570 DISEASE IN WILD MAMMALS AND BIRDS 
of the notes and sections. Actinomycosis is usually uni- 
lateral while leontiasis ossium is commonly bilateral; 
the tumors have not broken down nor spread into the 
neck. In one macerated jaw bone the osteoporosis and 
hypertrophic periosteitis were comparable to those of the 
bo\dne form but the masses were not so extensive as 
is common for domestic cattle. 
Treatment of this disease was attempted in the tapirs 
but not in the deer; the latter are too nervous to be 
handled repeatedly with safety to themselves. Follow- 
ing the usual method, potassium iodide was administered 
in saturated solution on bread, beginning at twenty grains 
thrice daily and rising in twoi cases to sixty grains thrice 
daily. It cannot be stated that any material improve- 
ment followed this heavy dosage although in one case 
the disease was very protracted — some six months, so 
that it may have modified the progress of the lesion. 
However, other things were done for the beast so that 
the effect of any one kind of treatment is difficult to 
evaluate. It was noted that iodide served to keep the 
stools quite loose and that its withdrawal was followed 
by constipation; upon resumption of the drug normal 
bowel movements appeared. Every soft spot was opened 
surgically to allow^ the pus to drain away. A vaccine of 
Act. bovis was prepared and injected under the hide be- 
ginning at 0.5 mg. and rising to 2.5 mg. in five doses after 
which the animal became so unruly that the injections had 
to be discontinued. On the whole we are not impressed 
with the probability of success in the treatment of actino- 
mycosis in tapirs. In the future we propose to try opera- 
tion and the use of Dakins solution or Dichloramin T. 
Streptothricosis or Nocardiosis or Kangaroos. 
A fatal disease of Australian marsupials character- 
ized by swellings and ulcerations about the lips, teeth, 
tongue and cervical tissues is knov/n apparently all over 
the world bv observers of these animals in collections.
