/ ne facts relating To the secular evolu-
lions OF diseases, says DR.. J. Netten
Radcliffe, are amongst the most inter-
estlng, II the most l6gubTiOus, in the
history of the human race. Their
great obscurlty and cOmpleXity have
iuterposed Il barrier to the construction
OF general doctrine regarding their
occurrence, but few of the salient ill.,
dlcatlons OF secular periods of morbid
evolution may be seen in this list,
chiefly according to Charles Anglada:
a. The great peslience of the 5th
century b. c., OF which the so-caled
plague OF Athens was an incident.

been OF The same nature, of the 2nd and
3rd centuries of the Christian era. At

lence disappeared. (c.) The explosion

Century after Christ, when for the first
time III history this formidable disease
assumed the character of great cpl

In TINS disease we appear to have rec
