expelling some gas from the stomach. At 1.42 the pulse was 120. 
At 1.46 the pulse was 104. At 1.47 she raised herself without much 
effort. Plate XII, figure 6, shows her at this time. At 1.52 she was 
trembling, her back was arched, and she was stepping about uneasily. 
There was considerable salivation, and there was and had been for 
some time dribbling of urine. At 1.55 the trembling was very much 
decreased. She walked with a stiff gait and at 2.04 seemed to be over 
the attack. No further symptoms were noted. 
EXPERIMENTAL FEEDING OF DELPHINIUM BARBEYI TO CATTLE IN 1911. 
Because Delphinium* menziesii disappears about the first of July, 
the station work in the early part of the seasons of 1909 and 1910 
was very largely concentrated on this plant, and most of the work 
on Delphinium, harheyi was done after the plant was in blossom. As 
the season in 1911 was about two weeks later than in 1910, Delphinium 
harheyi in the middle of July in 1911 was in about the same stage of 
development as at the first of July in 1910. In addition to confirming 
the work of the preceding seasons on symptoms and remedies, especial 
attention was paid to the poisonous effects of the plant in its early 
stages. Two experiments were made of feeding the dried plant, as it 
was desirable to determine whether the plant lost its poisonous 
properties by drying. 
Twenty-six feeding experiments were conducted on 22 different 
animals, and the greater poisonous effect of feeding the larkspur 
within a short period of time was much more clearly brought out 
than in the preceding seasons. 
The experimental work with remedies made it possible to deter- 
mine quite definitely the quantities of physostigmin, pilocarpin, 
and strychnin which could be used to the best advantage. 
Table III shows the results of the feeding in a summarized form 
and they are discussed later in the paper. None of the cases are given 
in detail, since the feeding experiments were conducted in the same 
manner as in the preceding years and the general results were the 
same. 
EXPERIMENTAL FEEDING OF DELPHINIUM MENZIESII TO CATTLE IN 1909. 
During the season of 1909, nine experiments were made of feed- 
ing Delphinium menziesii, the experiments commencing on June 24 
and continuing until July 25. Part of the material used was col- 
lected around the station, and was to a large extent mature, the 
plant being in flower and in some cases containing seeds; the re- 
mainder was obtained at Kebler Pass, and consisted of small plants 
before flowering. The whole plants, including roots, stems, and 
flowers, were fed to some animals, while in other cases only the 
tops were fed, and in still others the roots ground up with grain.
