PROCEEDINaS OF SOCIETIES. 
tional testimony is useful and interesting to all students in micro- 
scopy ; and Mr. H. C. Hyde, Vice-President of the Society, who has 
given the mechanical features of the microscope in their adaptability 
to test objects a large amount of his attention, was called upon to 
make some remarks on the subject. Using the black-board and accom- 
panying his statements by the reading of a paper by J. Edwards 
Smith, of Ashtabula, 0., published in the microscopical department 
of the ' Cincinnati Medical News,' Mr. Hyde was able to so explain 
the matter as to interest and instruct all present. 
Mr. Munch exhibited some fine drawings from the microscope, of 
various minerals and rock sections, which were peculiarly beautiful 
and valuable for their accuracy and detailed finish. 
Mr. Hanks exhibited a binocular microscope which he had caused 
to be made from a pattern of his own, and a number of which he had 
imported for miners and mineralogists. The want of such an instru- 
ment has long been felt, and the combination of its many features, in 
the way of portability, movements, and cheapness, were noted satis- 
factorily. 
Mr. W. H. Pratt, corresponding member, donated four slides, 
mounted by him with the anthers and pollen of sweet elysium, pollen 
from the osage orange, fly's foot, and fine gold. 
Dr. J. W. Winter donated two slides with objects, prepared and 
mounted by him in balsam, being a longitudinal and transverse section 
of human cuspidata, showing very clearly the enamel, dental tubulars, 
cementum, and periosteum. 
Mr. Henry Edwards, honorary member, donated two specimens of 
the Dytiscus marginalis, from Europe, and which is a favourite object 
with microscopists for the tarsi ; also a great variety of material, for 
examination and mounting, in the way of insects. 
Mr. C. G. Ewing donated a slide, mounted with a microscopic 
barnacle in glycerine taken out of a shell, found on the bottom" of the 
steamship ' Vasco de Gama.' 
Perhaps the most valued acquisition for future research is that of 
the donation by Mr. Fisher, of the U.S.S. ' Tuscarora,' of samples of 
a series of twenty-three deep-sea soundings from Cape Flattery to the 
Aleutian Islands, and of twenty-six from San Diego to Honolulu. 
These have been arranged, numbered, and labelled, with statistics 
regarding latitude, longitude, depth and temperature, in each case, by 
Dr. H. W. Harkness, assisted by Messrs. J. P. Moore and Kinne, and 
form a field for study for months to come. 
After the exhibition by Mr. Hyde of a series of very beautifully 
and wonderfully arranged slides, particularly one, which was a picture 
made up of butterfly scales, arranged as a bouquet of flowers in a vase 
of diatoms, &c., with two birds, lizard, and various insects, mounted 
by Dalton, London, the meeting adjourned. 
The stated meeting was held at the Society's rooms, Thursday 
evening, March 18, with President Ashburner in the chair, and a fair 
attendance of resident members. Dr. Eisen, corresponding member, 
and Mr. W. A. Skidmore, visited the rooms. 
Two proposals for resident membership were received, and Henry 
Molineaux, Esq., was elected as such.
