PROCEEDINGS OF SOCIETIES. 
Mills, Esq., of Buffalo, three specimens of filterings from Niagara 
Kiver water, accompanied by a brief but interesting account of what 
they contained. For all which a hearty vote of thanks was passed. 
The President, Dr. Cutler, read an account of the microscopical 
examination of a pathological specimen sent the Society from a 
neighbouring city. The case seems in many respects a remarkable 
one, baffling the best medical skill. And the microscope, although 
demonstrating that the disease was not cancer, as was supposed, fails 
to discover its exact nature, A paper was also read from J. E. Smith, 
Esq., of Ashtabula, Ohio, giving the measurement of all the numbers 
on the MoUer Probe-Platte, as made by Professor Morley, of Hudson, 
Ohio, and compared with his own observations. Letters of ac- 
knowledgment were also read from T, W. Starr, Esq., and Henry 
Mills, Esq. 
The President then read his paper on the microscopic examina- 
tion of water from a pond, "Happy Hollow," of yellow fever notoriety. 
In this water he found a number of curious and interesting species of 
infusorial life, and several new and hitherto undescribed forms. This 
water proved so rich in life that a description of all it contains could 
not be condensed within the limits of one paper, and a portion is 
reserved for a future meeting. 
A vote of thanks was then tendered the President, after which the 
Society adjourned until the next regular meeting, February 4. 
San Francisco Microscopical Society. 
The annual meeting of the San Francisco Microscopical Society 
has been held some time since, but the report has only now reached 
us, and it seems it was well attended by resident members, and the 
reports of its various officers show a thriving and energetic state of 
affairs. 
Mr. Hanks, who has been President of the Society since its 
organization, read a very full and complete paper, giving a brief 
history of the Society, showing what had been done by the members 
during the past year, and which contained many valuable suggestions, 
extracts from which we give a place below. 
The report of the Treasurer, Mr. Ewing, was very satisfactory 
indeed ; and the assets of the organization,|in the way of instruments, 
library, furniture, objects, &c., with the cash on hand, show what a 
few determined ones can do when they are in earnest. 
After the reading of reports, the election of officers for the 
ensuing year took place, resulting as follows : President, Wm. Ash- 
burner ; Vice-President, H. C. Hyde ; Eecording-Secretary, C. Mason 
Kinnie; Corresponding-Secretary, Charles ^W. Banks; Treasurer, 
Charles G. Ewing. 
Louis Bene Tulasne, of Paris, was elected a corresponding member 
of the Society. 
Mr. J. P. Moore donated a pamphlet entitled ' New Mexico,' which 
was valued as containing a list of hot springs in that country, and 
from which he hoped to present, from time to time, samples of animal
