ble. With this end in view the committee defined the word 
contagious ” at the outset of the report, and any discussion 
subsequent portions must necessarily be based upon that 
afinition. 
If Dr. Schwartzkopff has .effectually overthrown the 
ignition of contagion his criticisms of subsequent por- 
ons of the report 4 are wholly irrelevant, as the report 
uds in so far as the word contagious is involved when 
i at definition is destroyed, while if the definition re- 
lains the criticism must be based thereon. There is 
lanifestly nothing to be gained by Dr. Schwartzkopff 
: cusing the committee of misstating the views of numerous 
;ithors on the subject of actinomycosis* when the sole 
round for such accusation rests upon the different concep- 
ons held by the disputing parties as to the meaning of a 
ord, the force and meaning of which in the report had al- 
:ady been clearly stated. The real foundation almost 
roughout Dr. Schwartzkopff’s criticisms rests upon this 
libble over the meaning of a word. 
Dr. Schwartzkopff criticises the committee sharply for 
including that inoculation constituted a crucial test of 
mtagiousness, and asserts that pleuro-pneumonia of cattle 
has never been transmitted to any experimental animal.” 
he point seems, however, to be in controversy, and Arloingf 
ad Law;j: seem to hold opposite views to those set forth 
aove. 
Moreover, Dr. Schwartzkopff will doubtless admit that in¬ 
sulation produces a degree of immunity against this disease, 
ad in the present state of our knowledge this immunity can 
j; referred to but two sources—the growth within the body of 
‘ e inoculated animal of the pathogenic germ, or to the in- 
oduction into the healthy animal of toxic products resulting 
orn bacterial growth or presence. Admit the former and 
e immunized animal had pleuro-pneumonia; admit the latter 
id it was not inoculated with the disease-producing germ.
