Midge it is quite different, for 
if the centre of this illustration 
be looked at, three eyes are 
seen edgeways, and it is quite 
evident they stand out—like 
a watch-glass from its case— 
from the surrounding tissues in 
a manner at once very striking. 
Nothing is known as to the use 
of this arrangement, and some 
have thought that it is an effect 
produced by the shrinking of 
the fluids of the eye after death, 
which makes the actual lens, so

would not account for the amount of protrusion, and may therefore be regarded as insufficient to 
explain so extraordinary a construction. In the same illustration attention is called to the tessellated 
membrane supporting these eyes, which is very beautifully executed ; it seems very curious such 
beautiful workmanship should be for ever hidden from our gaze save with the use of the microscope. 
AN EOCENE MONSTER 
A RHINOCEROS with the legs of an elephant is about as near as one could go in a popular brief 
definition of what the Tinoceras was. In the British (Natural History) Museum may be seen a cast 
of the skeleton which Professor 
Marsh discovered in Wyoming. 
This skeleton we reproduce, 
together with an attempt to 
clothe it with flesh and hide, 
and give a reasonable idea of 
its living appearance, based 
upon the clues which are fur- 
nished by the bony structure. 
The general resemblance is to 
a rhinoceros, but the legs are 
quite of the elephantine type, 
and the shape and positions of 
the toes suggest that the feet 
were provided with thick pads. 
It was about twelve feet in 
length, without including the
