freshwater Polyzoa. He should be very pleased after the meeting to 
answer questions or give any information desired as to any special 
slide. 
The Secretary said they had received a paper by Mr. Millett in 
continuation of his former communication on the Foraminifera of the 
Malay Archipelago (see p. 258). It was no doubt a paper of value, but 
was highly technical, and as it would appear in extenso in the Journal, 
he hoped he should he excused from reading it to tho meeting. 
The paper was then taken as read. 
The President said that their hearty thanks were due to Mr. Priest 
for so kindly bringing down these very beautiful slides for exhibition. 
Their thanks were also due to Mr. Baker for the loan on that occasion 
of the number of Microscopes on the tables, by means of which it had 
been possible to show so large a number of objects. 
Votes of thanks to Mr. B. W. Priest and Mr. Baker were then put 
to the meeting, and carried with acclamation. 
The President reminded the Fellows present that the next meeting 
of the Society would not take place until October 19th, and wished them 
all a pleasant vacation.
