9:00 A.M. following, death of the filament, but with no 
plasmolysis 
Check experiments on a new filament with the same toxic doses 
were used, with similar results. 
TRUE (20), working on Lupinus albus, found for inorganic acids 
that the H ion produced the greater toxic effect on the vitality than 
the Na ion of the sodium salt. The same was correspondingly true 
for organic acids, with the toxicity proportional to the dissociation 
of the H ion. It may be noted in passing that the resinic acid 
would probably be more toxic than the potassium salt. 
In the process of steam distillation of the resene condensation 
at 10° C. is not complete. Unless the apparatus is inclosed in a 
hood with a good vent, the room soon becomes permeated with the 
volatile resene. It has a characteristically sweetish odor, very tere- 
binthine in nature. During a period of 3-4 hours the writer was 
in the immediate vicinity of a resene still, with the room tempera- 
ture at 22° C. and the condenser at 10°. Certain pains developed 
under the eyes with sharp, shooting pains in the occipital region. 
Also a dull pain developed in the spinal cord, mostly in the lumbar 
region. Within a short time a high fever arose (102—104° F.), alter- 
nating with chills. At times, as the chills abated, the blood coursed 
through the head, seemingly laden with fire. A tickling sensation
