T. Y. Chambers, Covington, Ky. ; Dr. E. Palmer, Boston. A 

 detailed catalogue of this collection has been commenced. 



The alcoholic collection has been carefully examined and studied 

 through all orders except for Orthoptera and Hemiptera. The 

 American Spiders are in the hands of Count von Keyserling, 

 Glogan, Silesia ; the Scorpions have been sent to Mr. E. Simon, 

 Paris, France, and all Myriapods to Dr. Fr. Meinert, Copenhagen, 

 Denmark, for determination and scientific study. Therefore the 

 whole alcoholic collection will be in a condition to be arranged after 

 the return of those parts. The whole biological collection of the 

 Ephemerina and part of the systematical collection have been in 

 the hands of Rev. E. A. Eaton, Croydon, England, to be used 

 in his monograph of this family. The ^geridse have been in the 

 liands of Mr. H. Edwards for his monograph.
