624 CIRCUMVOLUTIONS OF THE CEREBRUM OF CANIS DINGO, 



of Anatomy.* 5. That similar operations on native women have 

 been reported lately from other places of Australia.! 



Remarks about the Circumvolutions of the Cerebrum of 



Canis dingo. 



By N. de MiKLouno-MACLAY. 

 [Plate V.] 

 Without going into a detailed description of the gyri and sulci 

 of the brain of the Dingo, a glance of the same (fig. 1.) and even 

 a superficial comparison with the circumvolutions of another dog 

 (fig. 4), proves, that the gyri of the former are more numerous 

 and complicated than that of the later. It is true that on the 

 plate are figured the Brains of two very extreme representatives 

 of the species Canis. The one is that of the Dingo, the wild dog 

 of Australia, the other the dog of New Guinea (from the Maclay 

 Coast). The mode of life of both helps to explain the differences 

 of their brains. 



The dingo depends upon his skill to provide himself with 

 sufficient food by hunting, which requires often the full use of his 

 intellect. Many of the gentlemen present here know far more 

 than myself about the intelligence and cunning of the dingo ; 

 therefore, having no experience of my own to add about this 

 subject, I will say a few words about the Papuan dog. 



*Dr. Roberta in his travel from Delhi to Bombay (I found it mentioned in 

 Muller's Archiv., 1873.) speaks about a female eunuch, who had the ovaria 

 cut out ; she had no breast, very little adipose tissue on the Mons veneris 

 which was hairless, the backside was manlike, she had no menstruation, and 

 no sexual inclination. 



tl know from Mr. H. Gilliat, that Mr. Suttor has told him of having seen 

 women similarly operated on, among the blacks on the Herbert and Mulligan 

 Rivers, and that another gentleman had assured him of the same fact. I 

 have heard from Mr. Duf aur, that he had noticed in the diary of Hume, a 

 reference lo a similar practice among the blacks.
