with morphia hydrochloric 2.0, and ag. amydulae. amar. 200.0 ; 
ten grams of which solution were injected into the larynx of 
each patient every morning and evening. All my patients 
similarly affected were treated by this method as regularly 
as possible, considering they were not in such close proximity 
as Jelkman’s, which were all in one stable and received im¬ 
mediate attention. And I believe I have acquired evidence 
enough to justify my saying that throat diseases are more 
readily controlled by this than any other way. A similar 
and equally valuable modus operandi as the preceding is the 
tracheal injection. Prof. Dieckerhoff reports excellent re¬ 
sults with injections of Lugol’s solution into the trachea in 
morbus maculosus (blut-flecken-krankheit). 
“ Though not new, I have not noticed any,accounts either 
for or against this procedure lately. It is a much safer 
method than drenching, which, in cases of difficult degluti¬ 
tion, as, for instance, in parturient apoplexy which started 
the peristalsis, attended with moaning, indicating pain, but 
did not affect a cure. 
“ Now that the discoveries of micro-organisms, tuberculin, 
mallein, etc., have revolutionized the veterinary medical world, 
I shall not be surprised that some day one or the other of 
our great scientists may find himself the discoverer of specific 
antidotes against bacilli and their mischievous results.”

guinea-pigs with blood taken aseptically from the carotid or 
the femoral arteries of vaccinated animals, and tested against 
swine plague or against infectious pneumoenteritis. The blood, 
collected in a sterilized tube, was placed for several days in a
