ART. 3. — SEIICHI KAWAMURA : 



internal parts appeared lnminous, but the surface had not recovered 

 luminosity, on which account the entire object was but faintly 

 luminous. It seemed that the surface which had been in direct 

 contact with the warm water had permanently lost the luminosity. 



(f) 47°C. Placing the fungus in the water of 47°C, the light 

 commenced to fade after two seconds and became invisible after 

 ten seconds. The specimen was then restored to the air, but did 

 not recover luminosity. 



(g) 6(FC. As a specimen was thrown into the water of 60°C, 

 the light immediately began to grow weaker, and became invisible 

 after five seconds. Though it was then quickly taken out of the water 

 and exposed to the air, the luminous power was irrecoverably lost.
