soap is ordered. In the P.L., 1851, the oil of amber was omitted. It has been recommended for external application in rheumatism and paralysis.
It has been generally asserted that this preparation was devised by a pharmacist of Lille (some say of Amsterdam), of the name of Luce. It is also asserted that a Paris pharmacist named Dubalen originated it, and that he and his successor Juliot made it popular; that Luce of Lille imitated it, but that not being able to get it purely white added some copper and gave it a blue tint which came to be a mark of its genuineness. Among the names applied to it have been Aqua Luccana, Aqua Sancti Luciæ, Aqua Lucii, and Eau de Lusse.
Bromine.
Bromine, isolated by Balard in 1826, was named by the discoverer Muride, from Muria, brine. Its actual name was suggested by Gay Lussac from Bromos, a stench.
Schultzenberger relates, on the authority of Stas, that some years before the discovery of bromine by Balard, a bottle of nearly pure bromine was sent to Liebig by a German company of manufacturers of salt, with the request that he would examine it. Somewhat carelessly the great chemist tested the product and assumed that it was chloride of iodine. But he put away the bottle, probably with the intention of investigating it more closely when he had more leisure. When he heard of Balard's discovery he turned to this bottle and realised what he had missed. Schultzenberger says he kept it in a special cupboard labelled "Cupboard of Mistakes," and would sometimes show it to his friends
