added a much greater number, who have written 

 Jearnedly and extensively on the subject, did not 

 the hmits of this review forbid such an enumeration. 

 It would be improper, however, not to take some 

 notice of what has been done in this department of 

 medical philosophy by Lieutaud, Ferrein, and espe- 

 cially by Venel, of France -, by Cartheuser,SpieImann, 

 and Murray, of Germany; and by Hill, Lewis, Al- 

 ston, Cullen, and Darwin, of Great Britain. Of 

 these the work of Dr. Lewis, improved by Dr. Aikin, 

 that of professor Cullen, and particularly the Jp- 

 paratus Medicaminiim of professor Murray of Goet- 

 tingen*, are entitled to the largest share of esteem. 

 The late work of professor Barton, on the mate- 

 ria medica of the United States f, forms a very va- 

 luable addition to the knowledge before possessed 

 on this subject, and reflects high honour on its 

 learned author. From the extent of information, 

 the vigour of mind, and the ardent zeal by which 

 this American naturalist and physician is distin- 

 guished, we may hope for further investigations, and 

 richer discoveries of the medical treasures of our 

 country. 



* Professor Murray did not live to publish any thing on the 

 mineral or animal articles of the materia medica. Professor 

 Gmelin, of Goettingen, has published the Mineral Materia MediccC, 

 as a supplement to Murray's work 3 but he is not considered as 

 ^having done justice to the subject.

 has presented a body of information, and discovered an accuracy 

 and extent of learning, which might, without impropriety, have 

 made higher claims. It is pleasing to observe that this work is so 

 favourably received by the author's countrymen, that a second 

 edzVio/i was lately demanded, into which he has introduced con- 

 siderable additions and improvements.
