lcservc a particular descript ion, many insects have three small, round, brilliant globuics on the crown of the head, called stemmala. The. eyes of most insects, instead of being single, arc composed of a prodigious number of little hemispheres, or round ptot uberances, placed with the utmost regularity and exactness, in lines Crossii)g each other like lattice svork this group is supposed to be a collection of eyes. What wonders does the microscope enable us to behold! My mother has shown me the figure of a candle, multiplied almost to infinity, on the surf=aces of one of these clusters of eyes the beams of light sl.iifting from eye to eye, ac cording as I moved. the candle. Whilst other creatures are obliged to turn their eyes towards the objects they wish to see, thecae have always some or other of their eyes so directed, as to take in the surrounding objects on whichever side they present themselves, Each of these in d ivid ual eyes has a minute, transparent lens and

pupil, through which things appear inverted, as in the human eye, and, when properly

placed, serves the office of a telescope, by

bringing (liStant objects to the sight. Mr.
Leuwmhos k, a celelebrated naturalist, looked
through the eye of an insect, by the assistance
