"VOX.. III.— I=.A.RT III_ 



The third and concluding part of the present volume is now 

 in course of publication, and will be exclusively devoted, as a 

 fitting tribute, to the memory of the late President, Joseph Dun- 

 can Putnam, to whose earnest zeal and untiring labors all the 

 previous publications of the Academy are mainly due. It will 

 contain his unfinished work on Solpugid(E^ which has been 

 arranged for publication by Prof. Herbert Osborn, of Ames 

 College. This work will be illustrated by seven plates from his 

 own drawings, the engraving of which will be superintended by 

 Dr. H. A. Hagen, of Cambridge. It will contain a complete 

 bibliography of the Solpugidce^ compiled by him, and now pre- 

 pa'ed for the press by Miss Julia Sanders. This part will also 

 contain a steel-plate engraving of Mr. Putnam, a,^«i»memorial 

 address, by Prof. W. H. Pratt ; a biographical sketch of his life 

 and work, by Dr. C. C. Parry, and such memorial notices as 

 may be appropriate to conclude a work with which his life and 

 memory are indissolubly connected.
