the electric pole of the track in such a manner that the continuity 
of the electric current through the body of the animal exists ; 
and, again, if, as it has been proved, horses placed in different 
conditions have been killed suddenly by the traumatism of the 
shock only, the death can only be attributed to a special phy¬ 
siological condition due to excess of work (very accelerated res¬ 
piration and circulation, abundant perspiration, etc., etc.). 
Finally, when such accidents occur in the street, if the ani¬ 
mal can be dragged off from the contact with the electric pole, 
there is great chances that his life can be saved, as the sequelae 
of even a very severe electrization are generally harmless. Of 
course, the dragging of the animal must be done with care to 
avoid danger.

FOURTH LOT, COW 9—INTRAVEINAL INOCULATION. 
The evening of the inoculation at 7 o’clock this cow was af¬ 
fected, short breathing, dejection, loss of appetite and elevation 
of temperature. Until May 22 hyperthermy had been inter¬ 
mittent, but from that date the temperature remained high with 
slight variation. 
The infection was very marked the 14th day, when she mani¬ 
fested very plain symptoms. The head is turned on the neck, 
the physiognomy anxious, the nostrils are dilated, the respiration 
is short, 60 a minute ; the respiratory sounds remain, a capricious 
appetite, a frequent short failing cough. The following days 
the same symptoms became more pronounced, the prostration is 
very great and the animal is almost constantly lying down. 
May 30 the animal No. 9 fell in a veritable marasmus and 
physiological helplessness; she has lost considerable flesh, her
