262 THE POPULAR SCIENCE MONTHLY. 



took sucli shape that the Institute thought it advisable to in- 

 crease Its scientific force, and so in 18G6 it called to Salem four of 

 the students mentioned in the opening paragraph — Packard, Put- 

 nam, Morse, and Hyatt — as curators of the Institute collections. 

 These plans, however, took a different turn from that expected 

 by some, and the result was an independent institution, the Pea- 

 body Academy of Science, with an endowment of $140,000. The 

 Institute turned over its collections to the new corporation, and 

 with them went the four curators. They retained their connec- 

 tions with the Academy for varying lengths of time. Prof. Hyatt 

 was the first to leave, as he was oft'ered the position of custodian 

 of the Boston Society of Natural History. Prof. Morse left next, 

 and went to Bowdoin College as Professor of Zoology. Prof. 

 Putnam, in 1876, was appointed Curator of the Peabody Museum 

 of Archa3ology and Ethnology at Cambridge, another institution 

 which owed its existence to the liberality of Mr. Peabody. Dr. 

 Packard retained his connection with the Peabody Academy of 

 Science until 1878, when he resigned to accept the professorship 

 of Zoology and Geology in Brown University, a position which 

 he holds to the present time. 



These twelve years at Salem were prolific. in work, only a 

 small fraction of which can be noticed. Possibly the most im- 

 portant service done American science was the foundation of the 

 " American Naturalist," a popular magazine of natural history, 

 by Messrs. Packard, Morse, Hyatt, and Putnam, in 18G7. With 

 this journal Dr. Packard was connected, a part of the time as 

 sole editor, for twenty years, only severing his connection with 

 it in the beginning of the year 1887. It is difficult to overesti- 

 mate the value of Dr. Packard's editorial labors, and it is cer- 

 tainly safe to say that if we consider this point alone no one has 

 done more to shape American zoological science than he. Dr. 

 Packard, however, did other work. He had continually several 

 irons in the fire. Entomology was his chosen field, and, perceiv- 

 ing the lack of any manual for students in this department of 

 science, he published in 1869 the first edition of his well-known 

 " Guide to the Study of Insects," a volume which to this day is 

 without a rival. It may be said, parenthetically, that Dr. Pack- 

 ard is now engaged in completely rewriting this work so that it 

 may adequately represent the entomological science of the pres- 

 ent time. The same years also witnessed the publication of vari- 

 ous systematic and embryological papers, the principal one of 

 which was an account of the development of that ancient form, 

 the horseshoe crab. 



The old spirit of exploration was not extinct. Scarcely a year 

 passed without a trip to some point near or remote, the features 

 of which he wished to study. In the winter of 1869-70 he vis-
