ANNUAL OF SCIENTIFIC DISCOVERY. 



Ill 



RECOMMENDATIONS. 



From the Prof, of Zoology and Geology, Cambridge. 

 The publication of annual reports giving short abstracts of the im- 

 portant discoveries and improvements made in the different branches 

 of the useful arts, and embracing also an account of the general prog- 

 ress of Science, has proved so eminently useful, that wherever- cir- 

 cumstances have favored such publications, they have been found 

 equally beneficial to those engaged in scientific pursuits, and to the 

 community at large. Such reports have, for a considerable period, ap- 

 peared in many parts of Europe, under various titles, either upon spe- 

 cial branches of science, or covering its whole ground ; but no similar 

 work has, I believe, hitherto made its appearance in this country. 

 An undertaking like the Annual of Scientific Discovery, which is in- 

 tended to give, from year to year, an abstract of the progress of Sci- 

 ence and Art, cannot fail to be highly acceptable in this country, while 

 it will at the same time contribute to elevate the standard of American 

 activity and research abroad, where the proceedings of scientific men 

 on this side of the Atlantic are not generally so well known as they 

 ought to be. It therefore gives me great pleasure to say, that in my 

 opinion the editors of the present work, one of whom, as a member of 

 the Lawrence Scientific School, at Cambridge, has been under my 

 personal instruction, are fully qualified to execute the difficult task of 

 preparing such an abstract with credit, both to themselves and to the 

 country. Having examined in manuscript a considerable proportion 

 of the first volume, I can but highly recommend it. As it is designed 

 to meet a want extensively felt, I hope its reception will be such, that 

 the editors may be encouraged to continue it annually.

From the Prof, of Chemistry in the Lawrence Scientific School. 



I have examined, somewhat in detail, the manuscript of the Annual 

 of Scientific Discovery, and take great pleasure in bearing testimony to 

 the fidelity with which the work has been prepared. The editors, one 

 of whom has prosecuted experimental chemistry in my laboratory with 

 the highest success, are eminently qualified to undertake such a work. 



As a compendium of the new and useful truths contributed to the 

 stock of human knowledge during the past year, presented in a form 

 acceptable to the general reader, and at the same time so systematic 

 and complete, as to be of great service to the student of science, it 

 will be an honor to our country, and cannot fail to be appreciated and 

 liberally patronized by a discerning public. E. N. HORSFORD.
