Revelations, 8th edition, 1901
One of the finest examples of this class of microscope at present brought within the reach of the average student’s means is that known as the ‘Edinburgh Student’s Microscope “ H,”’ by the firm of Watson and Sons. It is the most complete of a series of similar stands varying in cost and completeness. It is illustrated in fig. 173, where it will be seen that it has the first prime requisite, a rigid foundation combined with lightness—a tripod having at spread of 7 inches—and it is also possessed of at well-constructed mechanical stage which is built with the instrument, an advantage over the best attachable stage.
It is essentially a student as microscope, and although of so low a price is not only a specimen of the best workmanship, but is also extremely complete and represents an advanced type of construction capable of doing all ordinary and much experimental work .
