sphere, which I have not been able to do, before coming to a conclu- 

 sion on this point. 



" That the virulent matter of glanders and acute farcy, which com- 

 pletely lose their contagious properties in the digestive organs of the 

 doo% the pif, and the fowl, retain them, although much diminished in

energy m those ot the horse. 



" That the virulent matter of the blood of the spleen, which the 

 dog, the pig, and the fowl may eat without inconvenience, often give 

 rise to carbuncular symptoms when it is swallowed by the herbivora, 

 such as the sheep, the goat, and the horse. 



" That this immunity, as regards contagion, which the carnivora and 

 omnivora fed with virulent matters enjoy, whilst the latter may produce 

 all their effects when they are swallowed by the herbivora, might be 

 owing to the virus being evidently from their origin, principles of 

 animal nature, would undergo, in organs destined for digesting ani- 

 mal food, modifications which by altering them profoundly, would 

 make them loose their deleterious properties, which, from their organ- 

 ization, are capable of digesting only vegetable aliments. 



" That whatever their explanation may be, it is proved, indeed, that 

 pigs and fowls, do not undergo, either in their health or in the quality 

 of the products which they furnish for the consumption of man, any 

 alteration in consequence of having been fed with matter from ani- 

 mals which have died of glanders or farcy, carbuncle or madness, and 

 that man may eat without danger the flesh and products of these 

 animals thus nourished." 



" That the baking and roasting of meats, and the boiling of liquids 

 arising from animals affected with contagious diseases have the effect 

 of annihilating the virulent properties of these meats and liquors to 

 such an extent, that not only may the glandered matter be swallowed 

 with impunity by the horse, the sheep, and the goat, and the remains 

 of fowls which have died of epizootia by fowls, but also that all these 

 matters which are so active, whose contagious power is so energetic, 

 and so certain when they are inoculated in the fresh state, remain 

 completely inert on every animal, even after their inoculation, when 

 they have been cooked. 



" The practical consequence of the facts explained in this memoir 

 is therefore : 



" That there exists no sanitary reason why pigs and fowls should 

 not be fed with the remains of the clos d' ecarissage whatever they 

 may be. 



" That, however comprehensible may be the repugnance of man 

 to consume meat or milk from cattle, pigs, sheep, or fowls, affected 

 with contagious diseases, there is in reality no danger in his eating 

 cooked flesh or boiled milk, furnished by these animals." Journal de 

 Chimie Medicale, March, 1852.
