As a Special Report we wish to add the following notes on 
Bird Diphtheria. 
During the year upon which this report is made, we have 
had two autopsies upon Cassowaries with Bird Diphtheria 
due to Bacillis columbarum and one case has been observed 
during life and apparently cured. We wish to put these cases 
on record not because of anything unusual of bacteriological 
or pathological interest, but because the last case mentioned 
was treated with human diphtheria antitoxin and recovered. 
The fatal cases showed large pseudo-membraneous collections 
on the mucous membrane of the naso-pharynx and beneath 
the tongue. The nares were occluded with similar material. 
The oesophagus and proventricle were diffusely reddened, 
and the mucosa3 had several small plaques of the exudate. 
Before death there was much discharge from the bill and a 
collection of dried exudate on the skin of the neck as far down 
^s the wattles. 
In the bird which passed through the attack a similar 
condition existed; there wer.e, however, no pseudo-mem- 
branes upon the mucosse as far as could be detected. 
This mucosa was reddened, slimy and slightly swollen. Here 
and there small yellow or yellow pink nodular elevations 
were seen under the surface of the mucosa membrane cover- 
ing the superior maxilla. Upon the skin of the neck a heavy 
crust formed from the discharge leaking out of the corners 
of the mouth. Long strings of mucus were seen when the 
bird opened its beak. At the suggestion of Mr. Carson the 
bird was given diphtheria antitoxin as follows: — 
December 3d, 3000 units; 
December 8th, 1500 units; 
December 17th, 5000 units; 
December 21st, 5000 units. 
Shortly after the beginning of this treatment the bird was 
more lively and ate better than it had for some time previous.
