All bodies together, and each by itself, give off to the surrounding  
air an infinite number of images which are all-pervading and each  
complete, each conveying the nature, colour and form of the body  
which produces it.  
It can clearly be shown that all bodies are, by their images,  
all-pervading in the surrounding atmosphere, and each complete in  
itself as to substance form and colour; this is seen by the images  
of the various bodies which are reproduced in one single perforation  
through which they transmit the objects by lines which intersect and  
cause reversed pyramids, from the objects, so that they are upside  
down on the dark plane where they are first reflected. The reason of  
this is--  
[Footnote: The diagram intended to illustrate the statement (Pl. II  
No. i) occurs in the original between lines 3 and 4. The three  
circles must be understood to represent three luminous bodies which  
transmit their images through perforations in a wall into a dark  
chamber, according to a law which is more fully explained in 75?81.  
So far as concerns the present passage the diagram is only intended  
to explain that the images of the three bodies may be made to  
coalesce at any given spot. In the circles are written,  
giallo--yellow, biàcho--white, rosso--red.  
The text breaks off at line 8. The paragraph No.40 follows here in  
the original MS.]
