The Chairman made some observations in praise of the 
plan, which he had no doubt would be productive of advan- 
tage and add to the interest of the meetings of the Section. 
It was suggested by Mr. Brothers that a special subject, 
previously fixed upon, should be discussed at each meeting : 
the suggestion was at once adopted. The subject for discus- 
sion at the next meeting will be, “ Upon the Best Method 
of Preparing and Mounting Diatoms, &c., obtained from 
Soundings and other Sources.” It is requested that the 
Members of the Section will meanwhile obtain and communi- 
cate all the information they can on the subject 
Mr. Lynde exhibited a specimen of a small insect allied to 
the Podura, which he found leaping about on the surface of 
the water in his aquarium. Mr. Lynde had never seen a 
description of such an insect, nor was it known to any of the 
Members of the Section present. 
Mr. Brothers exhibited the hydra viridis, &c. 
A few specimens and parts of flowers obtained at the 
Botanical Gardens, were exhibited by the Secretary. In 
the tank of the Victoria Regia, little minute animal life could 
be discovered during a short visit. A specimen of Cetochilus 
was shown which was found there, as also a few diatoms not 
fully examined.
