58 STOCK-POISONING PLANTS OF MONTANA. 



was unable to rise, and it remained in this condition until after 7 p. m. 

 The gurgling-, labored respiration and sighing continued throughout 

 that time, but the frothing ceased after an hour or so. The rectal 

 temperature at 5.25 was 101.8. The animal had sufficiently recovered 

 by the next morning to go out and graze with the remainder of the 

 little band of which it was a member. 



JExpermient 11. — Precisely the same amount of the same extract 

 used in Experiment 10 was fed in the same way at 2.55 p. m. to a 

 sheep weighing approximately the same^ but before withdrawing the 

 tube 25 cubic centimeters of a solution containing 1 per cent each of 

 the permanganate of potash and sulphate of aluminum was poured 

 into it and this was washed down into the stomach with water. A 

 deep sleep soon came over the animal from which it did not awaken 

 until after night, but although watched very carefully until past 7.15 

 p. m. it did not exhibit any of the symptoms recorded for the previous 

 experiment. 



Experiment 1'2. — On May 21 two healthy sheep were placed in a 

 corral and fed, respectively, 30 plants of death camas without the 

 bulb and 20 with the bulb, or approximately 105 grams and 220 grams 

 of these materials. These two sheep were not hungry and would 

 not of their own accord eat the death camas when placed in a box near 

 them. When the sheep were held, however, and the death camas 

 placed in contact with their lips they ate it readily. One hour later 

 symptoms of poisoning began to be manifested which were exactly 

 identical with those previously observed in the field. The quantity of 

 death camas fed to these two sheep was not quite sufficient to cause 

 death, although they were seriously poisoned and required three days 

 for a complete recovery from the effects. 



Experiment 13. — On June 8 two other sheep were fed each 40 death 

 camas plants with bulbs, or approximately 410 grams. The same symp- 

 toms were manifested in a more violent form, and both sheep died 

 after the lapse of five and six hours respectively. The death camas 

 plants fed to both these sheep were in full flower. At the time 

 of this experiment the plants at the lower altitudes were already 

 in seed and the leaves and stems were yellow and shriveled, but 

 the plants used were collected at an altitude of about 6,000 feet, 

 where they were in the prime of flowering. The plants employed in 

 both experiments were therefore as nearly as possible in the same 

 stage of growth. As these experiments were conducted in the field 

 the means were not at hand for weighing accurately. The weights as 

 given above are calculated from average weights as previously deter- 

 mined. It would therefore appear that the fatal dose for sheep is 

 between one-half pound and 1 pound. 



Expet'iment IJf.. — Remedies which were tried in this and the follow- 

 ing experiment included hypodermic injections of strychnine in one-
