There is hardly any natural production which is not 

 capable of displaying wonders beneath the microscope ; 

 the mechanism of insect forms is perhaps the most stri- 

 king, as much of this is either indistinct or unapparent 

 to the naked eye. A solar microscope, which may be 

 purchased for five or six guineas, will magnify the wing 

 of a midge, which is about one tenth of an inch in 

 length, to the apparent size of five feet by three. 



The leaves of plants, very thin sections across the 

 grain of various sorts of wood, and single drops of clear 

 stagnant water, afford beautiful subjects for inspection. 



Figure 2 is the natural size of the proboscis, or that 

 apparatus of a tabanus with which it pierces the skin 

 of horses and oxen, and nourishes itself with their 

 blood. Figure 1 is the same magnified.
