Robert M. Yerkes, assistant professor of compara- 

 tive psychology, Harvard University. 



The Animal Behavior Monograph Series 

 will be published in conneetioii with the Jour- 

 nal as a provision for papers which are too 

 lengthy, or, for other reasons, too costly to 

 be accepted by the Journal. The monographs 

 of this series will appear at irregular inter- 

 vals and will be grouped in volumes of ap- 

 proximately 450 pages. 



The Journal of Animal Behavior and The 

 Animal Behavior Monograph Series will be 

 published for the editorial board by Henry 

 Holt and Company, New Tork. Manuscripts 

 for the Journal may be sent to the managing 

 editor, Professor Eobert M. Terkes, Emerson 

 Hall, Cambridge, Massachusetts, or to any 

 other member of the editorial board. Manu- 

 scripts for the Monograph Series should be 

 sent to the editor. Professor John B. Watson, 

 Johns Hopkins University, Baltimore, Mary- 

 land, from whom information may be ob- 

 tained concerning terms of publication. 

 Books and other matter for review in the 

 Journal should be sent to the editor of re- 

 views, Professor Margaret F. Washburn, 

 Vassar College, Poughkeepsie, New York. 



The concluding (October) number of vol- 

 ume 11 of the Transactions of the American 

 Mathematical Society contains the following 

 papers : 



Virgil Snyder: "Conjugate line congruences

A SECOND EARLY NOTE ON THE TRANS- 

 MISSION OF TAWS BY FLIES 

 In Science for January Y, 1910, I com- 

 municated a note giving observations made 

 by Edward Bancroft in 1Y69 on the trans- 

 mission by flies of this malignant tropical 

 skin disease. Eecently in looking over Henry 

 Koster's " Travels in Brazil in the Years 

 from 1809 to 1815," published in Philadel- 

 phia in 181Y, I found the following more spe- 

 cific statement as to the means of transmis- 

 sion of this loathsome disease. In Vol. II.,
