be attractive, so that there is less danger of poisoning,’ although 
Chesnut and Wilcox report a death in cattle from eating Delphinium 
glaucum in September.” The great danger early in the season seems 
to arise from the fact that the Delphinium appears early in the 
spring, and the ground may again be covered with snow, so that it is 
the only green plant in sight, and therefore when in an especially 
poisonous stage it 1s eaten by cattle. 
A rabbit weighing 2,409.66 grams was fed January 28, 1907, with 
a concentrated aqueous extract corresponding to 16.66 grams of the 
dried plant in the second stage. No symptoms resulted. On Janu- 
ary 30 the animal weighed 2,377.15 grams. 
On January 28, 1907, a second rabbit, weighing 1,658.35 grams, was 
fed with a similar extract of 33.33 grams, but no symptoms resulted. 
Two days later the animal still weighed 1,658.35 grams. 
On February 1, 1907, the first rabbit was fed an aqueous extract of 
80 grams, and it died in 583 minutes with convulsions. Previous to 
death, paralysis of the voluntary muscles was well marked. The 
stomach of this animal was markedly reddened. 7 
A rabbit weighing 1,984.41 grams on February 6, 1907, was starved 
24 hours and then fed an extract of 50 grams of the same plant at 
9.45 a.m. At 11.50 a. m. the animal was dull and was lying with 
its chin resting on the floor; at 12.25, legs paralyzed; 3.04, the animal 
urinated, chin still resting on the floor; 3.57; the animal could push 
itself around with hind legs. The following day the rabbit appeared 
normal. On February 11 it weighed 1,899.39 grams; February 12. 
1,956.07 grams; February 18, 2,012.75 grams; March 11, 1,984.41 
grams. 
On February 13, 1907, a well-fed rabbit, weighing 2,097.77 grams, 
which had been in the laboratory for some time, was fed by stomach 
tube an aqueous extract of 50 grams of the same plant. This animal 
was observed continuously for 6 hours and appeared perhaps only 
shehtly duller. He ate during the night, and weighed 2,119.94 grams 
on February 14. During the night no stools were passed. On Febru- 
ary 16 this rabbit weighed 1,970.24 and on February 21, 2,012.75 
grams. 
The urine passed the first 24 hours after feeding was alkaline. 
Some of this was shaken with chloroform and on evaporation was 
taken in acid water. On evaporating off the acid, the watery solution 
was injected subcutaneously into a guinea pig weighing 467.76 grams, 
but produced no symptoms. The urine secreted in the following 24
