In this paper, the results of the investigations of the Tachiyazawagawa are reported. The results are summarised as. follows:- 1. The water temperature of the river is lower than that of the Mogami (main stream) throughout the snow-melting season. The diffe-rence, lies 1.3 and 5.1. 2. The upper reaches of the river consist of the Nigorisawa, the Honsawa (the main stream) and the Akasawa. Among the three, the Nigorisawa is most influenced by the volcanic activity of Mt. Gassan, judging from the chemical analysis of the water taken from the stations in the drainage system. 3. The content of the dissolved oxygen in the water undergoes the diurnal change. The relation between the oxygen content and the water temperature nearly shows the negative correlation. 4. The chloride content of the river decreases regularly with the increase of the flow except during the snow-melting season.

The author has been studying the distribution and variation of population In the middle of Edo Period by “Junkoki” that is a historical work of Owari Clan. This book was recorded by “Kôko Higuti” (1750-1826) who inspected all the villages within Owari Province. In this “Junkôki” he recorded two sets of population number, the one is of the year of 1671 A. D. and the other is of some year of the early 18 th century.<br> Fig. 1 shows the rates of the increase or decrease of population of each village gained from the comparison of two sets of population noted in “Junkoki.” And the author classified those rates into five classes:<br> 1. Remarkable Increase, 2. Increase, 3. Sluggish Increase, 4 Stagnation, 5. Decrease.<br> Fig. 2 shows the accumlated population on each administrative unit at the time of 1915. Hereupon one can see the regions of increased or, decreased population by these figures. It was the head region of Ise Bay, eastern Highland and Tita Peninsula that increased remarkably in population. Because. the head region of Ise Bay was reclaimed land, this increase of population in this region resulted from the migration of the people from the neighbouring land (Fig. 3). The most of the eastern part of the highland and Tita Peninsula were cleared regions and there were constru-cted many irrigation ponds or canals by which cultivated lands were enlarged and. the population was increased. In this region, there were some industrial centres such as Seto City and its suburbs and Tokoname Town on the west coast of Tita Peninsula, where industries were ceramics, - - - -Arinzatu Town, variegation of cloth, - - - the most part of the peninsula, textile of cotton, - - -Handa City and its neighbourhood brewing --- the coast of peninsula, marine transportation. And these industries had been developed into the stage of“ manufacture” in the middle of Edo Era. Consequently, the development of these industries brought about the increase of population in the districts above mentioned. Contrary to these regions, the middle part of the Owari Plain and the outskirts of Nagoya were the districts of the stagnation or decrease of population. Since agriculture was a principal occupation, having been conti-nuously developed front ancient time, it was impossible to attempt the expansion of cultivated fields, and as the result there was difficulty in increasing the population in this area. In addition to these conditions, the Castle Town of Nagoya was absorbing the rural population, and so it was decreasing remarkably. Besides those regions, the ports on the head of Tita Peninsula, such as Morozaki and Toyohama, lost some of their population for their narrow hinterland and the shortage of cultivated land.<br> The distribution and variation of population under the feudal system were different from those under the capitalistic economic system. These differences are based on the differences of the basic industries and the scale of the cities under these two systems.

メマンチンは中等度,重度のアルツハイマー病(AD)の治療薬としてEUとアメリカで承認されている.メマンチンはMK-801やフェンシクリジン(PCP)と同じ非競合的NMDA受容体阻害薬であり,虚血が引き起こすグルタミン酸過剰放出による神経細胞死を防ぐ.これらの薬物はマグネシウムイオンと同じイオンチャネル結合部位に作用する.しかし,MK-801やPCPは統合失調症様症状を引き起こし,ADの治療薬としては使用されていない.メマンチンには類似の毒性はない.また,大脳皮質でのアセチルコリン放出は起きない.メマンチンとMK-801との相違の機構はまだ解明されていないが,メマンチンはマグネシウムイオンと同様に電位依存的にイオンチャネルへ結合し,解離するためと考えられている.今後メマンチンに関する基礎的,臨床的研究が進み,機構が解明されるであろう.

At Daiichi Dam of the Tachiyazawa River, the amount of dissolved oxygen and the water temperature are observed throughout the day. The hourly observation reveals that the linear relationship (negative correlation) is found to exist between the two. Regarding this river, the following equation is obtained:DO=13, 98-0.367 Tw (r=-0.933), where DO is dissolved oxygen in ppm and Tw in °C.

The Chokai Volcano, which lies on the coast of the Japan Sea, is one of the famous volcanoes of the northeast Japan, and <i>Tori-no-umi</i> is the crater lake near the top of this volcano. This is a report of the limnological survey of this lake.<br>1) This lake has an elliptical shape as is shown by the bathymetric map (Fig. 2).<br>2) As seen from Figs. 4 and 9, the vertical distribution of the water temperature and the chemical quality shows typical features at the periods of the summer stagnation and the autumnal circulation.<br>3) The result of the chemical analysis (Tables 2-4) generally reveals that <i>Tori-no-umi</i> is poor in dissolved substances.<br>4) This lake is characterized by rather high concentration of Na<sup>+</sup> and Cl<sup>-</sup>. (These features are not seen in the several lakes in the Zao and the Shirataka Volcano areas distant from the Japan Sea coast.) The writers inferred that the chemical quality of <i>Tori-no-umi</i> lake is originated from the atmospheric salt in the remaining snow around the lake.
