of the cranial cavity. The entrance to the left ear is compressed 

 and the condyles of the occiput are thrown out of tlieir hori- 

 zontal position. 



The question naturally presents itself, whether the capacity of 

 the cranium, or in other words, the size of the brain, is dimi- 

 nished by this distortion ? This can be answered only by actual 

 measurement. The following table gives the capacity of eleven 

 crania from different Oregon tribes. 



Boston Society for Medical Improvement, and described in the 

 Catalogue, and the others, with the exception of the last, are 

 quoted from the Catalogue of Crania in the Collection of the late 

 Dr. S. G. Morton. 



The capacity of the skulls of the North American Indians 

 generally, as stated by Dr. Morton from the measurements of one 

 hundred and sixty-one crania, gives an average of 84 cubic 

 inches. The average capacity of eleven distorted heads deduced 

 from the above table is a little less, namely, 81f cubic inches. 



It does not appear that the Flatheads are less intelligent than 

 other North American savages. Dr. Pickering describes them 

 as even more intelligent, and as having made greater advance- 

 ment in the arts than the hunting tribes of North America. 



Dr. Kneeland exhibited the cervical vertebrae of the 

 Snapping Turtle, (Emysaurus serpentina^) for the purpose 

 of showing the homologies of the "odontoid process" of 

 the second cervical vertebra.
