DISEASES AND ENEMIES.

which it would be premature to give any details, 
beyond that phenol is certainly, to some extent, 
beneficial. 
Finally, are these germs indicative of disease ? 
Emphatically they are, in every case. Bacteria are 
not found in healthy tissues, nor in healthy blood ; 
and, since I may be reminded of an editorial in the 
British Bee Journal of May 13th, 1886, which has 
somewhat confused the minds of some, I will simply 
give three references to the Royal Microscopical 
Society s Journal. June, 1886, page 536: “Pasteur’s 
experiments have shown that the tissues of animals 
are the most perfect filters known, neither permitting 
the entrance, nor tolerating the existence, of any 
foreign material, unless the tissues are diseased.’^ 
August, 1886, page 665: “Herr G. Hauser has sub- 
jected this question to fresh examination, with the 
following results : In the living tissues and tissue-fluids 
of healthy animals, he finds neither pathogenic nor 
any other description of bacteria.” December, 1886,. 
page 1036 : “ Herr J. von Fodor has examined the blood 
of healthy living, or recently killed, animals, for the 
purpose of ascertaining if bacteria develop. The blood, 
placed in sterilised flasks, with the usual precautions, 
was kept at the temperature of the room, or in incu- 
bators at 95° to 98° Fahr., for several weeks, and, after 
excluding errors from accidental impurities, the author 
found that the blood contained no bacterial germs 
capable of development. 
“The author, furthermore, injected non-pathogenic 
bacteria in enormous quantities into the jugular veins 
of living rabbits, and found, in consonance with the
