How TO Photograph Microscopic Objects. A Manual 

 for the Practical Microscopist. By I. H. Jennings. New York : 

 E. & H. T. Anthony & Co. Pp. 32. (Illustrated.) 



" The following pages are presented to the practical micro- 

 scopist as one of the best collections of useful information on 

 photo-micrography that has appeared for many years. The 

 author's standing amongst English scientific workers is a 

 sufficient guarantee for the thoroughness of the methods and 

 processes described, and we feel that American laborers in the 

 same field will find them an invaluable aid in this interesting 

 department of applied photography." — Publisher s Notice.
