O04 The West American Scientist. 
Dr. James, who is attending the convention of the Americar 
Pharmaceutical Association in this city is well known to all mi- 
croscopists by his able contributions to this branch of science. 
He gave an interesting account of a phenomenal class of cry- 
stals produced from salicine by the extreme cold method as dis- 
covered by him several years ago, and exhibited a series of 
slides with the polariscope, which were pronounced by all to be 
the most beautiful crystallizations ever seen, The process de- 
pends on bringing a saturated solution of salicine made with dis- 
tilled water in contact with cold below the freezing point, and Dr, - 
James’ explanation is, that the rapid congelation of the water in- 
terferes with the usual arrangement of the crystals, producing the 
wonderful series before alluded to, which are entirely unlike any ~ 
forms resulting from crystallization at the ordinary temperature. 
The proper manner of making white zinc cement and permanent 
oxydized enamels for ringing slides formeda portion of his inter- 
esting contribution to the meeting. 
H. M. Whelpley of the St. Louis Microscopical Club also 
addressed the society on the subject ot the microscope in its 
relation to pharmacy, pointing out the rapid progress being 
made in the detection of adulterations and the interest manifested 
- generally among pharmaceutists in studying the character and 
acquiring a correct knowledge of the crude constituents of the 
materia medica. 
Pond life was illustrated by numerous specimens of Ceratium 
longicornis, and the beautiful little organism, Artemia salina, or 
brine shrimp. Entomology was represented by prepared slides 
of the larva of several varieties of the Papilio family. 
Professor Hanks presented for examination a venerable edition 
of a work on Pharmaceutics published by Robert Lowell in 1661. 
Mr. Riedy donated a copy of Trembley’s work on fresh water 
Polypes, an exceedingly rare and valuable book, published in . 
1744. ; Cre Bates, RCG= SCG.
