There are several species of them; some 01 which build npon the surface of the ground, whilst others form their habitations on the stems or branches of trce, at a vast height.

The European species do not appear to live together in numbers, but are usually found alone. The most common of these is the Termes p ulsatorius, a diminutive, white insect, that, during the summer months, frequents houses, and is often found in old wainscots, where it causes dismay to the ignorant and superstitious, by a long-continued sound, ex actly resembling the ticking of a watch, which they consider a prognostic of death. It infests collections of dried plants, and is very iijuri ous to them. When viewed in a microscope, the eyes appear large, tuid are of a most beau Ii ml gold colour, divided into inn umcrttble

isuied lenses.
