Age and growth of Sebastes schlegeli collected from the coastal waters of the Shiribeshi subprefecture in Hokkaido were studied. Observations of the otolith margin verified that annuli (outer margins of the opaque zone) were formed chiefly in June. This period accorded approximately with the parturition season (late May-mid-June) that was judged from the seasonal change in gonadosomatic index, occurrence of eyed eggs and histological observations of ovaries. The surface method of otolith aging was found to be inadequate for aging of S. schlegeli older than 7 years because of the underestimation of age. A significant difference was found in the parameters of the growth equations between females and males. Growth of S. schlegeli was expressed by the von Bertalanffy asymptotic growth function as TLt=633.1(1-exp^[-0.160(t+0.965)]) for females and TLt=417.7(1-exp^[-0.363(t+0.368)]) for males, where TLt is the total length (mm) at age t (after parturition in years). Based on previously published data, the growth rate of S. schlegeli in this region was relatively low, especially in males, because of low temperatures during the winter and spring and the shortness of the high growth period of 10-20℃.

This paper probes which kinds of educational institutions developed from schools in the miscellaneous category into junior high schools by analyzing the current of secondary education in the early years of the Meiji Era Tokyo. In the first decade of the Meiji Era, private schools teaching the study of Chinese classics were predominant over those giving Western study. However, the trend gradually turned from the former (""classical knowledge"") to the latter (""modern knowledge""), as national institutions of higher education attached importance to modern knowledge in their entrance examination. In this situation some schools that offered modern knowledge and preparatory education for the entrance examinations developed into junior high school. And many aspirants desiring social success left their hometowns for Tokyo, especially such the schools, to acquire the knowledge. In conclusion this paper proposed that the strong point of the schools played a key role as centripetal force of modem Tokyo
