NATURAL HISTORY 
MOUSE. 
Mice are of various colours, but mostly 
ash-coloured. In Savoy, and some parts of 
France, there are white Mice. They also 
differ in size. Their hearts are very large; 
and their liver and lights, according to some 
writers, increase in the winter, the fibres in 
them increasing and decreasing with the 
moon ; for every day of the moon’s age, there 
is a fibre increased in their liver, winch gave 
occasion to the observation : the moon feeds 
oysters, fills hedgehogs, and increases the 
fibres in Mice. In Africa, there are Mice 
which afford a musky scent, but have no bags 
like the civet cat; whence some think that 
the pleasant odours proceed from the skin. 
The Mouse never leaves its hiding place 
but to seek for food ; nor does it migrate un- 
less in case of necessity.
