MICROSCOPICAL FORMS FOUND NEAR SALEM, MASS., BY T. COLE, ESQ, 



For the following interesting list of microscopical forms found near Salem, Mass., 

 I am indebted to Thomas Cole, Esq., of that place, who has for several years 

 examined these forms with great zeal, and who, I believe, was the first person 

 to make a systematic study of the American soft skinned Infusoria. This list 

 will be useful for the purpose of comparing the forms of the Northern and 

 Southern States. The names employed by Mr. Cole are those used by Ehren- 

 berg, in his large work Die Infusionsthierchen, with the descriptions and figures 

 of which each form was compared.
