utes by 55° C* It grows both with and without oxygen 5 it is 
therefore facultative as regards its relation to this gas.” Its ac¬ 
tion upon the tissues is quite similar to that of the tubercle ba¬ 
cillus already mentioned, except that it acts far more rapidly 
and the necrotic, areas caused by it are characterized by a con¬ 
siderable formation of pus. 
Before closing I wish to call your attention to a parasite no¬ 
ticed in a recent number of the Breeder's Gazette. The inquiry 
stated that the ho^s in a certain section of Kentucky were at 
that writing affected with “a parasitic disease causing swelling 
of the lower jaw, eruptions on nose, which enlarge until skin 
breaks, leaving the nose raw. After this the disease assumes 
the nature of a cancer. The nose rots away, the pig gets thin 
and weak and dies.”. The reply was as follows : “This trouble 
is caused by a parasite resembling that of mange and whenever 
it exists a poisonous matter seems to be produced.” As any 
parasite answering the above description is a total stranger to 
me I mention this here, hoping that any of you who have ever 
met him will hasten to introduce 11s. 
This touches briefly a part of the pathogenic micro-organ¬ 
isms. Many interesting forms are left unmentioned. 
Many questions relative to the subject which we would like 
to have answered, are still waiting for farther investigation, 
and there is still room in this field for careful experimentation 
and for earnest study and thought. 
DISCUSSION. 
Dr. Stewart: We certainly have had the pleasure of listen¬ 
ing.to an exceedingly interesting paper. To one who is not 
familiar with the problems presented they may seem somewhat 
difficult, but the author of them has made the understanding of 
them more easy. There were some points brought out in the pa¬ 
per which were somewhat new to me or at least somewhat differ¬ 
ent than I have been accustomed to think of them, and I would 
be very much pleased if the author would make some explana¬ 
tion before the discussion of this paper is closed. If I remember 
correctly, the author stated that a variety of the micrococci be¬ 
haved in the animal economy like anthrax bacilli ; that they 
multiplied in the blood stream and adhered to the vessel walls, 
producing thrombi or infarcts with haemorrhage into the tis¬ 
sues.. As. I understand it, the ordinary micrococci do not 
multiply in the blood stream, nor do they produce capillary 
haemorrhages. The author classed hog-cholera as a variety of 
septicaemia and this would seem a rather unusual classification.
