The dried powder is again triturated and diluted in water 1 
per cent.; of this one cubic centimeter is used for each inocula¬ 
tion. The authors now inoculate cattle at about two hands dis¬ 
tance from the extremity of the tail. At the present time the 
cattle inoculated 17 months ago retain the immunity acquired by 
the inoculation. 
In the last chapter, this careful and beautiful study of the 
laboratory is supported by the practical statistics of the inocula¬ 
tion of nearly a thousand cattle and sheep on farms in the south 
of France and in Algeria. These inoculations commenced in 
1880, and continued through 1881-82. On infected farms and 
mountainous pastures not one of the inoculated animals died of 
blackleg, while the uninoculated belonging to the same proprie¬ 
tors or their neighbors and placed in the same surroundings, paid 
their regular tribute to this scourge of agriculture.
