Dr. BoRTHEN has calculated the frequency of lagophtalmus in 94 maculo- 

 anaesthetic cases to about 60 ^/o in females and 70 ^/o in males. He fur- 

 ther remarks that the lagophtalmus may occur at any time in the course 

 of the disease, having seen it develop in the first year as well as 42 years 

 after the onset.
