TEE HISTORY OF ICHTHYOLOGY.* 

 Science consists of human experience, 

 tested and placed in order. The science of 

 ichthyology contains our knowledge of 

 fishes, derived from varied experience of 

 man, tested by methods or instruments of 

 precision and arranged in orderly sequence. 

 This science, in common with every other, 

 is the work of many men, each in his own 

 field, and each contributing a series of facts, 

 a series of tests of the alleged facts of 

 others, or some improvement in the method 

 of arrangement. As in other branches of 

 science, this work has been done by sin- 

 cere, devoted men, impelled by a love for 

 this kind of labor, and having in view, as 

 'the only reward they asked, a grateful 

 remembrance of their work.' And in token 

 of this reward it is well sometimes, in grate- 

 ful spirit, to go over the names of those 

 vi^ho made even its slight degree of com- 

 pleteness possible. 



We may begin the history of ichthyology 

 with that of so many others of the sciences, 

 with the work of Aristotle (383-322 B.C.). 

 This wonderful observer recorded many 

 facts concerning the structure and habits 

 of the fishes of Greece, and in almost every 

 case his actual observation bears the 

 closest modern test. These observations
