Excerpt from The Surveyor's and Engineer's Companion: Being a Concise Treatise on Mathematical Instruments, Containing an Improved Method of Telescopic Measurements, Illustrated With Numerous Engravings

With high powers, the field of view is very limited - the glass has to be very close to the object, and there is great loss Of light.

The low powers are by far the most useful for ordinary Objects - the easiest to the eye - give more light, and take in more of the Object.

With a power of 500 times, only the one-hundredth of an inch can be seen at a time.

With a power of 40 or 50 times, the field is one-tenth or one-twelfth of an inch.

Only low power, say 40 to 100 times, can be used for opaque bodies - the lower the better.
