Mr. E. B. Green exhibited his drawings of the root hairs of 

 plants and their so-called parasites, all drawn to a uniform scale of 

 1 5.°, and explained the peculiarities observed. 



Mr. Karop thought that the question as to whether the green 

 colour referred to in these bodies was chlorophyll could readily be 

 settled by the spectro-microscope, since the characteristic bands of 

 that substance were easily recognized. It seemed so exceedingly- 

 doubtful whether chlorophyll was ever formed quite beyond the 

 influence of light that it was very desirable to ascertain whether 

 what Mr. Green thought was that substance really was so or 

 whether these bodies were simply some green unicellular algEe or 

 spores washed into the ground by rain. 



The President thought the subject was full of interest and 

 opened up many new lines of research, and he hoped one result of 

 Mr. Green's communication might be that some of their members 

 might feel interested in the questions raised, and start for them- 

 selves on some of these investigations. 



The thanks of the members were, on the motion of the President, 

 voted to Mr. Green. 



The President mentioned that he had after many attempts suc- 

 ceeded at length in resolving some very minute structure on 

 Navicula major. 



The thanks of the meeting were voted to the President for his 

 interesting communication. 



Announcements for the ensuing month were made, and the 

 meeting terminated with the usual conversazione.
