of this affection occur which are hardly diagnosable clinically, and 

 which may be completely cured. According to several French 

 authorities, the first indication of commencing cure is the appear- 

 ance of lymphocytes, which must therefore be looked on as a good 

 sign ; after a time the polynuclears become less and less numerous, 

 and finally the lymphocytes alone remain, and may persist for 

 some time after cure has taken place. I have watched several 

 septic cases recover, and have seen this occur two or three times. 

 The appearance of lymphocytes in an acute septic meningitis may 

 therefore justify a good prognosis.
