Chlorine.— James Watt was one of the first to introduce the use of chlorine as a bleaching agent.
Citric Acid.—Messrs. Sturge have over sixty years been manufacturing this pleasant and useful commodity at their works in Wheeley's Lane. The acid is extracted from the juice of the citron, the lime, and the lemon, fruit grown in Sicily and the West Indies. The Mountserrat Lime-Juice Cordial, lately brought into the market, is also made from these fruits. About 350 tons of the acid, which is used in some dying processes, &c., is sent out annually.
Coins, Tokens, and Medals.—Let other towns and cities claim pie- eminence for what they may, few will deny Birmingham's right to stand high in the list of money-making places. At what date it acquired its evil renown for the manufacture of base coin it would be hard to tell, but it must have been long prior to the Revolution of 1688, as in some verses printed in 1682, respecting the Shaftesbury medal, it is thus sneeringly alluded to:
'The wretch that stamped got immortal fame,
'Twas coined by stealth, like groats in Birminghame."
Smiles, in his lives of Boulton and Watt, referring to the middle of the last century, says, "One of the grimmest sights of those days were the skeletons of convicted coiners dangling from gibbets on Handsworth Heath." Coining was a capital offence for hundreds of years, but more poor wretches paid the penalty of their crimes in London in a single year than here in a century, wicked as the bad boys of Brummagem were. An immense trade was certainly done in the way of manufacturing "tokens," but comparatively few counterfeits of the legal currency were issued, except in cases where "a royal patent" had been granted for the purpose, as in the instance of the historical "Wood's half-pence," £100,000 worth (nominal) of which, it is said, were issued for circulation in Ireland. These were called in, as being too bad, even for Paddy's land, and probably it was some of these that the hawker, arrested here Oct. 31, 1733, offered to take in payment for his goods. He was released on consenting to the £7 worth he had received being cut by a brazier and sold as metal, and his advertisements (hand bills) burnt. These bad half pence weighed about 60 to the lb., 2s. 6d. worth (nominal) being somewhat less than 10d. in value. In the ten years prior to 1797 it has been estimated that 700 tons of copper were manufactured here into tokens, and the issue of the celebrated Soho pence, providing the nation with a sufficiency of legitimate copper coin, did not stay the work, the number of tokens in circulation in the early part of the present century being something wonderful, as many as 4,000 different varieties having been described by collectors, including all denominations, from the Bank of England's silver dollar to a country huckster's brass farthing. More than nine-tenths of these were made in Birmingham, and, of course, our tradesmen were not backward with their own specimens. The Overseers issued the well-known "Workhouse Penny," a copper threepenny piece, silver shillings and sixpences, paper notes for 2s. 6d, and leather bonds for 5s. With the exception of the penny these are all scarce now, particularly the 5s., 2s. 6d., and 6d., a specimen of the latter lately being sold at auction for 47s. In 1812 Sir Edward Thomason struck, for a Reading banker (Mr. J. B. Monk), 800 gold tokens of the nominal value of 40s. each; but this was just a step too far, and the Government forbade their use. In the same year he also manufactured two million penny tokens for our soldiers in Spain, which were not forbidden. The permitted manufacture of token money came to an end with the year 1817, an Act coming into force
