452 BOTANICAL GAZETTE [ DECEMBER 
THe Bauscu & Loms Optica. Co. announce their intention to begin the 
publication, on January 1, of an octavo sixteen-page monthly periodical 
devoted exclusively to the science involving the use of the microscope, par- 
ticularly in the line of practical methods of working, the description of new 
apparatus and the recording of new uses for already described appliances, 
new and useful formule for staining, fixing, mounting, etc., news about 
prominent men and institutions both domestic and foreign, correspondence 
and criticism and current literature. The paper and printing are to be of the 
best, and accurate illustrations will be provided when required. 
It is proposed to conduct this journal in the most conservative manner as 
to the accuracy and practical value of the matter. As there is at present no 
publication in this country devoted to the above mentioned subjects exclu- 
sively, the company has been repeatedly urged to establish and maintain 
such a periodical. They hope to receive the hearty support of all interested 
in the advancement of science.
