[1718: 262]
Sir, I receiv'd yours of March 20th, in an answer whereto I can only tell you as to the first particular, about Bisulc and Quadrisulc, that the Reasons why I conjecture the Rhinocerot and Hippopotamus to be 4drisulc are (what I intimated before) the bigness and position of the ouitward hoofs, as they are represented in the sculps, bot being set at that distance
[263]
as they are in Bisulc animals; and the authority of Columna, as to the Hippopotamus who (had the hind Ungulae been like to, and situated in like manner, as in other Bisulc animals), would never have made such a remark upon it, viz. that its feet were Quadrisulc.
