MEMOIRJQF-SWAMMERDAM.^ 



EVERY one whose attention has heen turned, how- 

 ever cursorily, to the history of physiology or of 

 natural science, must he familiar with the name of 

 John Swammerdam. He revealed so many impor- 

 tant facts in the structure and functions of the lower 

 animals and investigated their anatomy with such 

 consummate skill, and scrupulous anxiety to discover 

 the truth, that he is continually referred to as one of 

 the highest authorities that can he cited. Indeed, 

 he may he said to have laid the foundation of all true 



* Our most diligent researches not having been successful 

 in procuring a portrait of Swammerdam, although we have 

 reason to believe that either a medal or an engraving exists, we 

 have been compelled to deviate slightly from our usual prac- 

 tice, and present the memoir without that appropriate accom- 

 paniment. To preserve the uniformity of our plan, and still 

 further to enrich our portrait gallery, we have prefixed a like- 

 ness of that distinguished entomologist, Baron de Geer, a sketch 

 of whose life has accordingly been added. The latter is neces- 

 sarily very brief, both on account of our space being exhausted, 

 and because materials are not to be found for a detailed bio* 

 graphy.
