724 THE DANGER OF MILK FROM PHTHISICAL COWS. 
The medullary artery of the femur is sometimes given off 
through the foramen at the anterior part of the bone instead of 
at the internal surface of the bone. The artery of the humerus 
is similarly variable. The circumflex of the toe is variously 
formed in different cases. 
Thus from these examples we see the arteries are the most fre¬ 
quent subject of variation. The veins also are not regular. 
These differences are as numerous and as marked as those in 
man. 
Our observations point to important affinities, and, we have 
reason to believe, may direct attention to conclusions by no 
means as yet generally received. So we are in hopes that we 
have not over-estimated the importance of our subject. Investi¬ 
gation of varietal modification of domesticated animals should 
teach us the general laws and methods of modification, and thus 
bear fruit in advancement of the science of anthropology, in 
promoting the scientific management of our animal servants, 
and in rendering our knowledge more exact with regard to those 
forms which inhabited the earth in by-gone ages. 
THE DANGER OF MILK FROM PHTHISICAL COWS. 
Dr. V allin, in the Revue d } Hygiene, briefly referring to 
recent contributions on this subject, including the writings 
of Fleming, and especially Dr. Creighton’s recent paper in 
The Lancet, on an infective variety of tuberculosis in man 
identical with bovine tuberculosis, urges the attention of 
scientific bodies to the subject. These bodies, he says, have 
at different times instituted commissions for the study of cow- 
pox, rabies, glanders, &c.; should they not institute a com¬ 
mission for an investigation such as this? He especially 
urges the question upon the attention of the Institute or the 
Academy of Medicine. Here is a subject which specially 
concerns the medical department of the Local Government 
Board, and which we should be glad to see included in the 
scientific medical research carried on by that department in 
continuation of Dr. Burdon Sanderson’s investigations, made 
for the department, on the inoculation and development of 
tuberculosis. Meanwhile, asks Dr. Vallin, pending the ex¬ 
perimental determination of the question at issue, is it not a 
matter of common prudence, in giving milk of which the 
source is doubtful to infants and invalids, that it should first 
be thoroughly boiled? Unless we are mistaken, it has been 
alleged that boiling does not offer a sufficient protection?—
