38 THE BIOLOGY OF DAILY LIFE. 



English, and in which the latest collected account of 

 the results of German, French, Italian, Swedish, and 

 American research in fact, a record of the work of 

 physiological laboratories of the world is given in a 

 short form. 



" Micrococci occur always normally in large 

 quantities in the fluids (saliva and mucus, &c.) 

 of the nasal and oral cavities, pharynx, larynx, 

 and trachea. They are derived no doubt from 

 the atmosphere. On the papilla? filiformes of 

 the tongue they form in some cases large 

 masses. Pasteur has inoculated rabbits with 

 the saliva of a child that suffered from hydro- 

 phobia, and having cultivated artificially the 

 micrococci present in this saliva, thought to 

 have discovered that a micrococcus (microbe 

 specidle) is the cause of hydrophobia. 



" That saliva of the healthy dog and of man 

 inoculated subcutaneously into rabbits, some- 

 times produces death in these animals 

 (Senator), had entirely escaped his notice, 

 and Sternberg (Bulletin of the National Board 

 of Health, U.S.A., Ap. 30th, 1881) has 

 proved this in an extensive series of experi- 

 ments. His own saliva proved sometimes fatal 

 to rabbits. They die of what is called 

 septicaemia, and Sternberg thinks it is due to 

 the micrococci ; but this is not to be considered 

 as satisfactorily proved. 



"All these micrococci stand therefore on 

 no definite causal relation to the respective 

 maladies, but are probably only of secondary 

 importance." (Klein, pp. 68 and 69.)
