The foregoing remarks have been called forth, by a 

 desire to see a more perfect Catalogue of the Fishes of 

 Massachusetts. While the other departments of Natural 

 Science among us, are yearly enlisting the aid of zealous 

 and devoted students, who capture, with enthusiasm, 

 the minutest insect— and carefully separate from collected 

 sand, the microscopic shell— and arrange both, with sci- 

 entific knowledge. Ichthyology, if not despised, is utterly 

 neglected. It is time an efert should be made by this 

 Society, to become better acquainted with the inhabitants 

 of our waters ; and while the slight means possessed by 

 the writer, shall be employed to the best of his ability, he 

 trusts that others, possessing superior advantages for their 

 mvestigation, will as freely offer the fruits of their labors.
