began to tremble. She did not remain long on her feet, but lay down as 
though exhausted. Trembling was aggravated with the additional symp¬ 
toms of vomiting, frothing at the mouth, grating of the teeth, and labored 
breathing on the 16th. She died at 1:30 P. M. 
Blood Study. On May IS a study was made of the blood to determine the 
normal condition of this lamb’s blood with the following result: 
Numerical count: 
Erythrocytes .. 13,040,000 
Leucocytes . 14,000 
Differential count: 
Neutrophiles . 20 per cent 
Lymphocytes, large . 16 per cent 
Lymphocytes, small . 61 per cent 
Eosinopliiles . 3 per cent 
On June 15, after the symptoms had developed, another study of the blood 
was made with the following results: 
Numerical count: 
Erythrocytes . 14,000,000 
Leucocytes . 11,000 
Differential count: 
Neutrophiles . 46 per cent 
Lymphocytes, large . 2 per cent 
Lymphocytes, small . 52 per cent 
Eosinophiles . None 
This shows an increase of neutrophiles with a corresponding decrease of 
lymphocytes. The eosinophiles have disappeared. There is a decrease in the 
total number of leucocytes, and apparently a slight increase of erythrocytes. 
Protocol. There are no cutaneous or subcutaneous lesions to be found.
