological well-being. Further, it was expected that any positive zero-order relationship of physical activity and well-being would be at least in part a result of the conjoint effects of the other variables. The analyses were conducted separately for the male and female subsamples of a large survey study of Canadian adults. The results, after controls, show a modest positive relationship of physical activity and well-being for males but no such relationship for females. The predicted independent effects of the control factors obtained for both males and females. Interpretations of the results are discussed.

One hundred four healthy premature infants, of birth weight 1,000 to 1,800 gm, were fed one of five feedings: (1) human milk; (2) human milk plus 13 meq/l of sodium chloride; (3) human milk plus 13 meq/l of sodium chloride and 18 meq/l of potassium chloride; (4) a half-skimmed cows milk formula; and (5) a partially-skimmed vegetable oil, cows milk formula. The infants fed any of the three human milk formulas gained weight at a slower rate than the infants fed either of the two cows milk formulas. Infants whose diets were changed from unmodified human milk to the half-skimmed cows milk gained large amounts of weight, and at times were visibly edematous. Infants whose diets were changed from the human milks with added sodium chloride, to the half-skimmed cows milk, gained lesser amounts of weight and did not become edematous. The infants fed the two cows milk diets gained similar amounts of weight, although one diet provided 6.5 gm/kg/day, the other 3.1 gm/kg/day of protein.

Eosinophilia is a constant feature of Loffler's endomyocardial fibrosis.1,2 Three cases of this syndrome have been described in which acute lymphoblastic leukemia was concurrently present.3,4 Cytogenetic evidence in one of these cases suggested that the eosinophilia was "reactive" because the eosinophils had a normal karyotype while the lymphoblasts showed chromosomal aneuploidy.4 The subject of eosinophilia and eosinophilic syndromes has been extensively reviewed by others.5-8 The purpose of this report is to describe a boy with long-standing eosinophilia who presented with intractable heart failure, striking peripheral blood eosinophilia, and 38% lymphoblasts in the bone marrow. Current thoughts concerning the relationship of endomyocardial fibrosis, acute lymphoblastic leukemia, and eosinophilia are summarized.
