An intermittant edematous swelling of the head and neck was present. The temperature of the dog when admitted was 102.2° F. and varied from 100.2° F. to 1040 F. during hospitalization. The appetite was retarded throughout the period of observation. All physical findings were negative except for the intermittant swelling of the head and upper cervical region which became more pronounced and further pTogressed to the lower cervical and pectoral regions. The animal preferred a prone position and walked but little when forced to exercise. The animal's condition was one of general decline until he expired on Dec. 3, 1944, following 21 days of hospitalization.
