    N° 13,285 L'SGCM A.D. 1904 Date of Application, 11th June, 1904 Complete Specification Left, 4th Mar,, 1905-Accepted, 20th Apr., 1905 PROVISIONAL SPECIFICATION. “ Manufacture of New Derivatives of Lecithins/9 I, Charles Denton Abel, of Birkbeck Bank Chambers, Southampton Build¬ ings, in the County of London, Consulting Engineer and Chartered Patent Agent, do hereby declare the nature of this invention (as communicated to me from abroad by Actien-Gesellschaft fur Anilin-Fabrikation, of Berlin, in the 5 Empire of Germany, Chemical Manufacturers) to be as follows;—• By the present invention, new halogen derivatives of lecithin may be obtained by treating lecithin, preferably in a chloroform solution, with bromine; the different commercial lecithins shew a different capacity for absorbing or being incorporated with bromine, so that the highest proportion of bromine absorbed 10 is about 50 per cent. These new derivatives are of great value for medicinal purposes because they offer the possibility of combining the effect of bromine as a tonic remedy with that of lecithin as a nutritive preparation. This is because, unlike lecithin itself, the bromine derivatives are not changed by the action of the digestive 15 organs, so that the bromine-lecithin itself is resorbed, and not as it would occur otherwise, the products formed by the change of lecithin. In order to produce these bromine derivatives, lecithin may be dissolved for instance in chloroform and treated with bromine, the mixture being preferably kept at ordinary temperatures by cooling; the proportion of bromine may be 20 varied according to the kind of the commercial lecithin used. For instance lecithin derived from the yolk of eggs absorbs bromine up to about 30 per cent. Within the limits of bromine which the lecithin under treatment can absorb, the proportion of bromine may be varied as desired in every case. Dated this 11th day June 1904.
