process elsewhere, e.g., abscess of liver; or it may be 

 part of a general infection, such as typhoid fever. 



In either the sputum or nasal secretions, or both, there- 

 fore, are always found the infectious agents of diphtheria, 

 influenza, scarlet fever, whooping-cough, mumps, rabies 

 (hydrophobia), pneumonia, tonsillitis, bronchitis, pulmo- 

 nary tuberculosis (consumption), tubercular laryngitis, 

 cerebro-spinal fever (secretion from nose ?) , measles, acute 

 glanders (farcy), actinomycosis, small-pox, leprosy (when 

 lesions are in nose), aphthous fever (foot and mouth dis- 

 ease,) echinococcus disease of the lungs, S3^hilis (primarily 

 in mouth), and typhus fever. Parasites — eggs of Para- 

 gonimus {Distoma) Westermanii, in parasitic haemoptysis. 



In the same secretions, but only when the respiratory 

 passages are also involved in the disease, are found the 

 microbes of typhoid fever, anthrax, bubonic plague, 

 actinomycosis, amoebic dysentery (in perforation of 

 abscess of liver into lung), syphilis (secondary), tuber- 

 culosis, leprosy, glandular fever (?), gonorrhoeal stomat- 

 itis (child infected during parturition). In the vom- 

 itus, it is always to be remembered, such organisms as 

 cause intestinal diseases, or intestinal parasites and their 

 eggs, may be ejected. Thus cholera spirilla have been 

 found in vomited matter, as well as the eggs and even 

 segments of tape- worm.
