Dr. J. E. Talmage, of Salt Lake City, Utah, said that it might 
perhaps be remembered that at the meeting of the Society in June 
1891 he exhibited some specimens of the Brine Shrimp, Artemia fertilis , 
from the Great Salt Lake, and he then called attention to the great diffi- 
culty of making satisfactory preparations for exhibition under the 
Microscope. It was suggested that the best medium might possibly be 
the lake water, and he had found that for unstained preparations an 
excellent method of preserving was the use of a mixture composed of 75 
per cent, of lake water, 10 per cent, of a solution of alum, 10 per cent, 
alcohol, and 5 per cent, of solution of corrosive sublimate. In this it 
was possible to mount the creature at once, as it spread itself out upon 
the slide in a manner which displayed all its parts extremely well. By 
examining the specimen exhibited under a Microscope in the room 
Fellows of the Society would see with what perfection this operation 
was performed by the shrimp itself. For staining purposes the living 
shrimp should be slowly transferred to brine of a less density than that 
of the lake until a proportion was reached of 1/4 brine and the rest 
fresh water ; it would keep in this for some time, and could then be 
killed and stained with eosin, which answered very well. Attempts to 
stain with Bismarck brown were reported to result in absolute failure. 
The photographs exhibited in the room showed the shrimp with great 
minuteness, and gave a good idea of the way in w r hieh it spread itself 
out. He had also brought to the meeting some specimens of the Oolitic 
sand from the Great Salt Lake. Some of this was shown under one 
of the Microscopes on the table, and he had also with him a quantity of
