Mulford Biological Exploration of the Amazon Basin 

 News Bulletin No. 9. 



The following letter from Dr. \Y. deC. Ravenel, Administrative 

 Assistant to the Secretary in charge of the U. S. National Museum, 

 was recently received by Mr. Milton Campbell, President of the H. K. 

 Mulford Company : 



"I now take pleasure in advising you that a large amount of addi- 

 tional material collected by Dr. William M. Mann, while a member of 

 your Exploration Expedition, has been turned over to the collections, 

 comprising insects, mammals, shells, crustaceans and textiles. All of 

 the material is recorded as a gift in the name of the Mulford Biological 

 Exploration of the Amazon Basin, and 1 would repeat my assurances 

 of our appreciation of the generous interest which has been manifested 

 in the national collections." 



In reply to the communications from Dr. Ravenel, Mr. Campbell, 

 President of the H. K. Mulford Company, thanked him for the gen- 

 erous expressions of appreciation and said, "It is a pleasure indeed to 

 present these collections to the Smithsonian Institution in view of the 

 splendid work the Institution is doing and its importance to the 

 country." R. H. HUTCHISON, Secretary. Philadelphia, Pa. 



The Exchange of Scientific Literature with Russia. 



Apropos of the note on this subject published in the NEWS for June 

 of this year, page 186, we reprint the following from Science for July 

 14, 1922, page 45 : 



"The officers of the Russian Entomo-Phytopathological Congress sent 

 a request some months ago to American scientific societies and investi- 

 gators to send to Rus.sia literature on entomological and phytopathologi- 

 cal matters. 



"In connection with this request the Russians promised to send Russian 

 scientific literature in exchange. Certain difficulties, however, have 

 been found to exist, principal among which is a regulation by the Soviet 

 ', \eniment, made about two months ai-o, which prohibits the sending 

 out of literature from Russia without a special permit. This permit 

 seems very difficult to get. The Russian scientific men, therefore, who 

 have received American scientific literature in response to their request, 

 feel much embarrassed by their inability to respond by sending Russian 

 literature here, and I have promised to make known, in this way, the 

 facts which have prevented their promised sending of Russian literature 

 to those Americans who have kindly sent scientific papers to them.- 

 YKRNON KELLOCL." 



In this connection we may caM attention also to the arrangements 

 which have been made for sending scientific works to Russia, described 

 at lenet'n in Science for June 22. } t >22. pa^cs nn7-o68.
