CHAPTER III. HISTORICAL OBSERVATIONS AND THEORIES. The historical
data herein presented are as far as possible arranged
chronologically. I offer no apology for presenting an extensive

past are all too infrequently seen in modern medical literature. If
this historical sketch of asthma serves to quicken the interest of
even a few in the subject of medical history, some good will have
been accomplished. A survey of the literature reveals that asthma
has been recognized for centuries, even from the time of
Hippocrates. Probably, however, there has been, and not very

perhaps not more than is the case with other poorly understood
subjects. The disease was first considered to be due to a spasm of
the lungs. Then later it was suggested that there might be muscle
in the bronchi and that these might undergo spastic contraction.
This theory held sway from the seventeenth century even to the
present. In the latter part of the nineteenth century the theory of
vessel turgescence of the bronchial mucosa developed and divided
honors with the muscle spasm theory. During the past decade the
theory of anaphylaxis has become popular and has given further
support to the muscle spasm theory. But a great proportion of
physicians have not been satisfied with either of the two generally

fruitless search, have failed to receive much attention.
Incidentally many interesting but disconnected facts have been
