Measurements. 
The metrical system is now so generally in use for scientific purposes that I have 
adopted it for all the measurements of the magnified figures, and they are accordingly 
given in millimetres or tenths of a millimetre. The figures are nearly all enlarged by 
25 or 50 diameters, and scales are appended to all the plates.
