An account of Mr. W. West’s paper “ On the Freshwater Algse of 
the English Lake District” was given by Mr. Bennett, who said that, 
although the paper was in itself too technical to bear reading at the 
meeting, it formed an exceedingly important contribution to their know- 
ledge of the algae of this country, and would add greatly to the value 
of their Journal by its publication. The list given comprised a very 
large number of new species, and one new genus — Tetracoccus — which 
he thought had every right to be so considered. He had himself, as 
they knew, found a great many new species in the same localities, and 
it was a strong testimony to the thoroughness of Mr. West’s work to find 
that every one of these species was included in his list. 
The President thought that a paper like the one before them showed 
how great was the value of the instrument with which they were accus- 
tomed to work, and also that Mr. West must have an extraordinary eye 
for detecting these organisms, many of which were so very minute in 
character. 
Mr. F. Chapman gave a resume of his paper, being Part 3 of his 
description of the Foraminifera of the Gault of Folkestone, the pre- 
ceding portions of which have already been published in the Society’s 
Journal. 
Mr. C. Haughton Gill read his paper “ On a Fungus internally 
Parasitic in certain Diatoms,” the subject being freely illustrated by 
reference to a number of specimens under Microscopes in the room and 
by photomicrographs placed in the hands of the Fellows for examination. 
At the conclusion of the paper the subject was further illustrated by the 
exhibition on the screen of a series of photomicrographs, which, begin- 
ning with a healthy specimen of Pleurosigma , showed in succession 
others which were infested with the fungus in various degrees; an 
isolated spore-sac X 400 was also shown, and, in addition, two speci- 
mens of Nitzschia and one of Cocconema similarly affected. 
The President felt sure that all present would agree that a hearty 
vote of thanks was due to Mr. Gill for his paper, and for the excellent 
way in which it had been illustrated. He should like to ask if these 
specimens had been observed in many localities, or were they peculiar 
to one? 
Mr. Gill said he was unable to say whether the fungus was widely 
distributed, because, personally, his opportunities for collecting were very 
much restricted to one collecting place — the New River. There, how- 
ever, diatoms could be got by the ounce. Though the gatherings contained 
examples of the greater number of British freshwater species, those which 
he had mentioned were the only ones in which the fungoid growths had 
been found. 
Mr. G. C. Karop thought Mr. Gill had certainly given them a very 
excellent paper upon what appeared to be the first observations made in 
this country upon these remarkable fungoid growths. He thought that 
Zopf mentioned that he had found them also in Pinnularia , and he had 
also remarked that at different times they seemed to prefer different 
diatoms.
