Two remarkable cases of this peculiarity were afforded by tibiae taken by me from a mound on the Detroit river. In one of those unique specimens the transverse diameter of the shaft is 0.42, and in the other 0.40 of the antero-posterior diameter, exceeding, I believe, any platycuemism which has been observed before or since in any part of the world. In communicating these facts to the American Naturalist, not long afterward, I claimed that the last mentioned case "may be considered as the flattest tibiae on record." (See American Naturalist, October, 1871.) Both of these bones are strongly marked with the saber-like curvature, also a characteristic of the chimpanzee, as are likewise many others of the tibise from the vicinity. The majority of the tibiae present the flattening, which is an exception to the facts as noted in other sections of the United States where it is supposed to pertain to "only about one-third of all the individuals observed." In fact it is an exception to find a tibiae from our mounds along the Detroit destitute of this peculiarity; and where one is found it is generally of later burial and consequently of less ancient origin.
