Cincinnati Medical News, January, 1889. " Wolff's Chemistry.- -A little 

 work that can be carried in the pocket, for ready reference in solving difficult 

 problems." 



St.. Joseph's Medical Herald, March, 1889. "Dr. Wolff explains most 

 simply the knotty and difficult points in chemistry, and the book is therefore 

 well suited for use in medical schools." 



Medical and Surgical Reporter, November, 1889. "We could wish that 

 more books like this would be written, in order that medical students might 

 thus early become more interested in what is often a difficult and uninterest- 

 ing branch of medical study." 



Registered Pharmacist, Chicago, December, 1890. " Wolff 's Chemistry." 

 " The author is thoroughly familiar with his subjects. A useful addition to 

 the medical and pharmaceutical library."
