CORRECTION. P. 150, lines 15-22, Dr. Bryce's report should read: "All the 

 skulls were dolicho-cephalic the highest index being 75 '2 the lowest 66 '6. They 

 possesed characters closely resembling those of the skulls found in the long Barrows 

 in England- -and two exactly realized the description of the Kumbecephalic skulls 

 first described by Sir Daniel "Wilson. In other respects the skeletons shewed 

 primitive characters especially in the case of the Tibiae which in the majority of 

 instances were platycnemic, 



Thus in Neolithic times the inhabitants of the Clyde valley were of the same 

 primitive race as that which built the long Barrows in England, and were character- 

 ised by long heads and short stature. They had not begun to use bronze. They 

 still buried their dead in chambered cairns and were already skilful in the manufac- 

 ture of pottery."
