incubation has been longer than any other recorded by Pasteur. 
It is difficult, perhaps, to explain the cause of it, but if this length 
of time is to remain unaltered in all cases, it naturally suggests 
the inquiry whether it would not be too late then for a patient to 
go to Europe from the United States, and would Pasteur’s treat¬ 
ment be likely to be successful. To oveicome this difficulty, the 
imperative necessity of being provided with the means of treat¬ 
ment at home becomes apparent. There has already been a Pasteur 
Institute organized in New York, which may secure to us the means 
of overcoming this difficulty. But there is something peculiar in 
the inaction of the National Government, which has thus far 
quite ignored the whole matter. The attention of Congress and of 
the Executive may easily be and very often is absorbed by matters 
of much less interest than the investigation of the work of Pas¬ 
teur in rabies, and, truly, in all the contagious diseases he has 
already studied. What great difference exists between the Ameri¬ 
can Government and the Governments of Europe, nearly every 
one of which has sent delegations or commission of investigators 
to his laboratory, Turkey, Italy, Germany and England having 
now in Paris medical commissions, sent there for the purpose of 
educating themselves in the science and experience of the inocula¬ 
tion treatment. Yet all that Americans seem likely to know on 
these vitally important subjects will probably be the fruit of 
private enterprize and philanthrophy. Not that this will not be 
as good and valuable as though the Government had paid for it, 
but a little official prestige in the matter would not have been 
at all improper or in the least out of order. Friends and members 
of the veterinary profession will be pleased to find the name of 
George Fleming on the list of the delegates who represent the 
English Governmennt in Paris. 
Pleural Sacs of the Horse Distinct and Separated.— 
Ever since the publication of the excellent work on “ Equine 
Anatomy,” by Bigot, in 1827, and reprinted since by almost all 
veterinary anatomists, and even in the works of St. Cyr, Lafosse 
and others, it has been held and taught by all clinical writers 
that the pleural sacs of the thorax of the horse are in communica¬ 
tion with each other, and that for that reason unilateral pleuritic
