40 president's address. 



Thus Prof. Klebs, of Zurich,* giyes the results of his 

 e:^ainination of several distinct cases of influenza, and finds 

 in the blood of the patients a large number of highly re- 

 fractile, mobile bodies, in size, form, and modes of motion 

 resembling bodies which he has met with in pernicious 

 anaemia, though in greatly reduced numbers. 



This was found to be the case in an instance of fatal 

 influenza, in blood " removed with every precaution " from 

 the heart of the subject; the "monads" — for such he calls 

 them — were easily seen and demonstrated in this. They varied 

 in size, were oval in shape, and not only possessed a vibratory 

 movement, but were capable of distinct locomotion. 



It is significant that they were often attached to the margin 

 or imbedded in the substance of the blood-corpuscles. 



They were distinctly flagellated, and certainly recall to us 

 the form and manner of saprophytic forms. 



Prof. Y. Babes very carefully investigated thirty-one cases 

 of influenza with all the skill for which he is celebrated. He 

 endeavoured to show that there exists a series of bacteria 

 which, in their growth and shape, are approximate to, or 

 identical with, Pasteur's sputum bacteria on the one hand, 

 and on the other to Streptococcus pyogenes. "^ 



Herr. I. Prior examined fifty-three cases of influenza.;}: 

 Twenty-nine of these were without complications. His re- 

 searches also showed the constant j)resence of Streptococcus 

 pyogenes, and also Staphylococcus pyogenes aureus ; these were 

 present in all secretions. 



In the same way Herr E. Levy§ found that on examining 

 eighteen cases of influenza the Diplococcus pneumonice was 

 present in seventeen of these, while occasionally he found 

 also Streptococcus pyogenes and Staphylococcus pyogenes albus. 



Again, Kowalski|| examined sixteen cases of influenza, and 

 isolated three kinds of micro-organisms which he believed to
