intact; they contain an opal liquid, a little suspicious, slightly 
albuminous, in which numerous small refringent motile bodies 
are moving; they are so small that they can be distinguished 
only by a high magnifying power (about 2000 diameters) and 
yet their form cannot be made out. 
June 29, 8 A. M., we inoculate a Breton heifer (No. i) by 
subcutaneous injection, back of the left shoulder, with five 
drops of the opal liquid taken on 27th from one of the collodion 
bags. These five drops were first diluted in 2 c.c. of sterilized 
bouillon. 
Up to July 7th nothing abnormal is observed on the inocu¬ 
lated cow ; she is gay, has good appetite ; her temperature re¬ 
mains in the neighborhood of 38.5° as before the injection. 
July 8th, the temperature is 39.1° in the morning, 39.7° in the 
evening ; from that date it keeps rising slowly and gradually 
to reach 41.3° on July 19th. 
No. I. —Breton heifer, 10 months old, inoculated June 29, 1896, with 
5 drops of pleuro-pneumonic culture in collodion bag. 
July 7, there was a small swelling at the point of injection ; 
on a surface as broad as the palm of the hand, the skin seems 
to be raised, it has lost its suppleness, is a little warm and sore.
