Death 130th day of disease. Up to the 33rd day of the treatment, the red corpuscles
were increased, white diminished, and coarsely granular cells increased, showing a healthy
condition of the animal, but from that date until the 86th day there was a rapid decrease in
the number of red corpuscles and coarsely granular cells. At death, there was a marked
increase in the number of red and white corpuscles, and an entire absence of the coarsely
granular cells.

After the administration of Iron, there was an increase 4.4 per cent. in the number of
red corpuscles, but after an attack of Lymphangitis, their number was rapidly reduced by
33.63 per cent. During the last 18 days the red corpuscles increased 16 %, but the
white rapidly decreased, until at death the white were represented by 9 % of the corpuscles
at the first examination, and the coarsely granular cells had been entirely absent for more
than two weeks.
