The first proposition: that, in regard to a patent unsoundness, to make out a deceit there must be proof of the scienter, and a suggestio falsi, is conceded on all hands. The second, that in respect to a latent unsoundness, proof of the scienter and a suppressio veri, will be sufficient, we consider equally well settled, by the reason of the thing, and by the cases in our Court; Cobb v. Fogleman, 1 Ire. Rep. 440; Case v. Edney, 4 Ire. Rep. 93. The former was for a deceit in the sale of a female slave, who had a latent disease — cancer in the womb, but at the time of the sale was a a stout, vigorous looking woman. The defendant was silent in respect to her disease.
