COLORIMETER, Kuttner's Micro, for directly estimating haemoglobin and sugar in the blood; 

 uric acid, creatine, and creatinine in blood and urine; and for determining the renal function 

 according to the method of Rowntree and Gerahty. The instrument consists of a closed upright 

 box 2.5x2.5x8.5 cm, with openings for the graduated and the standard color tubes. The tubes 

 are viewed through a window in the front provided with a Helmholtz double plate, which shows 

 the colors in a continuous band, rendering the comparison very exact. A sliding door forms 

 the front of the box and affords protection to the prism. The size of the outfit enables it to 

 be carried in the pocket. Complete with housing of hard rubber with Helmholtz double prism 

 and sliding door; one each pipettes 25 cmm, 0.1 cc, 0.2 cc, and 2 cc; two graduated 10 cc test 

 tubes; one transfer pipette; graduated solution tube holding 140 cmm; and pocket carrying 

 case with sufficient space for several standard color tubes. (See Journal of the American 

 Medical Association July 17, 1915, pages 245 and 246; and April 29, 1916, pages 1370-1373) 18.00
