certain Ferns,” and gave an account of his examination of many species 
of the Filmy Ferns—Hymenophyllacee, Trichomanes, and Todea; in 
each of which these organs were wanting. The specimens had been 
prepared by both bleaching and double staining, and a selection from 
them were exhibited in the room in illustration of the paper. 
Mr. T. C. White called attention to a curious organ which he had 
frequently observed to be attached to the third segment from the tail 
of a species of marine Cyclops, and which until lately had been ex- 
amined without success as to the discovery of its use or nature. Re- 
cently, however, Mr. White had been fortunate in determining it to be 
a spermatophore, and had seen under a }-inch objective spermatozoa in 
active motion, which had just escaped from a crushed specimen under 
examination. 
The attention of the members was particularly requested to the 
arrangements made for the soirée of the club to be held on April 13, 
and the meeting closed with the usual conversazione. 
Ordinary Meeting, April 27, 1877.— Henry Lee, Esq., F.LS., 
President, in the chair. 
Four new members were elected, ten gentlemen were proposed for 
membership, and a number of valuable additions to the library and 
cabinet were announced. 
Communications were read—from Mr. Bridgman respecting a new 
tinted glass which he had been successful in obtaining, and concerning 
which it was hoped that additional particulars would be furnished at 
a future date; also from members of the Excursion Committee, giving 
short and interesting reports of the field excursions of the club to 
Barnes on March 24, and to Snaresbrook on April 7. 
Mr. T. C. White read a paper on Botryllus, in which, after briefly 
enumerating the characteristics of the Tunicates, he gave the results 
of his personal observations on the life-history of specimens developed 
in his marine aquarium, the chief point of interest being the discovery 
of a method of progression which did not appear to have been previously 
noticed. The subject was well illustrated by drawings. 
Mr. Charles Stewart added some useful information as to the best 
methods of preparation, preservation, and mounting these organisms, 
and 
The President expressed a hope that Mr. White would continue his 
very useful investigations, and promised him such supplies of material 
from the Brighton Aquarium as his influence could procure. 
The proceedings terminated as usual with a conversazione, at which 
a number of interesting objects were exhibited.
