Having seen the statement in one of the newspapers that this skull was not genuine, but a joke played on Professor Whitney, I wrote to Professor W. Denton of Wellesley, Ma.s.schussetts, on 19th March 1875, inquiring about it. A few days later I received from him the statement that he had visited the place where the skull was found; that certain persons a.s.sured him that Professor Whitney had been the victim of a joke. Yet these persons had never seen the skull, and were prejudiced against Professor Whitney. The persons who were best informed had every reason to believe the statements made by Professor Whitney were true.

The skull is a very remarkable one, and stands alone for the enormous size of the orbits, and I have good reasons to believe it to have been found as stated.
