MEMOIR OF SWAMMERDAM * 
Every one whose attention has been 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 be 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 Blightly 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.
