 Chemistry in the University of Edinburgh. 



One Vol. 12mo, 9s. 6d. cloth. 



" Dr. Gregory, Professor of Chemistry at the University of Edinburgh, 

 and the translator of Reichenbach's Researches on Magnetism, has just 

 published a volume destined, we believe, to excite considerable attention,- 

 both from the nature of its subject and the position of the writer.' 1 — Notes and 

 Queries. 



" One of the most exciting and absorbing volumes we ever read." — Non- 

 conformist. 



"No possible objection can be fairly taken to the mode in which Dr. 

 Gregory lays down his position and maintains his arguments ; and in our 

 humble opinion he has fully achieved his purpose of proving that there are 

 facts associated with what is termed Animal Magnetism, which merit the 

 careful and systematic study and investigation of scientific men and of 

 philosophers."— Morning Post.
