[Vol. V., No. 120. 



ments of age, some time before his death ; but 

 his career is a long record of discoveries. He 

 was born at Wiirzburg, Feb. 16, 1804. His 

 elder brother, Eduard Kaspar Jakob, was a 

 prominent obstetrician, holding a professorship 

 at Gottingen at the time of his death. His 

 still older cousin, Philip Franz (not a brother, 

 as sometimes 

 stated), became 

 distinguished 

 by his very 

 successful sci- 

 entific jour- 

 neys in Japan 

 and the Indi- 

 an Archipela- 

 go. Carl The- 

 odor, like 

 Helmholz, and 

 many another 

 of the older 

 German men 

 of science, was 

 educated as a 

 physician, and 

 began life with 

 the practice of 

 his profession, 

 at first in a gov- 

 ernmental post 

 as a ' kreis- 

 physikus ' in 

 Heilsberg for 

 a year, next 

 as director of 

 the lying-in 

 hospital at 

 Dantzig. In 



1840 he definitely entered upon a university 

 career as professor of plrysiology at Erlangen ; 

 and, after several changes, he went to Munich 

 in 1853, and there remained until his death, 

 on the 7th of last April. 



His original work has been almost entirely 

 in the field of zoology, more especially in the 

 domain of comparative anatomy. His manual 

 of this last-mentioned science is a great 

 masterpiece, a model of truthful and critical 



compilation, supported by numerous original 

 observations. In this work an immense array 

 of facts are properly co-ordinated, and the whole 

 concisely presented. It is not too much to 

 say of this publication, that it has never been 

 surpassed as an adequate exposition of the 

 contemporary knowledge of comparative anat- 

 omy. Sie- 

 bold's own in- 

 , ~« v vestigations 



have been 

 very numer- 

 ous. His re- 

 searches on 

 the develop- 

 ment of the in- 

 testinal worms, 

 and also those 

 on parthenoge- 

 nesis, opened 

 new fields of 

 thought, and 

 the first-men- 

 tioned were of 

 great practical 

 utility to man- 

 kind. His 

 monograph on 

 the fresh- water 

 fishes of Eu- 

 rope is the 

 standard au- 

 thority on the 

 subject. To- 

 gether with 

 Kolliker, he 

 founded the 

 famous Zeit- 

 schrift fur wissenschaftlicJie zoologie, a journal 

 of the very highest character. The museum 

 at Munich, of which he had charge, is a beau- 

 tiful monument to his scientific and judicious 

 administration. Such, in brief, are the long- 

 continued and successful labors of one of the 

 most esteemed veterans of German science, of 

 one whose work and influence have contributed 

 much to give Germany of to-day the intellec- 

 tual leadership of mankind.
