Filaria oculi, the name applied to it, is rare in temperate 

 climates, but is said to be common in India. The life-history

MONDAY AFTERNOON LECTURES.

 season in the Y. M. C. A. Hall, corner of Queen and O'Connor

 special object in view of reaching those interested in natural 

 science studies, and pointing out to them the best methods of
