the students of the University ; and in the summer of 1804 he 

 delivered his first course of lectures on physiology, comparative 

 osteology, and the cranioscopy of Dr. Gall. 



Finding, however, that his own knowledge was still very defective, " 

 he again repaired, in the autumn, to Wiirzhurg, where, under Hessel- 

 bach, he occupied himself principally in the dissection of the nervous 

 system, attending at the same time ScheUing's Lectures on Natur- 

 PhUosophie, in which for a short time he hoped to find some new 

 basis for Natural History, and more especially for Medicine. But 

 inquiries of this transcendental nature seem always to have been 

 foreign to his eminently practical and realistic mind, and thirty years 

 afterwards he describes the only effect upon him of SchelHng's lucu- 

 brations in these words : — " By his brilliant but fantastic views of 

 the physical world, that great philosopher had himself removed from 

 me all temptation to abandon the road of empirical research and 

 observation." 



Inspired by an ardent desire to enter on this road, he determined 

 to proceed to Paris to consult the great collections there, and to 

 benefit by the teaching of the great men under whom they were 

 placed. 



In Paris, Tiedemann laboured assiduously in the Jardin des Plantes 

 and the Museum, and attended the lectures of Cuvier,Etienne Geoffrey 

 St.-Hilaire, Lamarck, Dumeril, and Haiiy. 



But he was recalled from Paris sooner than he had intended. In 

 1805, on the recommendation of Soemmeriug, he was appointed Pro- 

 fessor of Zoology and Anatomy in the University of Landshut, at the 

 early age of 25. Here he found abundant occupation ; for, although 

 he was installed in a new and beautiful anatomical theatre, it was 

 totally unprovided with preparations of any kind. He found nothing 

 in this way but a chest of bones and an Egyptian mummy ; nor had 

 he, moreover, any help in the supplying of these deficiencies, having 

 first even to instruct his prosector in the art of dissection. Thanks 

 to Napoleon, however, there were at that time plenty of subjects to 

 be had at Landshut, which was occupied alternately by French, 

 Bavarian, or Austrian troops, from whom the Anatomical Professor, 

 at any rate, was furnished with abundant supplies of bodies, amount- 

 ing probably on occasion to a superfluity, as after the battle of Aus- 

 terhtz, in which 15,000 Russian prisoners were taken, very many 

 of whom died on their transit through the town. Earnestly occu- 

 pied in his work, and surrounded with a circle of scientific friends, 

 his life passed usefully along, and in 1807 he married at Eatisbon
