While we are pained to record the death of such an earnest 

 worker as Dr. John Frey, of New York, yet to the older lovers 

 of microscopical science will the announcement bring especial 

 sadness. For over forty years Dr. Frey was actively engaged 

 in the study of those things revealed by the microscope. At 

 the time of his death, which occurred on the 4th of Dec ember 

 last, he was Vice-President of the Microscopical Society of 

 New York City, and General Superintendent of the dispensing 

 department of Bellevue Hospital. 



Tennyson Calendar.

Odontology. By Prof. C L. Ford, M. D., D. D. S., LL. D., Professor 

 of Anatomy and Physiology, Univ. of Mich. 



Professor Ford presents in these fifty pages a vast amount 

 of knowledge on the development and structure of teeth, hu- 

 man and comparative. The work is arranged mostly in the 

 form of questions, and thus becomes a valuable addition to this 

 author's well-known series of " Questions." Any student, with 

 this book for an aid, with access to the large illustrative collec- 

 tions of Prof. Ford, and with his oral instructions, who fails in 

 Odontology, is surely non compos mentis. 



Among our most liberal advertisers is the firm of Reed & 

 Carnrick. The attention of our medical friends is called to 

 their advertisement of cod-liver oil and milk. The oil has been 

 artificially prepared for assimilation with pancreatine, and even 

 the milk has been thoroughly digested as well. It is a great 

 advance upon previous productions for similar purposes, and we 

 believe it to be greatly superior to any preparation of cod-liver 

 oil now in the market. They have, as they deserve, the unani- 

 mous support of the medical profession.
