Thediagram here given in the margin stands, in the original, betweenlines 3 and 4. OF THE ATMOSPHERE THAT INTERPOSES BETWEEN THE EYE AND VISIBLEOBJECTS. If the eye remains stationary the perspective terminates in thedistance in a point. A spot is most illuminated when a large number ofluminous rays fall upon it. The lights are of two kinds, one called original,the other borrowed. Those parts of a shadow will appear darkest which have darkerobjects opposite to them. A light object will look larger when it is seen against a backgrounddarker than itself.

And the larger the light object opposite, themore the shadow will be lightened. If the eye remains stationary the perspective terminates in thedistance in a point. This passage is so obscure that it would be rash tooffer an explanation. WHY A SHADOW WHICH IS LARGER THAN THE BODY CAUSING IT HASILL-DEFINED OUTLINES. )And the rest will be set forth in the Book on Painting. Thus itis with the sun by day, as well as the moon and the other eternallights by night. A light object will look larger when it is seen against a backgrounddarker than itself. OF THE RAYS WHICH CONVEY THROUGH THE AIR THE IMAGES OF OBJECTS. A shadow is always affected by the colour of the surface on which itis cast. Effects on cast shadows by the tone of the back ground.

An image produced in a mirror is affected by the colour of themirror. C the order ofthe original paging has been adhered to, and is shown inparenthesis. And they will appear less dark when theyface lighter objects. On indistinctness at great distances (232-234). Hence objects of this kind cannot throw any reflected lighton opposite objects. _The reciprocal effects of colours on objects placed opposite eachother (263-272). Propositions on perspective of disappearance from MS. Objects seen between light and shadow will show the most relief. The surface of any opaque body is affected by the colour ofsurrounding objects. Propositions on perspective of disappearance from MS. An image produced in a mirror is affected by the colour of themirror. A light object will look larger when it is seen against a backgrounddarker than itself. The lights are of two kinds, one called original,the other borrowed.
