Parts 1 & 2 were devoted to vision in Hyriopoda [cf. Zool. Rec. xxiv, 
Myr. p. 2] and Arachnida [cf. Zool. Rec. xxiv, Arachn. p. 1]. The per- 
ception of an object at a greater distance than £ to 2 centimetres — that 
is, about f to } of an inch— is very indistinct. [Cf. Tiebe (885).]

The compound eye, he concludes, does not give a definite perception 
of form, and is inferior, from the functional point of view, to that of 
Vertebrata. Perception of movement exists ; and, by the aid of a vivid 
sensibility to lights and shades, the Insect may be able to direct its 
movements. Noticed in J. R. Mier. Soc. 1889, p. 202.
