:J22 PROF. G. ELLIOT SMITH ON THE 



More recent numbers of the ' Histoire ' contain illustrations of tlie brain in the genera 

 Lemur, Sapalemur, and Lepidolemur. 



The references to this will be found below in the accounts of these genera. 



I have not seen Wernicke's short account * of the brain o^ Lemur f ulcus [inongoz], and 

 know of it merely from the passing i-eferences in three of the more recent memoir'^ 

 (Itiotcd below. 



In ISDO J. T. Oudemans gave us the best account we jiossess of the brain of the 

 Aye-aye f ; and in the same year W. Turner examined + in the light of comparative data 

 riower's above-quoted accounts of the Lemur's br.iin. 



r. E. Beddard published an account of the brain of Sapalemur grlseus in 1891, 

 of those of an extensive series of A^arious species of Jjem.ur, Galago, Chirogale, Lor'n^, 

 Xyclicehus, and Ferodlct'icns in 1895, and those of Mapalemnr simns and another 

 ILapalemur grlseus this year (1901) §. 



In 1895 the first of Theophile Chiidzinski's extraordinary memoirs 1| made its appear- 

 ance. It is a most peculiar document. The Avriter discusses the brains of Lemur, 

 Indris, and what he calls Loris gracilis. The data for the first two are apparently 

 borrowed from riowei-'s and Milne-Edwards's memoirs^; and the third — the only one 

 wliich the author himself describes — certainly belongs not to Loris gracilis, but to 

 ygclicehus tardigrudus. This error is the more singular because the author prefaces his 

 description with the remark that " it is easy, with a little practice, to recognize without 

 any difficulty the Order, Family, Genus, and often even the Species, to Avhich a particular 

 brain belongs " (p. 435). His second memoir, which deals with the brain of Chiromijs, 

 is so vaguely written and so poorly illustrated as to be almost valueless. 



In the same year (1896) Theodor Zielien gave an account of the cerebral hemispheres 

 of a large number of Lemurs, the nucleus of Avhich consists of the collection in the 

 Pioyal College of Surgeons **. 



In 1889 riatau and Jacobsohn gave a detailed account f f of the whole brain of a Lemur 

 macaco [or " macao,'' as they spell it throughout their book], and of a second bi-ain
