Clinical Notes. The first symptoms appeared July 13, when the respira¬ 
tion was slightly jerky. On the 14th, she lay with head and neck extended and 
jaw resting upon the ground. After standing for about a half-minute, she 
would begin to tremble as noted in all the other cases. As soon as trembling 
began, she would lie down. In the afternoon the symptoms were more aggra¬ 
vated. She went into a state of coma during the night before she died, and 
death occurred July 15, at about 8 A. M. 
Blood Study. On May 18 a study was made of the blood of ewe 168 to 
determine the normal condition prior to the feeding of white snakeroot. The 
following is the result of this study: 
Numerical count: 
Erythrocytes . 8,040,000 
Leucocytes . 14,000 
Differential count: 
Neutropliiles . 46 per cent 
Lymphocytes, large . 4 per cent 
Lymphocytes, small . 45 per cent 
Eosinopliiles . 2 per cent 
Mast cells . 3 per cent 
Hemaglobin . 72 per cent 
On July 14 a study of the blood was made with the following result: 
Numerical court: 
Erythrocytes . 9,540,000 
Leucocytes .. 9,000 
Differential count: 
Neutrophiles . 45 per cent 
Lymphocytes, large . 14 per cent 
Lymphocytes, small . 39 per cent 
Mast cells .. 2 per cent 
Hemaglobin .... 72 per cent 
There was thus a slight increase in the small lymphocytes at the expense 
of the large lymphocytes, a slight increase in the erythrocytes, and a numer¬ 
ical decrease in the leucocytes. The hemaglobin remained normal. 
Protocol. Externally the body presents nothing worthy of note. 
The Thoracic Cavity .—The lungs appear normal and collapse when the 
thorax is opened. There is neither pneumonia, broncho-pneumonia, nor pleu- 
ritis. The color of the lung is pale salmon. No excess of fluid is found in 
the thoracic cavity. 
The Heart .—There is an excessive amount of pericardial fluid. Petechia- 
tion of the epicardium in the region of the coronary arteries and at the base 
of the heart is noted. The heart is filled with dark, coagulated blood. There 
are no agony thrombi and the muscles appear pale in color. 
The Abdominal Cavity .—An excessive amount of serous fluid exists in the 
abdominal cavity. Muco-enteritis involving the abomasum and duodenum and 
a portion of the jejunum is present. Stomach worms are found in the abo¬ 
masum. The small and large intestines are affected with nodular disease. 
The large intestines otherwise appear normal.
