spent in visiting the Botanic Garden of the Imperial University and the 

 Botanical Institute found there. 



In the Botanical Institute many specimens and apparatus were ex- 

 hibited. Besides the dried and alcoholic specimens, many living ones were 

 shown. In a large table many representatives of diverse classes of plants, 

 from Myxomycetes to the higher Phanerogams were placed, majority of 

 which being cryptogams. The living specimens of the carnivorous plants, 

 both native and exotic, were very instructive. Alcoholic specimens of 

 Myrmecodia echinata, Hydrophytum montanum, the ant plants from Java 

 must have attracted much attention from the ecological point of view. 



Many instructive microscopical preparations were also shown, among 

 which there were the interesting spermatozoid of Ginkgo and well prepared 

 endosperm tissues of Strychnos Nux vomica showing the continuity of the 

 protoplasm between the cells. The spermatozoid above mentioned is some- 

 what oval in shape, having a large spherical nucleus and with no tail-like 

 appendage as once described by Mr, Hirase. 



Physiological apparatus, such as auxanometers, clinostats, and various- 

 apparatus for experimenting assimilation, transpiration and respiration 

 were liberally exhibited. Several simple experiments performed with these 

 apparatus must have been very instructive for teachers. Also many pure- 

 cultures of various bacteria and fungi, and the water- cultures of the 

 flowering plants were shown. The water-culture demonstrating the poisonous 

 effect of the copper upon plants very much attracted the attention of all. 



On 9 a.m. of the next day the meeting was held at the Botanic 

 Garden of the University. Prof. Matsumura, the president of the society, 

 presided. After the reports of the secretaries, some modifications on 

 the rule of the society were acknowledged. The following papers were 

 read. 



Mr. K. Miyake read a paper " On the Spermatozoids of Plants." He 

 first reviewed the different opinions hitherto presented regarding the structure 

 and development of the plant spermatozoid. They may be classified into 

 three. First and the oldest view is that the nucleus of the mother-cell 

 dissolves and fuses with the surrounding cytoplasm before the formation 

 of the spermatozoid, and from one part of the homogeneous mass of the 

 protoplasm the body of the spermatozoid begins to be formed. Second 

 view claims that the body of the spermatozoid is formed only from the 

 nucleus of the mother cell by direct transformation. Third and now pre- 

 vailing view is that the body of the spermatozoid is formed from both 

 nucleus and cytoplasm of the mother-cell.
