IB INFECTIVE AND CONTAGIOUS DISEASES; 
There is evidently a great future in store for our profession 
in America. 
We have now completed our work, and hope we have 
collected material interesting to the English practitioner. 
If any American reader notes errors, let him be assured 
that we shall be anxious to correct our statements when 
proved to be in the wrong. 
ABSTRACT OF LECTURES, BY DR. W. S. GREEN¬ 
FIELD, Professor Superintendent of the Brown 
Institution, ON “ RECENT INVESTIGATIONS 
IN THE PATHOLOGY OF INFECTIVE AND 
CONTAGIOUS DISEASES.” 
SPECIALLY REPORTED. 
On Wednesday, 17th December, at 5.30, Dr. Greenfield 
commenced his course of lectures in connection with the 
Brown Institution at the University of London, in the Theatre. 
The' audience was large, including several well-known medical 
and veterinary practitioners and professors. The proceedings 
were opened by Dr. Quain, who, as chairman of the Committee 
of the Brown Institution, introduced the lecturer, taking 
advantage of the opportunity to allude to the valuable services 
rendered to science by Dr. Burdon-Sanderson, as based on the 
experiments and observations made by him at the Institu¬ 
tion, and also, by a few judicious remarks, to condemn the 
proceedings of those individuals who fail to see that the small 
amount of injury inflicted on the few in such investigations as 
are pursued at the Brown Institution must be productive of a 
very large amount of benefit to man and to the many lower 
animals. The lecturer was received with applause. 
He commenced his lecture by some remarks on the position 
which the “ relation of diseases of animals to man ” occupies in the 
minds of medical men, and expressed his opinion that it is not 
adequately appreciated. He gave those illustrations of the relations 
between diseases of animals and those of man which are most 
familiar to us, and said that the only instances of attempt to 
inoculate animals with human morbid products with which he is 
familiar are vaccination for distemper in dogs, not in his opinion 
a very hopeful operation. He alluded to Drs. Klein, Sander¬ 
son, and Simon, as workers in this matter, and stated that for 
assistance in his researches he is indebted to Mr. Banham,
