§ 1362. Designation of the Gyri. — TJie Sigmoid Gyrus. — This 

 name has been used, especially by English writers, to designate 

 the approximately s-shaped fold which curves about the lateral end 

 of the cruciate fissure (PL I, Fig. 1). Its surface includes several 

 quite constant and well-marked " motor areas " (Ferrier, A, Fig. 32 ; 

 Dalton, A, Fig. 113, 114). 



§ 1363. TJie External or Arched Gyri. — The four arched gyri which are so regularly 

 arranged in the fox and wolf were enumerated hy Leuret (Leuret et Qratiolet, A, I, 374 ; 

 Atlas, 9), beginning with that which immediately borders the Sylvian fissure, and ending 

 with that which forms the margin of the hemisphere. 



Since the fissure is constant and the margin variable, this would seem to be a natural 

 arrangement, and it has been adopted by Huguenin and some others. As appears, how- 

 ever, from the accompanying Table, several writers have modified it or reversed the order 

 altogether. Such transpositions are troublesome enough for skilled anatomists, and can 

 hardly fail to perplex the beginner.
