344 LECTURE XII. 



some of tlie molars^ the entire crown has almost disappeared ; 

 the lower canine teeth are much larger than the incisors^ and 

 rise above the row of teeth ; the foramen inelsivum in the 

 upper jaw is very large^ exceeding in width four millimeters. 

 The ascending ramus of the lower jaw rises at a right angle, 

 and is broad and short. The muscular attachments are also 

 well marked on the lower jaw. On the right parietal bone is 

 an elongated depression as from a blow. The proportional 

 dimensions are as follows : — 



Millimeters.

lines of the occiput ..... 445

The cranial capacity, measured by millet-seed, amounts to 36 ounces, 3^ 

 drachms, Prussian apothecaries' weight." 



A similar discovery was made near Schwaan, in Mecklen- 

 burgj but the cranium is far from being so well preserved as 

 that of Plan. I might here mention some discoveries in the 

 Baltic provinces of Russia, described by Dr. Kutorga, had not 

 his authenticity been found to be rather suspicious. The skulls 

 in question were found in the Government of Minsk, in the 

 sand of an old river-bed. 



I must, however, dwell at greater length on a discovery 

 made by Dr. Spring, a distinguished professor of the Univer- 

 sity of Liege, more than ten years ago, which has not at- 

 tracted the attention it deserves, and to which I have already 

 alluded in my work KoJilerglaube und Wissenschaft. On the 

 banks of the Mouse, near Chauvaux, about one hundred feet 

 above the present level of the river, there was a small grotto, 

 or fissure, with two ossiferous beds, separated from each other 

 by stalagmite. There was first a stratum of decomposed and
