The occurrence of a large tumor (cylindromatous 
endothelioma) in the neck of a Coypu rat afforded an 
opportunity to attempt transplantation, with the hope of 
securing a new strain of tumor for experimental purposes. 
All of the conditions obtained favorable to a successful 
''take." The tumor was excised and Dr. White intro- 
duced a portion at once (within 10 minutes) under 
aseptic precautions under the skin of two of the offspring 
of the original tumor-bearing animal, i. e., the postulate 
as to blood relationship was ideally fulfilled. In spite of 
all these favoring conditions the transplants did not take; 
which is no more than occurs very frequently in the case 
of spontaneous white and gray mouse tumors. The 
original growth turned out to be a cylindromatous 
endothelioma of cervical salivary gland when examined 
microscopically. The patient recovered, its wound healed 
and it was returned to its enclosure for exhibition. The 
later history of the animal will probably never be known, 
since it disappeared at once and has not since been seen. 
Dr. Ellen P. Corson- White has been appointed to the 
Laboratory staff to take over some of the duties formerly 
performed by Dr. Fox. She has made some chemical 
studies in osteomalacia, and is about to begin some 
experimental cancer work with white rats; but none of 
the work on these subjects has advanced as yet to the 
point where she can report progress. 
The Pathological Society of Philadelphia met in this 
Laboratory on May 24th, 1917. The programme, furnished
