IV ANNUAL OF SCIENTIFIC DISCOVERY. 



From the Prof, of Comparative Anatomy, Harvard University. 



I have examined the zoological portion of the Annual of Scientific 

 Discovery, which contains a faithful account of the progress recently 

 made in this department of natural science. It is a work of great 

 value in all its departments, containing, as it does, a record of the va- 

 rious discoveries made during the past year. 



J. WYMAN. 



From Doctor Gould, Boston. 



Having seen the Prospectus of the " Annual of Scientific Discov- 

 ery," and having also glanced at a considerable portion of the manu- 

 script, I am confident that a work on the plan proposed will be of the 

 highest value to the community ; and I am pleased that it has been 

 undertaken. The American mind is eminently inventive, and, of 

 course, specially interested in the progress of discovery. This work 

 will bring within a convenient compass the very information wanted. 

 My acquaintance with the editors and the facilities they enjoy gives 

 assurance that the work will be well digested, and will become increas- 

 ingly interesting and valuable from year to year.
