 subject : — " For several years the Mosquito has been accused of 

 being the agent by which intermittent fevers are distributed, 

 but the allegation has not yet been satisfactorily proved, 

 especially as the cause of fever has not j'-et been definitely ascer- 

 tained. It is probable that the gregarine-like organisms which 

 live in the blood and attack the blood-corpuscles are the cause, 

 but there still remains something to be found out with regard 

 to their multiplication and distribution. When that is done we 

 shall be able to judge of the part .Mosquitoes play iu the spread 

 of fever and disease. The able Italian Zoologist Grassi has 

 proved that flies pick up the eggs of the human thread worm, 

 also fungus spores, and they are likely to drop them again, 

 in their excrement, in a vivifiable condition. If they exercise 

 such an importa'nt part in the distribution of the thread Avorm 

 is it not probable they also distribute the germs of contagious 

 diseases ? M. Eanvier in 1887. before the French Acadamv of
