WHAT  HAY-FEVEE  IS

All  forms  of  hay-fever  terminate  with
the  first  frost,  and  the  long  interval  in
which  one  may  suffer  is  shown  by  the  first
case  above  from  May  1st  to  cold  weather.
In  the  United  States  some  who  are  at-
tacked in  May  recover  by  the  1st  of
July;  some  attacked  in  Jnly  are  well  by
the  15th  of  Angnst;  some  attacked  in  Au-
gust recover  by  November  1st,  while  some
unfortunates  suffer  throughout  the  period
from  May  to  November.  The  June  type
may  be  followed  by  a  September  visita-
tion or  become  a  permanent  August  at-
tack, or  the  August  type  may  disappear
in  certain  individuals  and  reappear  as  a

June  cold.
