Abstract

Yours of Sept. 17th has just reached me. The formula for the chromic acid solution is as follows: Take five gallons of water, add slowly 15 lbs. of sulphuric acid (Don't overheat jar and break it). After the acid and water get cool, add 7 ½ lbs. chromic acid. Stir well and solution is ready for use. ### I was in Baltimore a few days ago, but sickness at the house prevented me from calling on you. ### Put the acid solution in the porous cups, and water in glass jar, the same as the Bunsen. You might add a tablespoonful of sulphuric acid to the water in each jar. Yours truly, W.S. Logue
