November 4, 1882. Mr. E. S. Bowler writes me that he obtained 
one taken in Penobscot county, Maine, January 15, 1882, and 
two taken in the same county January 23, 1883. Two were 
taken near St. John, N. B., and sent to that city February 17, 
1882. Mr. C. A. Creighton has informed me of one taken at 
Waldoboro’, Me., in January, 1881. And I am indebted to Mr. 
Ralph Miller, of Portland, Me., for a specimen taken by him alive, 
x hand, in this city, March 3, 1883.—£veredt Smith, in Forest and

White Beavers.—When at Olympia, Washington Territory, 
in June, 1882, my attention was called to a mounted specimen of 
a beaver, an albino, belonging to Mr. E. T. Young, of that place. 
It was clearly and absolutely white throughout, without the least 
tint of the usual color, and in fine condition. I learned from the 
ZooLocicaL Nores.—Protozoans.—Gigantic specimens of Actin- 
Spherium eichhornii have been noticed by Professor Leidy in an 
aquarium; they measured 3-1™ in diameter, independent of 
€ rays, which extended from %-%™™ more. One o the 
smaller individuals contained four water-fleas (Daphnia), and one 
of the larger six of them. 
‘ng experiments by M. H. A. Coutance. The experimenter pre- 
Pared eight solutions containing one ingredient only, and three 
™ which chloride of magnesia, chloride of potash and sulphate 
Magnesia respectively predominated instead of chloride of 
M. ‘um. The mollusks experimented upon were Venus reticulata, 
Jtlus edulis, Venus decussata, Littorina vulgaris and Tritonium
