Or Hair Maniputations.—Those who are desirous of making manipulation of hair, 
(or, indeed, of any thing else,) without the microscope, but under a moderate magnifying 
power, should provide themselves with a pair of microscopic spectacles, the bridge of the 
frame of which, resting on the nose, while the lenses are at the proper focal distance from 
the eye; leave both hands of the manipulator at liberty, instead of obliging him to hold 
the magnifier in one hand and to work with the other only, in the usual manner. These 
spectacles are as simple in their construction as they are useful in practice. The magni- 
fying glass has a hinge, and opens inwards from the spectacle glass, so that it can, at 
pleasure, in a moment, be either placed or removed. By this arrangement you may use 
these spectacles as a microscope of moderate power, or as a common pair of spectacles.
