THE EYE IN EVOLUTION 



answering the needs of the animal which in most cases is of sluggish habit 

 with slow movements and a limited range of vision. In this view the two 

 tendencies appear to rim parallel rather than to be linearly derived. Which 

 theory is correct must still remain a matter for discussion. 



For the phylogeny of the pineal body, see the elaborate inonograph of Gladstone 

 and Wakeley (1940) ; its morphology and histology are well discussed in those of 

 Studnicka (1905), Tilney and Warren (1919) and Rio-Hortega (1932) ; its physiological 

 functions (as a gland of internal secretion) are fully noted by Kidd (1913), Schafer 

 (1926) and Bors and Ralston (1951) ; the vast clinical literature is found in Bailey 

 and Jelliffe (1911), Boehm (1920), Laignel-Lavastine (1921), Horrax and Bailey (1925) 

 and Calvet (1934) ; the veterinary literature in Santamarina and Venzke (1953).
