THE MiIcROSCOPE. 311 
The library was augmented by a number of valuable works 
on optics and microscopy, while the cabinet was enlarged by a 
series of mounted slides, mounting material and miscellaneous 
accessories, a gift from the society’s late associate, F. L. Howard. 
The donation was accompanied by a letter from Mrs. Howard, 
setting forth the wishes of the departed member. The collection 
will be known as The Howard Memorial. 
Mr. Wickson presented a collection of Diatoms in situ, a don- 
ation from Prof. George Davidson of the United States Coast 
and Geodetic Survey. They come from the northern end of Lopez 
Island, in Washington Sound, W. T., and will form a valuable 
addition to the society’s working material. The Diatoms were 
accompanied by a sample of supposed diatomaceous earth found 
near Santa Rosa. HK. H. Griffith of Fairport, N. Y., one of the 
society’s corresponding members, donated a beautiful series of 
mounted slides, illustrating the gorgeous Diamond beetle or 
Eupholus Linnei. The glittering scales covering the body of this 
member of the weevil family form one of the most brilliant ob- 
jects that can be presented to the eye. 
C, C. Riedy exhibited a large collection of mounted Diatoms 
from the hand of the noted specialist in that line, C. L. Peticolas. 
A slide prepared by that gentleman from the recently discovered 
Redondo Beach earth found some miles south of Santa Monica, 
is thought by him to be fully equal to the celebrated piece dis- 
covered at Santa Monica several years ago, and published to 
those interested in this branch of microscopical research by the 
investigations of the late Prof. William Ashburner, Another 
remarkable slide in the collection exhibits what is known as 
the Eighth-street Tunnel diatomaceous deposit of Richmond, Va., 
one of the finest deposits of strewn Diatoms ever found. The 
slides of fossil marine Diatoms from Syzrap, Russia, and Kekko, 
Hungary, are also notable for the variety of their forms and the 
skillful manner in which they have been prepared before mount- 
ing. | 
F. W. Dunning of Battle Creek, Mich., forwarded a box of 
diatomaceous earth from Lyons creek, Calvert county, Md. The 
same gentleman also sent a sample of diatomaceous earth broken 
from a piece found by a fisherman some time in June last float- 
ing in the Pacific Ocean, about two miles off the coast of Santa 
Monica. The latter material will be examined and compared
