The Tourist portable  model microscope. c. 1883

Higley's Educational microscope with chain drive focus

This microscope, now for the first introduced by us, is made portable, to meet the want of a compact instrument for use at the seaside, etc. It folds into a space about 6 1/2x3 1/4x2 3/8 inches. It is of brass throughout, handsomely finished, has broad and firm tripod base, axis for inclination to any angle, plane and concave mirrors, with adjustments for obliquity. For illumination of opaque objects, the mirror bar may be removed and replaced in the reverse position, thus bringing mirrors above the stage. The instrument stands 12 inches high when draw-tube extended (as shown in illustration).Society-screw, carrying an adapter with an achromatic object-glass of 4/10 inch focus, dividing to 8/10, which gives powers ranging from 40 to 140 diameters.

3077 and 3079 have a good fine adjustment, moving the stage, as in our Holmes Class microscope

3077. Queen's Tourist with rack and pinion and fine adjustments with live-box and forceps,  in mahogany case... $22.00

3078. The same without fine adjustment....$20.00

3079. Queen's Tourist, with coarse adjustment by slip-tube and fine screw adjustment, with live-box and forceps, in case... $17.50

3080. The same, without fine adjustment...$15.00

C. Baker, London sold an identical microscope. It is therefore possible that Queen imported the microscope from Baker and retailed it under the name of his firm.
