This is a small compound monocular with a four-sided stage. This, in turn, can be mounted on a tripod stand with a sub-stage mirror mounted to one leg. The “MURRAY & HEATH / LONDON” inscription refers to a firm that began in business in 1856, and that showed various instruments at the International Exhibition in London in 1862. An account published in 1866 stated that this instrument was known as a “Sea-Side Microscope.” It was, moreover, “provided with a triple separating English achromatic, but being furnished with the Microscopic Society’s thread, may be used with any object glass.”
Several English opticians offered similar instruments.
