A boy, aged twelve years, of weak constitution, was suffering from
frequent and intense attacks of whooping cough. At a time the fits
were so vehement that blood came out of his eyes and mouth. The case
was a severe one, and I thought it would very likely end fatally. I
prescribed several medicines, and even subcutaneous injections of
morphine, but without any avail. I then tried for the first time the
counter-irritation on both sides of the neck, and this means acted
like magic. In four or five days the patient recovered, and was able
to go to school. Since that time I have been applying the same
treatment, either on the right side only or on both, with the greatest
benefit.--_Br. Med. Jour._

DEVELOPMENT OF THE EMBRYO.
At a recent meeting of the Physical Society, Berlin, Prof. Preyer
spoke on reflexes in the embryo. His researches extended over many
classes of animals. As representing mammals, guinea pigs were chiefly
used; and for reptiles, snakes; while in addition the embryos of
fishes, frogs, mollusks, and other lower animals were also employed.
But of all animals birds are most suitable for embryological
observations, inasmuch as with due precautions the development of one
and the same individual can be followed for a considerable time.
Birds' eggs can be incubated in a warm chamber, and by removing a
portion of the shell and replacing it by an unbroken piece from
another egg, it becomes possible to follow the daily development of
the chick and to experiment upon it.
