 Hall, Cambridge, Mass.) Separate numbers are for sale at the 

 prices listed above. The management of the Journal of Animal 

 Behavior wishes to announce that the Behavior Monographs have 

 been well received and that, in spite of the low subscription 

 price at which they are issued, they promise to reimburse their 

 authors within a reasonable time. 



Attention is called especially to the fact that the Monographs 

 are published irregularly, and not necessarily at the rate of a 

 volume per year.
