THE DISEASES AND DISORDERS OE THE OX. 



in other animals. It also occurs, though very rarely, in sheep 

 and pigs. In solipeds it is not often seen, and in carnivorous 

 animals it is almost unknown. The disease is also met with in 

 poultry, and it has been suggested that in some cases the infection 

 has been conveyed to them by the medium of human tubercular 

 sputum. Strange to say, fowls seem to be not so capable of 

 being inoculated or infected with bovine tuberculosis, as of 

 becoming affected with tuberculosis of a mild type if inoculated 

 with or fed upon human tubercular matter. 



The malady has been induced in many animals of different 

 species by inoculating or feeding them for a time with tuber- 

 cular matter obtained from animals affected with the disease. 

 Guinea-pigs and rabbits may be inoculated either with human

 The above picture represents a cow suffering from tuberculosis. The poor 

 cow is, indeed, a pitiful object ; but how much more so is a human being when 

 afflicted with this truly dreadful complaint, only those who have repeatedly seen 

 them so affected can know. How earnestly, then, ought we to do all in our 

 power to find out a means of combating this awful malady ! 



tuberculosis or with ' bovine tuberculosis; but the diseases 

 induced in the two cases are perhaps not identical. Dr. Klein 

 holds that human tuberculosis is not exactly the same disease 

 as bovine tuberculosis, and it has not as yet been absolutely 

 proved that tuberculosis can arise in man from eating the flesh 

 or drinking the milk of cattle afilicted with tuberculosis. It 

 has been well established that bovine tuberculosis is transmissible 

 to pigs, cattle, sheep, monkeys, rodents, &c., by tubercular 

 matter, and it is probable, although it has not been actually 

 proved, that human beings can contract human tuberculosis by 

 feeding on flesh or milk of tuberculous animals.
