virulence are negative and positive. Among tlie negative 

 facts, liowever, those must be distinguished which have refer- 

 ence to the milk derived from animals only bitten by mad 

 dogs, and those really affected with the disease." 



" Andray reports that peasants have used, for more than a 

 month, the milk of a cow which was wounded by a mad dog, 

 without experiencing any inconvenience.* 



" An infant fed on the milk of a goat until the day the 

 animal became mad, remained in perfect health. And, what 

 is more striking, another child drank the warm milk drawn 

 from a rabid cow, and no ill effects followed. The veteri-

 which several persons had drunk the milk of a rabid cow 

 every day from the commencement until the fatal termination 

 of the disease. Though some of them were plunged into the 

 greatest terror, none were affected with the disease. 



" The experiments made by Baumgarten and Valentin 

 concord with the observations made by Gelle ; they are also 

 confirmed by the researches instituted by Baudot, who, a great 

 number of times, noted that neither the milk nor butter ob- 

 tained from rabid cows produced unpleasant effects on whole 

 families who had consumed these articles of food.f

 wounded by a rabid dog was soon after delivered of twin 

 lambs, which of course it suckled. Twenty-one days after 

 the infliction of the bite the ewe became rabid, and died, but 

 the lambs did not manifest any signs of the disease. 



" The only positive statements I can meet with as to the
