ii TRANSLATOR'S INTRODUCTION. 



in 1749, his dissertation ' De Nexu Metaphysices cum Medi- 

 cina generatim/ In 1750 he published a ' Philosophical View 

 of the Human Body generally/ ^ in which the germ of his 

 future views may be distinctly traced. Towards the close of 

 this year he left Halle to reside at Hamburgh,^ where he im- 

 mediately became connected with the * Hamburgh Magazine' 

 (vide vol. vi), and communicated to it various essays of a 

 neuro-metaphysical character : amongst them was one, entitled 

 'Reflections on the fundamental Principle of StahVs Theory.'^ 

 In 1759 he established a weekly medical journal, ' The 

 Physician,'* on the model of Addison's ' Spectator,' with the 

 view of securing a proper estimate of physicians and of the 

 art of healing, and of extending sound medical knowledge, re- 

 moving prejudices, and checking the misdoings of ignorant 

 practitioners ; it is an amusing medley. The first part contains 

 his portrait by Tischbein. This journal was translated 

 into Danish, Swedish, and Dutch, and was published during 

 the years 1759-64; the neuro-psychological essays he inserted 

 in it are frequently referred to in the present work. From 

 1766 to 1769 he published ' Collections of Minor Physical 

 Essays :'^ and in the latter year, a new edition of ' Der Arzt,' 

 in six volumes. His portrait, taken in the 42d year of his 

 age, painted and engraved by H. G. Fritzsch, fronts the title- 

 page of the first volume. In 1768 he made an attempt at a 

 better and more systematic arrangement of his views, in a work 

 entitled ' Outlines of a System treating of the Sentiency of 

 Animal Organisms;'^ and, finally, three years after, he pub- 

 lished the work now translated, which he dedicated to his brother. 

 Dr. J. C. Unzer, and which may be looked upon as a new 

 and much improved edition of the last-mentioned publication. 

 Thus his 'Principles of a Physiology of the Animal Nature pro- 

 per to Animal Organisms,' was given to the world at the mature 

 age of 44, after it had been virtually a quarter of a century 



* Philosophische Betrachtung des Menschlichen Korpers uberhaupt. 1750. 



^ Haller makes a statement in his ' Bibliotheca Anatom.,' (vol. 2, p. 400), which, 

 on careful inquiry, I find to be erroneous, namely, that Unzer was Professor of 

 Medicine at the University of Rinteln.
