PHILADELPHIA 
il— educational Dissecting microscope 
The demand for a dissecting stand embodying all the necessary conveniencies 
and at the same time of moderate cost, led to the construction of the Educational 
Stand, and the great popularity it has attained has justified improving it to meet 
still more the requirements of advanced methods. The base of the stand is of 
japanned metal and very heavy, insuring stability. All other parts are heavily 
nickeled, preventing erosion by reagents. The stage is of large size, and the 
opening is provided with a glass disc. 
The lenses are carried by a metal arm, movable above the stage, and are 
focussed by means of the knob shown at the side of the pillar, in the engraving, 
this method being entirely satisfactory for lenses of the powers used. We list the 
U stand with the Triplet, Coddington and Doublet Lenses, but would advise 
the purchase of the Triplets or Coddingtons wherever funds will permit, on account 
of their superior defining power. Each U microscope is furnished in a neat 
wooden case. 
Metal H and Rests are applicable to all the U stands, and are furnished at an 
extra cost.
