"Science consists of human experience, tested and 

 placed in order. The science of ichthyology represents 

 our knowledge of fishes, derived from varied experiences 

 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 persons, 

 each in his own field, and each contributing a series of 

 facts, or series of tests of the alleged facts of others, or 

 some improvement in the method of arrangement." 



Jordan; introductory remarks to the History of 

 Ichthyology, being chapter twenty-two of a Guide to the 

 Study of Fishes.
