GENTLEMEN, 



I beg leave to dedicate to you this edition of Dr. Cullen's 

 text-books on Physiology, Nosology, and the Practice of Phy-

 Dr. Cullen's MS. papers, as seem to throw additional light on 

 the subjects of which these books treat ; and, secondly, to put 

 the public in possession of documents that appear to me to es-

 edition, and illustrated in some parts with Dr. Cullen's own 

 commentaries, in the belief that they are less generally known

 the edition published by Dr. Cullen in 1784, with the omis- 

 sion only of the abridgment which he has given of the nosological 

 systems of his predecessors and cotemporaries. 



The Lectures introductory to the Course on the Practice of 

 Physic, now published for the first time, have been printed from
