"Epsom salts was very little used when I was an apprentice ; we used to purchase from 20 to 40 pounds of Glauber at a time, at 2J4 cents per pound, while we would only buy a single keg of Epsom, holding about 25 pounds, at 15 cents. The first really nice Epsom salts I recollect having in our store, was the year the College was organized ; John Farr, the noted chemist, was going to pay a visit to his 1 friends in London, and offered to make some pur- chases for us, and one of the articles in that first importation of our house was two casks, 1190 pounds of beautiful Epsom salts, at a cost here of 7 cents per pound, which was so much in demand by the retailers that we increased our orders, until the Baltimore manufacturers put a stop to our importations of the article. Super, carb. soda, which has been such a com- mon and universally used article of later years, was hardly ever seen when I was learning the business; I think the first we had in our store was purchased from Farr and Kunzi at $1.25 per pound, in 1821, when we paid them the same price for tartaric acid.
