TitlePerkin, Arthur George: certificate of election to the Royal Society
CitationResearch Chemist in the Clothworker's Dyeing School, Yorkshire College, Leeds. Distinguished for his researches in Organic Chemistry, and especially in the section of this subject which comprises vegetable colouring matters. The results of these researches are published in upwards of 60 papers in the 'Journal of the Chemical Society.' Partly in conjunction with the late Prof J J Hummel he investigated Chay Root, Rubia Sikkimensis, and other similar plants, and succeeded in isolating and clearly proving the constitution of the Anthracene derivatives which they contain. His researches on Mang-kondu, Ventilago madraspatana , and many other plants largely used in India, Java, and elsewhere, on account of their valuable dyeing properties, have not only made us acquainted with the dyeing principles contained in these plants, but their chemical investigation has, in nearly all cases, led to a clear conception of their constitution. During the course of his researches on Luteolin, Morin, Apinin, Quercitin, and other Flavone compounds, he discovered and investigated curious compounds which such dyestuffs forms with acids. This work has afforded a valuable means of determining the molecular weight of such substances. In another paper he has described a new behaviour of colouring matters, which consists in their forming crystalline potassium salts when treated with potassium acetate. As only colouring matters which contain two hydroxyls relatively in the other position show this behaviour, the test affords further means of determining constitution. His researches include the investigation of the valuable compounds which colouring matters and other substances form with Diazobenzine chloride and the careful examination of the Glucosides, Tannins, Catechus, and similar compounds closely alied to the natural colouring matters. He has also published important investigations on Resorcylic Acid and its derivatives, on Haematein and Brazilein, on Kamala, Purpurogallin, etc, etc.
