 Phœnomena displayed on the dissection of the internal parts.

The ample directions which have been already offered upon this subject, (vol. iii, p. 45) will in a great degree supersede the necessity of very minute details on the present occasion. There are, however, some few phenomena that exclusively relate to the evidence of infanticide, and must accordingly receive a due share of our attention.
