40 THE BIOLOGY OF DAILY LIFE. 



OPERATION OF INJECTION INTO THE BLOOD, by which 



these cruel inoculations are performed. 



Closer observation seems to show that this so-called 

 bacillus (bacillus anthrax) is nothing more than a 

 virulent form of the TORULA, which I shall describe in 

 the next chapter when on the subject of yeast, while 

 Klein has the following remark (p. 156) : 



fi Pasteur's statement that in animals dead of 

 anthrax and buried, the bacilli form spores, 

 and that these spores are taken up by earth 

 worms and carried to the surface of the soil, 

 where they are deposited with their castings, 

 and thus are capable of infecting animals 

 grazing or sojourning on this soil, is not borne 

 out by the above observations." 



Of the tubercle bacillus we read (p. 170) : 



" I cannot agree with Koch, Watson Cheyne, 

 and others who maintain that each tubercle 

 owes its origin to the immigration of the 

 bacilli, for there is no difficulty in ascertaining 

 that in human tuberculosis, tuberculosis of 

 cattle, and in artificially-induced tuberculosis 

 of guinea-pigs and rabbits, there are met with 

 tubercles in various stages young and old 

 in which no trace of a bacillus is to be found ; 

 whereas, in the same section, caseous tubercles 

 may be present containing numbers of tubercle- 

 bacilli." 



Of Koch's famous " comma-bacillus" of cholera, 

 we have the following summing-up of a long argument 



(p. 181) : 



" From all this it follows that the choleraic
