LATENT, construction. That which is concealed; or which does not appear; for example, if a testator bequeaths to his cousin Peter his white horse; and at the time of making his will and at his death he had two cousins named Peter, and he owned two white horses, the ambiguity in this case would be latent, both as respects the legatee, and the thing bequeathed. Vide Bac. Max. Reg. 23, and article Ambiguity. A latent ambiguity can only be made to appear by parol evidence, and may be explained by the same kind of proof. 5 Co. 69.
