MISCELLANEOUS INFECTIONS 601 
by small yellow or yellow-pink nodular elevations, appar- 
ently just beneath the surface, here and there upon the 
reddened, slimy buccal, lingual and pharyngeal mucosae. 
Crusts upon the skin of the neck also formed in this case. 
These cases are of interest not only because of their 
appearance without satisfactory explanation but because 
one improved very much after injections of human diph- 
theria antitoxin, this remedy being used because we were 
then unaware of the existence of an avian diphtheria anti- 
toxin. No claim can be made post hoc ergo propter hoc 
that the human antitoxin helped the attack — it may have 
been mild — but the experience is worth recording. Dosage 
was as follows : December 3, 3,000 units ; December 8, 
1,500 units ; December 21, 5,000 units ; December 27, 5,000 
units. Shortly after the inception of the treatment the bird 
was noticed to eat better and to be more lively ; this was 
followed by a reduction in the mucous strings in the mouth 
and the crusts upon the skin. This improvement con- 
tinued and the bird seemed Well in about two months but, 
after the lapse of three months more, a mucous naso- 
pharyngitis was again observed. Despite two injections 
of 5,000 units human diphtheria antitoxin the bird suc- 
cumbed five days after the beginning of this attack. 
Autopsy revealed much the same condition as was found 
in the first birds and from the lar\aix the Bac. avium was 
isolated. Another case suggestive of diphtheria was seen 
in a hornbill but antemortem observation being imprac- 
ticable and postmortem decomposition being advanced 
when autopsy was perfonned, the diagnosis could not 
be confirmed. 
An unusually well developed case of molluscum con- 
tagiosum was seen in the Wild Turkey {Meleagris gallo- 
pavo) recorded here by photograph and in the form of 
notes upon the histology made by Doctor Weidman. 
The bird's head was affected universally from beak 
to ears by horny nodules up to the size of a pea. They 
were so large and numerous around the eyes as to com-
