The British Empire.--This Is the four
bundredth wear since the publica ton Of
that epochmaking treatise, entitled
sExercitatio Anatomical De Mott Condis
ct Sanguinis," the treatise namely IN
which William Harvey expounded ms
discovery of the circulation OF the
blood.
vast deal Of ink has been spilled In
attempting 10 diScredit Harvey's clam
10 that supreme distinction In the nelo
of physiology, but quite in vain. TO ps
sure. the Frenchman Sylvlus tdled loool
doscrihed the values of the veins, and
that great Spaniard Servetus who, IL
will be remembered. was for his enorls
toward human enlightenment duiy re-

ing at the stake in 1851 partially un-
derstood and described the lesser or
pulmonary circulation, but Sylvius oio
not grasp the significance OF the valves
and az / have intimated. Servetus' con-
cention of the lesser circulation was
very imperfect. and finally no one before
Harvey so far as the evidence goes
had the faintest inkling OF the grcateF
or systematic circulation. u.

human achievements most nearly APP

Before Microscope.
The microscope had not yet been IN"
vented so that Harvey could moi see tne
capillary channels by which the blooo
masses from the arteries to the veins.
THE mental leap was, however, the more
notable for this gap As some one nas
said the existence of the channels flrs'
seen by Marcello Malpighi, IN 1901
through the newly invented microscope
was as clearly pointed to by Harvey
