74 PROCEEDINGS OF SOCIETIES. 
Certificates in favour of seven candidates for election into the 
Society were read, and ordered to be suspended in the usual 
manner. 
Dr. Braidwood, Carlisle; Thos. Croak, Esq., Thames Ditton ; 
C. W. Calthorp, Esq., Alford; Thos. Curties, Esq., 244, High 
Holborn; Chas. Davis, Esq., 14, Wimpole Street; Rev. J. H. 
Ellis, Thame, Oxon; Dr. Gray, 23, Princes Street, Cavendish 
Square; R. T. Lewis, Esq., Lowndes Terrace, Knightsbridge ; 
Wm. Maguire, Esq., 35, Queen Square; and W. C. Pickersgill, 
Esq., Bexley, were balloted for, and duly elected Fellows of the 
Society. 
The SrcreTary communicated to the Society the following 
letter from Mr. Carruthers, of the British Museum : 
“Tt would be well that the Fellows of the Microscopical 
Society should know that the type specimens of all Greville’s 
Diatomacee, figured in their ‘Transactions,’ are now deposited 
here, and that the collection includes not only Greyille’s own 
slides, but also those prepared by the late Professor Gregory, 
some of which were described and figured also in the ‘ Transac- 
tions’ of the Microscopical Society. These, added to the type- 
collection of Professor W. Smith, who monographed the British 
species, make our collections here invaluable as an authoritative 
series of the British Diatomacez.”’ 
The following papers were read :—“ On a new Condenser,”’ by 
Rey. J. B. Reade ; “ On two newSpecies of Tube-bearing Rotifers,”’ 
by H. Davis, Esq. 
A series of photographs from Major Woodward, of America, 
was exhibited by Mr. How. 
The thanks of the meeting were voted to these gentlemen for 
the same. 
“Wire-Spring Clip for Microscopic Mounting.”—Mr. Jabez 
Hogg exhibited a wire-spring clip for holding 
down the covering-glass when preparing micro- 
scopic objects. It is shown in the accompanying 
figure in use. A clip somewhat similar was de- 
vised by Dr. Maddox; this, however, is a decided 
_ improvement, and is made by bending an elastic 
brass wire, so that it will open and shut like the 
common letter-slip. The cover is pressed down 
by the small cork, or, what is better, a thick 
pledget of leather (seen in the figure), and held 
in its place while cement is applied or allowed to 
dry, or Canada balsam allowed to insinuate itself 
by capillary attraction. Mr. Jabez Hogg stated that he had 
found them extremely useful, and that Mr. Baker is selling them 
at a very small price per dozen.
