NATIONAL AND INTERNATIONAL MEAT INSPECTION. 129 
In stating that the proposed classification did not rest on 
facts and was therefore not scientific, Dr. Schwartzkopff 
denies the truth of fonr distinct propositions, which we had 
been led to believe were universally admitted by scientific 
veterinarians. They are : 
ist: Meat infested by certain living animal parasites when 
eaten by man is dangerous to health or life through the de¬ 
velopment or migrations, or both, of the parasitic organism. 
2nd : There exist diseases of animals, not transmissible to 
man, which can only injure the consumer of the carcass 
through the presence of chemical products, either the result 
of special micro-organisms or of tissue metamorphosis. 
3rd : There are many diseases transmissible directly from 
animal to man and the flesh of which contains a second ele¬ 
ment of danger to the consumer in the presence of ptomaines 
or other toxic products. 
4th: There exist bacteriological diseases of animals iden¬ 
tical with certain diseases of man, which in individual cases 
may affect the animal in so mild a form as to be dangerous to 
man only from the presence in the flesh consumed of living 
micro-organisms capable of transplantation. 
If these propositions are facts, a classification of diseased 
meats upon these is scientific, but if Dr. Schwartzkopff can 
show that these are errors, then the proposed classification 
:an never ensue. 
Supplementary to his charge that the proposed classifica¬ 
tion is unscientific, he misconceives the force of the worcl“may” 
is used in a piecemeal quotation from the report, and gives 
t a meaning not at all intended, and which we believe cannot 
3e substantiated by a strict English construction of the 
sentences. 
In attempting to justify his classification in the paper 
presented in 1890,* he presents as his only arguments the 
statement that it is the method generally employed in Ger¬ 
many, “ and has grown up from established facts and in con- 
ormity with practical principles.” He fails to note that the 
environments in Germany are quite different from those of
