The Bulletin 
Chemical examination: 
Phosphates—Present. 
Reaction—Faintly acid. 
Sugar—None. 
Chlorides—Present. 
Albumin—N one. 
Carbonates—Present. 
Sulphates—Present. 
The urine of suckling lambs is normally acid in reaction. The cloudy 
condition is noted in other cases of milksickness. The lamb was apparently 
normally eliminating the phosphates, chlorides, and sulphates. 
Protocol. There are no subcutaneous nor cutaneous lesions to be found. 
There are no palpable lymph glands, and the external appearance is that of 
a normal lamb. 
Thoracic Cavity. —The lungs do not collapse when the thorax is opened. 
There is present a congestive condition, but neither pneumonia, broncho¬ 
pneumonia, nor pleuritis. The lungs are dark pink in color. 
The Heart. —Petecliiation at the the base of the heart along the course of 
the coronary arteries is noted. The right side of the heart is empty, while 
the left contains dark coagulated blood. There are no petechiations on the 
endocardium or pericardium. 
The Abdominal Cavity. —There is no abnormal quantity of fluid in the 
abdominal cavity. There is no peritonitis. The small and large intestines 
are affected with nodular disease and stomach worms are present in small 
numbers in the abomasum. The small intestine appears injected, which con¬ 
dition does not exist in the large intestine. 
The Spleen. —Normal. 
The Kidneys. —The kidneys appear swollen and of a metallic appearance. 
The capsule strips off easily. Both active and passive congestion and cloudy 
swelling are present. Both kidneys weigh one-eighth pound. 
The Musculature.- —The musculature appears normal. 
The Liver. —The liver is filled with blood which drips from the sectioned 
surface. It is nutmeg in appearance. There is evidence both of congestion 
and of cloudy swelling. The liver weighs one-fourth pound. 
The Lymph Glands. —The lymph glands appear normal. 
The Brain. —The brain appears somewhat congested. 
Microscopical Examination. The Liver. —After hardening in formalin, sec¬ 
tioning, staining with liematoxylon and eosin, and clarifying in beechwood 
creosote, study was made of the cellular changes. 
The liver shows both active and passive congestion and cloudy swelling. 
The Kidneys.— Active and passive congestion are present. There is an 
occasional area infiltrated with polymorphonuclear leucocytes and with a few 
round cells. Cloudy swelling in various stages is present, thus indicating an 
acute parenchymatous nephritis. 
The Heart. —The blood vessels are congested. There is present no fatty 
degeneration. 
The Brain. —The cerebrum and cerebellum are both congested. The brain 
cells appear normal with no invasion by leucocytes. 
The Lungs. —The lung tissue shows congestion, certain alveoli are filled 
with serum and an occasional one with a few erythrocytes. 
The Pancreas —Normal. 
The Spleen. —Normal. 
The Adrenal Glands. —Normal.
