To the very hot weather that comes so often at the end of July and the
beginning of August, the traditional name of "dog-days" has been given, almost
from time immemorial. In recent years the name has given rise, in the popular
mind at least, to the idea that dogs are much more liable to go mad during
these months than at any other season of the year. The term dog-days, however,
is only our English equivalent for the Latin phrase, the days of the dog star,
when Sirius, called by the Romans also Canis, the dog, is in the ascendant—the
heliacal rising of the star occurring between July 20 and August 15.
