'12 Biographical Memoir of the late Henry Kiihl. 



spent almost the whole da} there, in examining all the genera 

 of invertebrate animals which they found. At the same time, 

 they read in the evenings at home the works of Cuvier and Sa- 

 vigny, on the anatomy of these animals, and received various ob- 

 jects for examination from the former ; and, besides, Kiihl oc- 

 cupied those hours in which Van Hasselt and Cremersius at- 

 tended the medical lectures and hospital, chiefly in collecting 

 materials for his work on amphibia, birds, and other animals. 



The distinguished Cuvier also, had a literary party on the 

 Saturday evenings, to which all the learned men residing in 

 Paris were usually invited, and Kiihl and Van Hasselt were 

 constantly invited to attend. These were also allowed free ac- 

 cess to Cuvier's library, and were permitted to work in the same 

 apartment with him ; while orders were at the same time given 

 to the different keepers of the museum, to open all the cases to 

 them when required. 



But, without doubt, among so many illustrious men, he was 

 most disposed to pay the tribute of admiration and esteem to the 

 celebrated Humboldt, a man equally noted for his benevolence, 

 learning and prudence. Humboldt procured for Kiihl and his 

 friend free access to the Royal Institute, by which they were al- 

 lowed to attend the sittings and make use of the library ; be- 

 sides, he very kindly offered Kiihl the use of his own libraty, 

 and did not think him unworthy of being admitted among the 

 number of his particular friends. During his residence at Paris, 

 Kiihl completed his monograph on the genus Psittacus, which 

 was printed in the tenth volume of the Transactions of the Leo- 

 poldine Society. 



Leaving Paris on the 26th February 1820, he returned straight 

 to Hanau, where he laboured with indefatigable diligence in cor- 

 recting his manuscripts, so as to be able, soon after, to send to the 

 press, his first volume of " Additamenta ad Zoologiam et Ana- 

 tomiam Comparatami" After reducing all these to order, he 

 took leave of his father and family, and proceeded to Amster- 

 dam, in order to make preparations for his journey ; this done, 

 he went to Groningen for the last time, and after staying there 

 one day, bade adieu to his friends. On the 10th July 1820, 

 the ship in which he embarked, commanded by Breukcmeyer, 

 sailed from the Texel.
