These pills are probably taken in larger numbers than any other pills sold in Great Britain. If in proper condition they present iron in the form of the protocarbonate, either formed in the pills, or perhaps partially or entirely in the stomach. They are similar to Griffiths’ pills, which were the popular Mist. Ferri Co. in pilular form. Dr. J. Blaud, a French provincial practitioner, in an article published in the Revue Medicale, in 1831, entitled “Memoires sur les Maladies Chlorotiques,” gave the following formula:—
“Gummi Arabici, 5 grammes; solve calore baln. vapor in aquæ distillatæ, 30·5; syrupi simplicis 15 grammes; ferri sulfuric. sicci, 30; quibus caute mixtis adde kalii carbonici, 30; et inter agitatione ope spatula ferreæ in balneo vaporis evaporando ad massam pilularum redige; e qua forma pilulas 120; obducantur argento foliato.”
There has been much discussion concerning the best method of making these pills so as to keep them from oxidation. Honey was for a long time generally used as the excipient, but glycerin and sugar are generally preferred with gum acacia or tragacanth. Pilula Ferri, B.P., is a substitute for Blaud’s pills.
The Chelsea Pensioner.
An electuary for rheumatism bearing this title was evidently popular under the above name in the early part of the nineteenth century, but I have not been able to discover where or when or with whom it originated. The compilers of books of formulas naturally copy from each other, and consequently a legend once started is likely to become crystallised.
In The Chemist and Druggist, of June 13th, 20th, and 27th, 1896, an attempt was made to track this medicine to its origin, and a number of old formulas were sent in by correspondents. The statement is made in many books that the compound acquired its name from the circumstance that the recipe for it was given by a Chelsea Pensioner to Lord Amherst for gout and proved so successful that Lord Amherst gave him £300 and an annuity of £20. Sometimes this story associated Lord Anson with the pensioner and the amounts given in gratitude varied from £300 to 500 guineas, with an annuity sometimes of £20, sometimes of £30, and occasionally of £100. The then living descendants of Lords Amherst and Anson were written to by The Chemist and Druggist, but neither could give any information. It rather looks as if the fiction were concocted as an advertisement in the days when the electuary was a proprietary medicine, if it ever was.
The earliest formula traced in the correspondence referred to was given in Gray’s Supplement, 1821. This ran:—Pulv. gum. guaiaci, ʒi; pulv. rhei, ʒij; pulv. pot. bitart., 1 oz.; flor. sulph., 2 oz.; one nutmeg, and 1 lb. of honey. Of this, the dose was two tablespoonfuls night and morning. Sometimes pulv. pot. nit. is substituted for pulv. pot. bit.; probably a mistake of a copyist. In other formulas mustard appears instead of nutmeg; perhaps a similar slip for myristica. Treacle occasionally takes the place of honey, and the proportions of the ingredients vary considerably.
The Secretary of the Chelsea Hospital was good enough to take some trouble in reply to my inquiry to endeavour to trace this compound, but only negative results were attained. Dr. Thomas Ligertwood, the oldest living medical officer of the Royal Hospital, was appealed to, but he only knew of the remedy as “a very useful combination,” and had never heard the story of Lord Amherst’s purchase of the secret. He thought some information might be found in a work on the “Diseases and Infirmities of Old Age” by Dr. Daniel Maclachlan, a former Principal Medical Officer of Chelsea Hospital. That work (dated 1863) contains two allusions to the Chelsea Pensioner, but nothing about its history. Writing of Chronic Rheumatism the author says:—“ ... The more stimulating diaphoretics and diuretics prove serviceable. Among these the preparations of guaiacum deserve the confidence they have long enjoyed. The virtue of the powder (sic) known as the Chelsea Pensioner is chiefly due to the guaiacum and sulphur it contains.” In the section on gout he writes:—“The once famous Portland Powder has for long been abandoned, as has also the almost equally noted Chelsea Pensioner gout powder. One formula for the latter consisted of rhubarb, sulphur, nitre, and gum guaiacum, in equal parts. Fifteen or twenty grains of the powder were taken morning and evening in treacle. Another was powdered bark, ginger, guaiacum, aa ʒi, cream of tartar 1 oz., flowers of sulphur ½ oz., to be made into an electuary with simple syrup. One teaspoonful to be taken three times a day. This is certainly not a bad combination though a nauseous one.”
The following formula is given in the “Pharmacopœia Batava recusa cum notis et additamentis Medico-Pharmaceuticis,” published by J. F. Niemann, in 1824:—Resin of guaiacum, rhubarb, aa ʒij; supertartrate of potash, 1 oz.; sublimed sulphur, 2 oz.; one nutmeg; despumated honey, 1 lb. It is evident that this “Anti-Rheumatismal Electuary,” as Niemann calls it, and the Chelsea Pensioner had a common origin, and as the formula is not to be found in Niemann’s previous edition, 1811, it would appear to have come into popularity between that date and 1824. So far it remains doubtful whether its composition is due to an English or a Dutch author.
