Mr. Miyake studied the structure of the sperm at ozoicl of Mahinoa 

 crispaia (a new genus and species recently described by him) which he claims 

 to be the largest spermatozoid among Bryophyta. He used fuchsin-iodine 

 green for the stain and proved the correctness of the last view. Some 

 remarks on the newly discovered spermatozoid of Gymnosperms were made. 

 The presence of clearly differentiated nucleus in these spermatozoids was 

 considered to give another proof of the correctness of the current view. 



Prof. S. Tanaka in his paper " The Relation of Botany to Agricultural 

 Science " emphasized the intimate relationship of the two. He said that 

 Agricultural Science, being a newly born one, must be aided by the various 

 branches of Science, among which Botany should first be mentioned. The 

 relation of the nourishment of plants to the composition of soil and 

 manure, utilization of the waste products, etc., owe greatly to the investiga- 

 tion of modern Botany. As an example he called our attention to the 

 discovery of the nitrogen fixing organisms in the tubercles of the leguminous 

 plants, and their utilization in agriculture. He also emphasized the 

 pressing need of the botanical investigation from its agricultural point 

 of view. 



Mr. S. Hori reviewed his researches on " Two Kinds of Diseases 

 in Solanum Melongena." Solanum Melongtna suffers from two kinds 

 of diseases — one caused by a mould called Phusalium solani, other by a 

 bacteria, Bacillus solanaciarum. The former was already noticed by Prof. 

 Miyabe of Sapporo, and Mr. Hori made more minute study on the latter. 

 The pure culture of the Bacillus was made on the gelatine. Each Bacillus 

 is short-rod-like in shape, and by using methyl-violet, both ends takes the 

 stains, while the middle portion remains uncolored, thus it looks like a 

 diprococcus. The Bacteria are abundantly found in the soil of the farms. 

 The infection experiments were also made. He called attention to the 

 similarity of the Bacillus to the one described by Mr. Smith in his recent 

 paper " A Bacterian Disease of Tomato and Solanum." For protection 

 from this land of disease he recommended to cover the base of the stem 

 with ash. 



Mr. K. Fujii read a paper on " Direct Nuclear-division in Plant-cells." 

 The direct nuclear-division or amitosis has been found mostly in the old 

 degenerating cells. So it was held by the leading cytologists such as Fleni- 

 ming, Tiegler, Vom Rath, &c., that this is rather a pathological phenomenon 

 accompanied by the degeneration. Strasburger, Waldeyer, and others con- 

 sidered it to be a primitive stage of the cell-division. It was also know r n that 

 amitosis occurs in the hypertrophied tissues caused by the attack of fungi.
