rofessor Castan has recently collected, in the _Montpelier
Medicale_, a variety of facts, which seem to show that tuberculosis may
be communicated from a diseased to a healthy person by transpiration,
breathed air, and living together (_Press and Circular_, March 10,
1869). In regard to the inoculation of tubercle, we have reference to
the well-known experiments of M. Villemin, of the Hopital Val-de-Grace,
Paris. In this connection we may record an instance of recent medical
heroism. M. Lespiaud, attached to the surgical department of the
Val-de-Grace, in presence of several of his colleagues, extracted
granular matter from the body of a phthisical subject, and introduced it
under his own integument. This zealous investigator into the etiology of
tuberculosis has thus exposed himself in a courageous way for the
benefit of science, to the effects of a most dangerous and merciless
disease.

753.

P 103. See _Lancet_ for March 6, 1869, p. 337, for report of discussion
in the Pathological Society of London upon the physical degeneracy
resulting from procreation during intoxication. Authorities could be
cited at length upon this subject, but it is not necessary. See
Huleland's _Art of Prolonging Life_, p. 207.
