ON THE DESTRUCTION OF BIOPLASM. 279 



28 in undisinfected open sheds. The disease was com- 

 municated to each lot by direct inoculation of the virus. 

 Only those actually inoculated, of the disinfected 

 animals fall a prey ; while of those not protected by 

 disinfection, the whole are quickly destroyed ; and, as 

 if to make indubitable proof doubly certain, and fix 

 the eye of credit on the true cause of such results, a 

 few weeks later, the remainder of those 45 disinfected 

 animals, being unwisely turned out to grass, and 

 removed from the protecting influence of the carbolic 

 acid, the plague attacked and killed the whole of them 

 within a few days. 



Having drawn attention to these facts, which dis- 

 tinctly indicate the general nature of the material 

 constituting the virus or contagion of contagious 

 diseases and the changes wrought by a powerful vola- 

 tile substance like carbolic acid, we may with propriety 

 proceed to consider more in detail the question of 

 destroying contagious bioplasm. In the first place it 

 is necessary to draw attention to the fact, that living 

 pus corpuscles may be destroyed, and their rapid 

 growth and multiplication retarded by subjecting 

 them to the influence of certain reagents (p. 290).
