Geometric Tripod Stands. 



These stands, designed by Mr. C. V. Boys, F.R.S., are especially adapted for supporting pieces of apparatus, 

 such as galvanometers, lamps, etc. By their means a stand of any desired height may be made, each tripod 

 making geometric contact with the one immediately below it. A triangular groovS is formed on the upper 

 surface of the tripods into which the levelling screws of an instrument may be placed. The stands are supplied 

 in two sizes :
