514 EDEMA FOLLOWING NEPHRECTOMY 



Addendum. — After this article was in press, the work of Miss Ruth B. How- 

 land* came to my attention. The results obtained by Miss Rowland on the 

 embryos of Amblystoma are essentially similar to those described above by me 

 for the frog. It is an agreeable duty for me to ackowledge, however, the full 

 priority of Miss Rowland's results.
