after operation; dressings consisted of cold water bandages, iodo¬ 
form freely, and injections every two hours in drainage hole of 
hydrarg. per chi., one part in 1,000 of water; her diet consisted 
of green corn, apples and boiled grain liberally, and the stable 
surroundings kept unusually clean. She exhibited a great degree 
of intelligence on several occasions; in lying down she would 
forget and drop to the left side, but when she got ready to rise 
she would roll over on side of remaining member and rise without 
difficulty; her temperature never rose above 101°; pulse after 
operation 82°, but day following had dropped to fi4° and con¬ 
tinued to fall to 42°, at which it has remained. The mastoido- 
humeralis muscle has developed greatly , also all muscles of right 
extremity. 
In conclusion, I would say that I am of the opinion that many 
a valuable stock animal can be saved by amputation when the 
fracture will not justify treatment by usual methods, and that 
the wholesale slaughter of animals with broken limbs is utterly 
uncalled for when breed is valuable for stock purposes ; with 
posterior extremity there may be a difference with horses, but in 
cattle I have amputated a hind leg with the best of satisfaction 
on two occasions.

SIMILARITY OF SPONTANEOUS AND EXPERIMENTAL TETANUS. 
By using the dust of hay, Mr. Rietsch has confirmed the ex¬ 
periments of Nieolaier, Beumer and others, upon experimental 
lock-jaw, and has developed in a donkey the typical tetanus of 
equines, the dust being inserted under the skin of four cobayes, 
which after four or five days died of tetanus. A little pus, taken 
from these at the point of inoculation, was then used to inoculate 
two other guinea pigs, both of which died of tetanus thirty hours 
after. A very small quantity of pus taken from the last two 
was then used in the inoculation of two others, of which only one 
presented tetanic symptoms, but recovered. With the pus of 
one of the last dead guinea pigs cultures were made with gela-
