- M. PASTEUR,S LATEST.

Louis Pasteur, the great French chemi st has done much wonderful and valuable work. The silk industry of the south of France was threatened with ruin by disease that was destroying the silk-worms, killing them in the egg or at a later stage of growth. M. Pasteur found the cause of the trouble and restored it's wealth to the desolated silk dis trict." Accepting the theory that some dis eases are caused by minute organisms in the l fluids of the body, M. Pastenr made experi- ments with diseased animals, and discovered that these organisms trsnsplanted from their natural habitation to the bodies of other animals, or to fluids prepared for the purpose, would live and multiply, undergoing, however, some changes, so that, when transferred again to an animal of the same species as that from which they were first derived, they cause disease of like character to the original. but milder and less malignant, and that the ani- nal having suffered this mild form of the disease is permanently protected against the disease in it's virulent form. In this way he found 8 preventive of hen cholera and also of deadly carbuncular disease which was
 
 of France. It is now announced that this wonderful and benefcsnt man has applied his discovery to hydrophobia He found out that the hydrophobia poison loses it's intsnsi- ty by transmission to certain animals and in creases it's intensity by admission to other animals. With the rabbit, for instance the 0t'us ra6tQue increases; with the monkey it decreases. He took virus from the brain of dog that had died of acute hydrophobia. With this virus he inocuIated monkey. The monkey died. Then with the virus-already weakened in intensity-taken from this monkey he inoculated a second monkey. Then with the virus taken from the second monkey he inoculated third monkey, and so on until he obtained virus SO weak as to be almost harmless. Then with this almost harmless virus he inoculated 8 rabbit, the virus being at once increased in intensity Then with the virus from the first rabbit he inoculated 8 second rabbit, and there was another increase in the intensity of the virus. Then with the virus of the second rabbit he inocu1ated third rabbit. then a fourth, until the virus had regained it's maximum intensi- ty. Thus he obtained virus of different de- grees of power. He then took a dog and I inoculated him, first with the weakest virus from the rabbit, then with the virus from the second rabbit, and finally with the | rabbit virus of maximum intensity. | After few days more he inocuIated the dog l with virus taken directly from the brain of 6 dog that had just died of acute madness
 The dog upon which he had experimented l proved completely unacceptable to hydro phobia. The experiment was frequently repeated, always with the same successful result.
 Other interesting experiments in the same 1 line were made until M. Pasteur was satis- fled that he had discovered preventive of the dreadful hydrophobia. So sure was he of his position that he did not hesitate to try his treatment on himself, first inocuIat- 1 ing himself as above described, and then al- lowing himself to be bitten by rabid deg. | He wants to have the French government test his discovery by experiments on volun- ! tary subjects or condemned prisoners, and 1 give an official judgment upon his process through commission composed of eminent men of science. His statements seem to be well substaatiated, and if he has found 8 preventive of hydrophobia his name ought l to and will be held in lasting honor.
