he had no strong opinion as to whether this question of what a 
species is could or could not be answered, but he felt sure that to 
_ take Professor Williamson’s suggestion, and merge some ten or 
twenty of these forms of marine Entomostraca into one species 
would be to make it impossible to form even a conjecture of what 
is meant by that term. 
TRE Qupxett Microscopican Cus. 
Under this name a new club has started in London. The 
following manifesto of the nature and objects of this new Society 
has been issued: 
“This club has been established for the purpose of affording to 
microscopists, in and around the metropolis, opportunities for 
meeting and exchanging ideas without that diffidence and con- 
straint which an amateur naturally feels when discussing scientific 
subjects in the presence of professional men. 
“The increased study of natural history during late years has 
created a large class of observers, who, although with limited 
leisure for such pursuits, possess notwithstanding earnestness of 
purpose, and ability to render good seryice in the cause of micro- 
scopical investigation. 
“The want of such a club as the present has long been felt, 
wherein microscopists and students with kindred tastes might 
meet at stated periods to hold cheerful converse with each other, 
exhibit and exchange specimens, read papers on topics of interest, 
discuss doubtful points, compare notes of progress, and gossip 
over those special subjects in which they are more or less in- 
terested ; where, in fact, each member would be solicited to bring 
his own individual experience, be it ever so small, and cast it into 
the treasury for the general good. Such are some of the objects 
which the present club seeks to attain. In addition thereto it 
hopes to organize occasional field excursions, at proper seasons, 
for the collection of living specimens, to acquire a library of such 
books of reference as will be most useful to inquiring students ; 
and, trusting to the proverbial liberality of microscopists, to add 
thereto a comprehensive cabinet of objects. By these, and similar 
means, the Quekett Microscopical Club seeks to merit ‘the support 
of all earnest men who may be devoted to such pursuits; and, by 
fostering and encouraging a love for microscopical studies, to 
deserve the approval of men of science and more learned societies. 
“The ordinary meetings of the club will be held on the fourth 
Friday of every month, at 8 o’clock in the evening, at No. 32, 
Sackville Street, Piccadilly. 
“Tn order to place the advantages of this club within the reach 
of all, the annual subscription has been limited to ten shillings, 
payable i in advance, on the Ist of July in every year. 
«Gentlemen desirous of becoming members are informed that 
no entrance fee is demanded, and that the Secretary will furnish
