By examing the various thick herbaceous stems, roots, and rhizomes 

 of Rliaphanus Salivas, Aral i a cordata, Allium fistulosum, dec, which may 

 "be naturally regarded as artificially hyperotrophied by the cultures, he found 

 that the amitosis is also taking place there. Whether the amitosis is to 

 be ascribed to degeneration or to hyperotropny, or to some other unknown 

 causes, it should be determined by the farther investigations. 



Mr. K. Aso presented the result of his " Analysis on the Spore of 

 Aspergillus Orizae." The quantities of water, albumen, fat, alcoholic ex- 

 tract, and ashes were shown by tables. He found a large quantity of 

 mannite in the alcoholic extract. And the comparatively richness of iron 

 in the ashes was specially noted. He also made some remarks on the 

 existence of calcium in the ashes. 



Mr. S. Kusano in his paper on " The Parasitic Plants," after discussing 

 the origin and significance of Parasitism in the plant world, made more 

 detailed remarks on the Phanerogamic parasites. There are many degrees 

 of graduation in parasitism, from the chlorophyll-less Lathrea to the green 

 Viscum which is said to get. only water and inorganic salts dissolved in it, 

 from the host-plant. Their physiology and biology must be very interesting. 

 The principal results of recent investigations on phanerogamic parasites 

 were thoroughly reviewed. He made some remarks on the phanerogamic 

 parasites found in Japan, and on the interest and value of their physiological 

 and biological studies. 



At 2 p.m. all the members were requested to take picture together ; 

 and soon after the business meeting was held. After the report of a sec- 

 retary, following officers were elected for the ensuing year : President, Prof. 

 J. Matsumura ; Secretaries, T. Inui, S. Yoshizoe, and K. Miyake. 



At 3 p.m. the reading of the papers was begun again. 



Mr. H. Hattori read a paper on the " Reaction of Copper sulphate on 

 Resin." Reaction of copper acetate on resin was already known as " Un- 

 verclorbene Franchimont Reaction." By soaking the stem and leaf containing 

 resin in the solution of copper acetate for about a week, the deep green 

 color is aquired by the resin. The same thing was observed with copper 

 sulphate, using 5-10 o/ or more concentrated solution. Thin sections of a 

 specimen thus treated, give very beautiful preparations for the resin-duct. 

 The materials used were the stem and leaf of Pinus Thunbergii and P. 

 densiflora. Whether the similar reaction is also to be observed in the resin 

 of other conifers is a question to be determined by further studies. If 

 the leafy stem of a pine is thrusted into the copper sulphate solution for 

 some time, the salt is taken up by the transpiration stream and gives
