This paper discusses the content and characteristics of a hitherto unexamined manuscript Tenmongata kakitome (Astronomical Note), Isahaya City Library, Nagasaki. This anonymous and undated manuscript is a compilation of 83 short passages concerning mainly Western astronomy and geography. Although almost all the passages lack information about the sources from which they are taken, textual comparison clearly reveals that a half of them (41 passages) corresponds to the text of the Nigi ryakusetsu, a typical of Nanban astronomy books which originated from Jesuit missionary activities during the 'Christian century' in Japan (1549-1650). Moreover, the other passages contain much information relating to Rangaku (Dutch studies), such as Latin and Dutch texts with Japanese translations. Textual comparison reveals that some of them obviously correspond to those seen in the Nichigetsukei wage (Translation about the sundial and moondial) of Motoki Ryoei (1735 -1794), a famous Nagasaki interpreter of Dutch. These facts show that this compilation was completed later than the Tenmei era (1781-1788), probably around Nagasaki, by extracting and combining several texts of the two books as well as the other sources. In effect, the Tenmongata kakitome is not only a rare example which illuminates the transmission of these two books, but also provides the evidence that the two lines of circulation, i.e. those of Nanban and Rangaku astronomy, which were hitherto thought un-interrelated, certainly met each other at least later than the Tenmei era.

The Hippocratic treatise De Vetere Medicina (On Ancient Medicine) has been the focus of attention among classical scholars and historians of medicine. The author attacks in ch. 20 doctors and sophists who base their own medical theories and methods on philosophical anthropology taken from the contemporary natural philosophers. Many attempts have been made to elucidate, as opposed to their philosophical inquiry into human nature, the author's way of understanding it, which still remains unclear. I draw attention to the following points to make it clear that the conceptual framework of the author's medical anthropology is different from theirs. Their philosophical inquiry into human nature has its starting point in fundamental element(s), from which human beings were originally formed. The author focuses on human beings as existent in their present states, whose conditions and functions must be investigated through interrelations between them and their external factors, such as foods and drinks. A medical investigation into the interrelations will give us a scientific idea about human body, whose constituents are taken to be a large number of humors, reacting against some external factors and accordingly making us feel pain. This may presuppose that, in the author's medical anthropology, human body is conceptually demarcated as the physical or material aspect of human being, within which all physiological events depending on external factors and the humors take place. In their philosophical anthropology, however, human body doesn't seem to have been clearly conceptualized as such, because our experience of feeling pain should be judged to take place within the actions of the fundamental element(s), which must be supposed to constitute our cognitive self.

Although newtonian mechanics is the most familiar formulation of classical mechanics, we have an another one called variational mechanics. Leonhard Euler attempted to solve some mechanical problems using the latter idea and gave two variational-mechanical laws : "law of rest " in statics, and "law of motion " in dynamics. He maintained that these two laws were "in harmony ", namely that the one could be derived from the other. Moreover, they are both based on "principle of least action, " according to which some quantities are minimum in physical phenomena. In effect, "law of rest " asserts that the sum of "efforts " for bodies is minimum in equilibrium, which Euler interprets as the evidence of the intention of nature to "save efforts. " "Law of motion " determines the trajectory of a mass point, in which "action " is minimum; according to Euler, this could be explained by the inertia of bodies. These laws show Euler's faith in his principle, even though he doesn't use the condition of "minimum " in solving concrete problems; therefore, his "principle of least action " is not a mathmatical requirement. His demonstration of the "harmony " is also based on the belief that nature "saves efforts. " This attempt is, however, a failure in a double meaning; we can't prove the "harmony " from the point of modern view, and Euler's proof is inconsistent with his own "principle of least action. " "Euler's variational mechanics " has failed to realize a unified treatment of statics and dynamics, because it was built up on the "principle of least action. "

This paper examines the process and development of revolutionary data of thermal radiation in the late 19th century, focusing on Friedrich Paschen's experimental research in the early to mid-1890s. The well-known experiments of O. Lummer and E. Pringsheim, H. Rubens and F. Kurlbaum had brought about the suggestive results concerning Planck's radiation law. Paschen's research played an important role in pioneering experimentalists who were active in the early 1890s. Before Lummer, Pringsheim, Rubens, and Kurlbaum made a series of experiments on the radiation law, Paschen had begun to research on the "Normal Spectrum " representing the spectral distribution of radiation energy. He had made it to examine the spectrum of diffraction grating with the directions of H. Kayser in 1891-1892. In the meantime, other experimentalists such as Lummer and Rubens conducted research on the measurements of luminous intensity and electricity at the request of refining the standards. In 1893 Paschen improved the foundation for experiments on thermal radiation by utilizing those different kinds of measurements and made a step forward in the precision measurements of radiation distribution function.

In this paper, I examine the reason for the subsidence of Soviet dispute over philosophical legitimation of modern physics in the late 1930s. The battle of scientists against party ideologues or their sympathizers was politically adventurous in the period of the Great Terror. In fact, established scientists such as Nikolai Vavilov were severely accused by opponents and were led even to be imprisoned. However, in spite of the heated attack to some leading physicists in the dispute over modern physics in philosophical journals, the worst tragedy was avoided in general. I maintain that Sergei Vavilov, one of the most influential physicists of this period, acted as a crucial negotiator in this process. By learning the Marxist terminology or a politically correct attitude in the discourse, Vavilov succeeded in soothing the party ideologues and at the same time guarding modern physics or physicists. In some respect he made a compromise, but it was a very valuable one.
