(The facts in reference to ‘‘ The Bohemian Skull” (see ante, page 43) having since the reading 
of the paper been made public elsewhere, Dr. Wilson furnishes the following paper for 
publication in lieu of it.] 
In a communication made to the Canadian Institute in 1871, and 
subsequently printed in the Canadian Journal,* I drew attention to 
an interesting discovery, supposed to indicate the traces of a left- 
handed workman of prehistoric times. The Rev. William Green- 
well carried out a series of explorations of a number of flint-pits, 
known as Grimes’ Graves, near Brandon, in Norfolk ; and in a com 
munication to the Ethnological Society, of London, on the subject, 
he states that in clearing out one of the galleries excavated in the 
chalk by workmen of the remote Neolithic Age in order to procure 
flint nodules in a condition best adapted for the purpose of the flint 
tool-maker, it became apparent that, while the pits were still being 
worked, the roof of the gallery had given way and blocked up its 
whole width. The removal of this obstruction disclosed three 
recesses extending beyond the chalk’s face at the end of the gallery, 
which had been excavated by the ancient miners. In front of two 
of those recesses lay picks made from the antlers of the red deer.
