ANSWERS TO OOERESPONDENTS. 



X. Y. Z. — The second niimber of the Journal of 

 Morphology which forms the first volume, will be 

 issued about January 1. Price for the volume $6.00. 

 Single numbers $3.50 each. This Journal of Animal 

 Morphology is devoted principally to Embryological, 

 Anatomical and Histological subjects. Only original 

 articles, which deal thoroughly with the subject in 

 hand, are aduiitied to its pages. Thus what is newest 

 and best in Zoological Literature is matle early avail- 

 able to the Zoologist instead of being irretrievably 

 scattered and inaccessible among the bulletins and 

 memoirs of the various scientihc societies.
