then put on a slide, the shaven side up. A drop or two of clean 
water, and a cover glass of medium thickness, with good illum- 
ination follows, Mr Devoe using a prism illuminator. Begin 
with a six-tenths inch objective, and continue to a sixth or a 
tenth, and a vision is got of a startling clearness. The vivid 
individuality of each bieplasmic molecule, and the mystic, 
almost solemn movement of this pellucid stream of infinities of 
life, form a sensational picture of which the beholder never tires. 
NOTES FROM THE AMERICAN SOCIETY OF MICROS- 
COPISTS. 
T. J. BURRILL, SECRETARY. 
HE twelfth annual meeting of the American Society of Mic” 
roscopists convened August 20th, 1889, in the rooms of the 
Natural History Society at Buffalo, New York. The place of 
meeting proved in every way to be an excellent one for the 
Society, both in regard to the city and to the local quarters occu- 
pied. The local committees, under the general chairmanship of 
Dr Lee H. Smith, had everything magnificently planned and 
executed for the accommodation and well-being of the members, 
and for the work in hand. No society was ever more appropri- 
ately entertained, and no local committee ever did its duty more 
faithfully and effectively. 
The attendance of members was also encouraging and suffi- 
cient to make the meeting notable, though not the largest in the 
history of the Society. It was remarked that there were more 
past presidents in attendance than had ever before occurred. 
The register shows: seventy-six names, but there were a few 
present who did not place their names on the secretary’s roll. 
Twenty new members were elected. 
The papers and discussions were always itary and 
worthy, while some were of a higher order of merit as the 
printed volume will abundantly show. The list of titles is as 
follows: 
Geo. E. Blackham: “On the amplifying power of objectives 
and oculars in the compound microscope.” 
S. H. and 8. P. Gage: “Staining and permanent preservation 
of histological elements isolated by means of nitric acid and 
caustic potash.” 
Thomas Taylor: “ Detection of adulteration in tea.”
