BENEDICT'S SOLUTION - QUALITATIVE: Cupric sulfate 17.3 g. , Sodium 

 citrate 173 g. , sodium carbonate 100 g. , water 1000 ml. Dissolve the 

 sodium citrate and carbonate in 800 ml. water (filter if necessary). 

 Dissolve the cupric sulfate in 100 ml. Add the cupric sulfate slowly to 

 the citrate -carbonate solution with constant stirring and dilute to 1 

 1 iter . 



BENEDICT'S QUANTITATIVE SUGAR REAGENT: Cupric sulfate 18 g. , sodium 

 carbonate (1/2 weight of anhydrous salt may be used) 200 g., sodium or 

 potassium citrate 200 g., potassium thiocyanate 125 g. , potassium ferro- 

 cyanide (5% solution) 5 ml., water to make up volume to 1000 ml. With 

 the aid of heat dissolve the carbonate, citrate, and thiocyanate in 

 enough water to make 800 ml., and filter if necessary. Dissolve the 

 cupric sulfate separately in 100 ml. and mix slowly with the other 

 solution. 25 ml. of the reagent are reduced by 50 mg. of glucose. 



BRODIE'S SOLUTION: Water 500 ml., sodium chloride 23 g., sodium 

 chlorate 5 g. , 1% (aq.) methylene blue 3 ml., thymol O.lg. 



CARBO-XYLOL: 1 part liquified phenol (see below), and 3 parts of 

 xylene. 



CARLSBAD SALTS, SYNTHETIC: (Sprudelsalz ) Sodium sulfate 11 g., 

 sodium bicarbonate 10 g. , sodium cliloride 9 g. , potassium nitrate 19 g. , 

 potassium sulfate 1 g. 



CEMENT: Beeswax 58%, rosin 29%, Venetian turpentine 13%. 



CHALKLEY'S MEDIUM: Water 1000 ml., sodium chloride 0.1 g., potassium 

 chloride 0.0004 g., calcium chloride 0.006 g. 



CHLORETONE: Chlorbutanol 0.6 g. soluble in 100 ml. water 20°C. 



CLARK'S FLUID: (for insect tissue culture) Water 200 ml., sodium 

 chloride 1.3 g. , potassium chloride 0.028 g., calcium chloride 0.024 g. , 

 sodium bicarbonate 0.02 g., monobasic sodium phosphate 0.002 g. 



CLEANING SOLUTION: Dissolve 60 - 65 g. , of sodium or potassium 

 bichromate by heating in 30 - 35 ml. of water. Cool and slowly add con- 

 centrated sulfuric acid to make a liter of solution. 



CLERICI'S SOLUTION: 10 ml. water, 50 g. thallium (ous) malonate, 50 g, 

 thallium (ous) formate, 0.1% sodium t auroglychocholate . Keep cool and 

 filter. Density about 4.
