DISEASE GERMS IN SEC RE TIONS. 1 5 z 



case, the organism is said to be " protected." But 

 such protection sometimes cannot be procured until 

 successive inoculations have been practised during 

 several months, and, as has been remarked, the remedy 

 is in many respects worse than the disease, besides 

 being, and on many grounds, quite unjustifiable. 



Living Disease Germs in Secretions. The living 

 germs of many fevers pass from the blood into the 

 secretions. The urine, the secretions from the mucous 

 membrane of the nose, mouth, stomach, and intestinal 

 canal, contain them in large numbers. There is 

 reason to think they may also escape in the secretion 

 of the sweat and sebaceous glands. In the excre- 

 ments there can be no doubt disease germs exist in 

 vast numbers in typhoid fever, in cholera, and in 

 some other diseases. Even in the milk, in the tears, 

 in the saliva, they are present. Some of the living 

 particles in the milk from a cow suffering from Cattle 

 Plague are represented in Figs. 69 and 71, plate XIX, 

 and in Fig. 70, particles of bioplasm as well as fungi 

 are seen in vaginal mucus from another animal suffer- 

 ing from the same disease. The particles of bioplasm 

 in which I believe the contagious properties reside, are 

 situated immediately under the letter d in Fig. 70. 

 Below and to the left of these particles are sporules 

 of fungi, which cannot be mistaken. Their spherical 

 form,' sharp, well-defined outline, and the high refrac- 

 tive power of the envelope, positively distinguish them 

 from disease germs.
