1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are developed... 1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are developed from the asexual mother either singly or in combination with other kinds and asexual daughters.6. Parthenogonidia develope very early in young embryos long before the latter become matured and escaped from the mother colony. 7. During the early development of parthenogonidia, at least from first to fifth or sixth divisions, no growth of the whole embryo takes the place while the number of cells increases.8. Spermatogonia attain fully-grown size and begin to divide before the time of the birth of the colony.9. The development of spermatogonium consists of seven successive divisions in forming a bundle or platelet of one hundred and twenty eight spermatozoa or microgametes.10. The number of ovaries in a female colony varies from twelve to fourty six. Generally, the larger the colony, the more the ovaries developed.11. Risexual colonies contain only two or three spermatogonia in addition to fourteen to twenty seven ovaries.12. In general, specimens recorded in Nanking are identical to those from the tropical regions such as Africa and the Philippine Islands. 關於菲洲團走子之分佈,按記載所及。僅限於菲洲,菲列濱,南印度等熱带區域。今在南京發現,於地理分佈上實為一新記錄。此種團走子在羣體成熟之後,其體質细胞間,並無原生質線交相聯絡。無性羣體每含有二至六大小不同成對均置之無性幼羣體。幼羣體在脫離母體以前,往往含有第二代幼體。各種有性羣體,亦自無性母羣體中發達而成。雄性羣體,皆为橢圓形,而較其他羣體為小。雌性羣體中之卵或大配子约有十二至四十六。雙性羣體只含有二或三精原细胞,及十五至二十七卵或大配子。孤性生殖细胞在幼羣體内即發生。當最初五或六次分裂時,细胞雖增加,而幼胎並不長大。精原细胞经七次連續之均等分裂,而成一束一百二十八精子或小配子。 1. The albino mice were used for this study. The Golgi apparatus in the cells of the epididymis and the vas deferens of normal, starved, and refed animals were studied.2. The amount of the Golgi elements can be maintained by feeding, not only by the sex hormone.3. The Golgi apparatus may be regarded as a product of food assimilation, not a definite cell organ.4. It is suggested that the Golgi apparatus has similar organ with that of mitochondria and secretion granules, but with different quantity of lipoids. (1)本研究以白鼠为材料,就常态白鼠绝食及再餵之白鼠观察其副睾丸及输精管上皮细胞内之高基體。查得在绝食期内副睾上皮细胞之高基體逐渐減少,由网状體变为颗粒,先集于前端後卽散开,至三十六小时高基體绝少,再餵後復有颗粒出现於前端。 (2)输精管上皮细胞内高基體原作线状,列於细胞前部。绝食十三时後,变为颗粒。俟三十六小时後再餵,卽有许多小粒在细胞前端边缘或卽係高基體 (3)由此结果可知高基體之多寡,既视绝食与否而定,或可谓为食物同化之产物,非固定之细胞器官也。 (4)高基體之起源或与粒线體,及分泌粒同,但其所含类脂質之量不同。 A solution of crystalline ribonuclease was injected intraperitoneally andintravenously into the blood stream of the mouse. A depletion of the ribonucleicacid together with a decrease of the calcium ash was observed in the corticalportion of the liver cell 12 minutes after the injection until recovery of normaldistribution 122 hours later. The possible association of calcium with ribonucleicacid in the cytoplasm constituents of the liver cell is discussed. 核醣核酸酶结晶体的溶液由腹膜腔或血管注射到活鼠的体内可引肝细胞皮质部分的核醣核酸的分解和钙质的消失。这种作用在注射後12分钟开始到124小时後肝细胞恢复常态。关於在活体肝细胞内核醣核酸和钙结合的可能性予以充分的讨论。
