Prof. O. W. Morris read a 
REPORT ON METEOROLOGY FOR THE MontTH oF May, 1870. 
He showed that the Barometer had been highest at 9 A. 
M. on the 18th, when it reached 30-245 inches; and lowest at 
7 A. M. on the 7th, when it was 29°356 inches. The monthly 
rain had been 889 inches. 
The Thermometer was highest at 2 P. M. on the 16th, when 
it stood at 83° F., and lowest at 7 P M. on the 11th; when it 
was 47° F. These observations were taken under the North-

the sun never reached. The warmest day was the 16th, when 
the mean temperature was 75°16 F., and the coldest the 11th, 
when the mean temperature was 47°50 F. There had been 
rain on 17 days and the depth was 3.08 inches. There were 
six thunder showers during the month. 
Prof. A. M. Edwards read the following paper: 
ON THE PREPARATION OF SPECIMENS OF SOUNDINGS FOR 
THE MICROSCOPE. 
In the course of his gatherings it not unfrequently hap- 
pens that the microscopist acquires specimens of the bot- 
tom of the ocean, from various localities, which, if properly 
prepared furnish him with many beautiful objects for observ- 
ation and study. And the beauty of these objects, the 
remains of once-living organisms, are of such a marked char- 
acter and present so many points for admiration that even to 
the unscientific observer they become sources of pleasure often 
leading to farther enquiry into their life-history, so that im- 
perceptibly almost and by gradual degrees the possessor 
becomes a student in fact and is induced to follow up lis in- 
vestigations to some practical end. 
At the present time such specimens are of especial interest 
on account of the remarkable revelations made by the deep-
