These  experiments  show  that  the  seedlings  growing  in  the  solu- 
tion containing  but  -oi  per  cent,  alcohol  still  grew  slightly  less  than 
those  in  the  solutions  containing  -1  per  cent,  and  -5  per  cent,  alco- 
hol, and  that  in  the  solutions  containing  over  5  per  cent,  there  was 
no  further  growth. 
In  the  experiments  tabulated  on  p.  476  aqueous  solutions  of  strych- 
nine nitrate  (Merck's)  containing  the  following  amounts  of  the  alkaloid 
to  50  c.c.  of  distilled  water  were  used:  ^  grain,      grain,  ^  grain,

It  is  interesting  to  note  that  in  the  above  experiments  the  maxi- 
mum growth  of  both  the  Pisum  sativum  and  Litpinus  albus  occurred 
in  the  solution  containing  ^  grain  of  the  alkaloid,  while  those  in 
solutions  of  weaker  strength  grew  slightly  less.  The  solution  which 
proved  toxic  contained  1  grain  of  strychnine  in  50  c.c.  of  distilled 
water. 
In  the  second  table  on  p.  476  the  lengths  of  the  roots  at  the  end 
of  the  second  twenty-four  hours  are  given.
