Country ''Fellows" of the E-.M.S. — A correspondent asks why 
country Fellows, who are seldom able to attend the meetings, and to 
whom the library offers little advantage, should have to pay the same 
entrance fee and subscription as town " Fellows ? " The question is 
one for the Council to answer. 
Plumules of Moths. — We hope to give the second part of Mr. 
Watson's paper, with illustrations, in our next Number. 
A Handbook of British Fungi, which will include all known 
species, and will therefore deal with an important branch of micro- 
scopic research, is in preparation by Mr. M. C. Cooke, the well-known 
fungologist and foreign secretary to the Quekett Club. It will form 
one volume, small octavo, and will contain full descriptions of all 
known species of British fungi, with illustrations of the principal 
genera, and references to figures of the species. The price will be 
half-a-guinea to subscribers. The publication will be commenced as 
soon as the names of sufficient subscribers have been received to war- 
rant the undertaking. Communications should be addressed to Mr.

Mr. Collins' s Portable Microscope. — Mr. Collins has constructed 
a portable microscope which is especially intended for those who pur- 
chase some of his larger instru- 
ments. When packed it forms 
an oblong mahogany box, about 
6 inches long by 3 inches wide, 
and 2^ high. It may easily 
be carried in the great-coat 
pocket. It is difficult to ex- 
plain its construction, which is 
partly shown in the adjacent 
figure. The microscope body 
is attached to the inner side of 
the cover of the case. This 
cover, on being lifted up, is 
made to rotate on a central 
pivot, so that its inside is 
loosened out. The degree of

bar, which slides in a second one, and which supports the lid and can 
be clamped at any angle. The stage is small, and the mirror draws 
out from beneath it. The objectives and eye-piece are those of this 
maker's other instruments. We have done some work with this in- 
strument, and found it very handy, in the absence of our larger micro- 
A New Manipulator, by J. Howard Hooper. — There can be 
few microscopists who have not longed for some more ready and 
exact method of manipulation under the compound microscope than 
is afforded by even the steadiest and most practised hand ; and 
several instruments more or less complex have been devised and 
even patented for this purpose, but all have been constructed on the
