 its careful elaboration we must still wait. Various faunal 

 papers — far too numerous for enumeration in the present 

 connection — have also been published. New workers are 

 also every year entering the field; so that the outlook for 

 the further progress of North American mammalogy is full 

 of encouragement.

 American Mammals have been acquired by the American Museum of Natural 

 History in New York City.
