SUPPURATIVE CELLULipS DUE TO STREPTOCOCCUS INFECTION. 171 
there had been a profuse discharge. At this time pus could not be ob¬ 
tained. Several small pieces of the infiltrated tissue were secured.* 
From some of these agar tubes were inoculated at the time and the 
others were placed in sterile tubes and brought to the laboratory for fur¬ 
ther examination. 
Case No. 2. This was in a cow, about six years old, in the same dairy. 
The left fore leg was just beginning to swell. There was evidence of 
pain and the skin from the hoof to the knee was sensitive to the touch. 
The temperature was normal, but there was indifference to food. This 
case was treated locally by Dr. Taw, with recovery without suppuration. 
Case No. 3. (Cases 3 to 5 were in the second herd.) This was in a 
cow, seven years old. The right hind leg was affected. The disease had 
already run about three weeks and for several days the animal had been 
under the care of a veterinarian. The cellulitis had extended up the 
leg to and above the hock joint and down to and over the coronary 
cushion. The hoof covering the heel had cracked and part of it had been 
removed. There was a large subcutaneous abscess above the heel,which 
was discharging through an opening or crack in the hoof near the mid¬ 
dle of the bottom of the foot. It was stated that at first the pus was 
thick and of a cream color, but at this time it was thin and of a dirty 
brown tint. By means of pressure a considerable quantity of it was 
forced out, from which tubes of agar were inoculated and a few cubic 
centimeters placed in a sterile tube and brought to the laboratory. 
Case No. 4. This was in a two-year-old heifer. The left hind foot 
was attacked. The leg was slightly swollen. There was distinct fluc¬ 
tuation over an area about 3 cm. in diameter, on the front of the foot and 
just above the hoof. The animal seemed to be well otherwise. Tem¬ 
perature normal and appetite good. The hair was clipped, the foot care¬ 
fully washed and disinfected and the abscess opened. It contained about 
5 c.c. of a thick creamy looking pus. Several tubes of agar were in¬ 
oculated from this and the balance placed in sterile tubes for further 
examination. 
Case No. 5. This was in a two-year-old heifer. The left hind foot 
had been affected,but at this time it had discharged, the swelling had 
subsided, and the abscess was practically healed. 
The disease in Cases Nos. 3 and 4 seemed to resemble Pan¬ 
aritium,* the essential difference being in the extent of the in¬ 
flammatory process. Until the specific cause of that affection 
is more definitely determined, and the extent of the lesions in-
