heating of the solution to above 50° C, but below 75° in the case’

The conclusions therefore arrived at jaime. the Jequirity 55 
poison may be thus summarised :— 
ft. The toxic action of the jequirity (Abrus preatr ius) 
_ resides in two proteids—a globulin and an albumose . 
2, Both these proteids produce nearly - -the same effects, 
namely, local edema and ecchymosis at the seat of inoculation, 
with ecchymosis in the serous membranes, and gastro-enteritis, 
the blood in many cases remaining fluid. The general symptoms — 
are a gradual sleepiness, ending in Foote! with. ae onset of | 
" . igor mortis. 
3. That both portions have nislonneghe Si effect on 
the body temperature ; the globulin, atthe same time, producing 
pidity of breathing, while the albumose does not have this 
effect to the’same degree. : = 
4. That the activity of both proteids i is destroyed. by a tem- 
75° and 80° C. and the albumose at 85° C., while temperatures 
“below these a but above 50° C. diminish the gers
