22 Biographical Memoir of the late Henry Kuhh 



Van Hasselt, and their papers on this subject are consequently 

 common. These papers, indeed, chiefly treated of the whole 

 first four classes of vertebrate animals ; but we may mention 

 one in particular as worthy of praise, which contains a disputa- 

 tion regarding the hearts of various animals. In them, as well 

 as in the other writings of Kiihl, many new facts are detailed. 

 On their voyage to Java, although they paid most attention to 

 the dissection of invertebrate animals, yet, by their industry, 

 they also extended the anatomy of the vertebrate ones. 



In regard to the vegetable kingdom, they paid particular at- ' 

 tention to the laws of the distribution of plants over the surface 

 of the earth, in respect to which they instituted many and very 

 diligent investigations in the Island of Madeira, at the Cape of 

 Good Hope, and in Java. "^ 



In mineralogy and geology we are indebted to them for an 

 account of the geological structure of Madeira, for a better view 

 of the South Cape of Africa, as weU as remarks upon the Co- 

 coa Islands, and, lastly, for various communications illustrative 

 of the colony of Buitenzorg in Java.

 ad alteram progrediatur, atque sic continuam quasi catenam efficiat, ex 

 variis quidem annulis, intime tamen junctis compositam, hsec catena, in
