204 GORILLAS AND CHIMPANZEES 



The facial bones of No. 6 showed that the animal 

 had received a severe blow in early life, but the 

 fragments had knitted together, and the effect could 

 not be seen in the face of the ape while alive. In 

 this same picture it will be noticed that the lower lip 

 hangs down so low that the mouth is opened. The 

 lip is very massive and mobile, and in this character 

 he resembles the negro. The lower lip is much 

 thicker and more flexible than the upper. 



No. 8 is the skull of a large male from Lake 

 Izanga, which is on the south side of the Ogowe 

 River, more than a hundred miles from the coast, 

 and is one of the three centres of population men- 

 tioned. I do not know its history. It was presented 

 to me by Mr. James Deemin, an English trader with 

 whom I travelled many days in the Ogowe River ; 

 and I wish here to take occasion to express my 

 sincere thanks to him for the many kindnesses 

 extended to me. 



No. 5 is the skull of an adult female. By comparing 

 it in profile to No. 6 it will be seen that they 

 resemble, but the muzzle of the latter projects a 

 little more, and the curvature of the skull across the 

 top is less : the distance a little greater. 



Nos. 2, 3, 4 and 5 are female ; the others are all 

 male. 



Nos. 3, 4, 5, 7, 9 and 10 belong to the Liverpool 

 Museum, but are shown here for comparison. The 

 other four are all at Toronto University. 



While this series is not complete in either sex, it is 

 an excellent one for comparative study.
