3080. COLORIMETER, Myers, a simple and inexpensive outfit for clinical purposes, consisting of a 

 box containing two tubes 26x1.2 cm graduated from 5 to 25 cc. Comparison of colors is made in 

 the nngraduated part through an opening 2.2x1 cm against a white glass background. The un- 

 known is diluted by the addition of water from the diluting pipette, until the colors match. 

 Calculations are very simple. Complete with housing, filling pipette with rubber bulb, holder 

 for pipette and two graduated tubes, in card-board box with directions for use. (See the Journal 

 of Laboratory and Clinical Medicine, VoL I, No. 10, for July 1916, page 760) 8.00
