credit of being a proselyte of Darwin and Hunter, 
is abundantly shewn in his therapeutic disquisitions, 
and in such of his practical lecturesas I have had the 
pleasure to hear. On the subject of blisters, dis- _

bleeding and evacuants which are particularly 
necessary in fevers of high action and local pain.
