    By Thomas Taylor, Esq. To Bichard Taylor, Esq. Dear Sir, CEVERAL statements having appeared in the continental ^ journals with regard to the composition of some new species of biliary and intestinal concretions, I have received permission from the Museum Committee of the Royal College of Surgeons to state, that in the second and third parts of the Catalogue of the Calculi and other Concretions, which will shortly be published, the following facts will be shown :— 1. That the lithofellinic acid calculus, described by Profes- sors Goebel and Wohler, Ann. der Pharm. for 1841, b. xxxix., and Gotting. Gelchr. Ana. for the same year, is not a new species of calculus, but is identical in composition with the calculus described and figured by Fourcrov and Vauquelin in the first volume of the Ann. du Museum National as i( re- sine ahimale bez'oardique.” Also that it is not a biliary calcu- lus, or in any way connected with the biliary secretion, as its name would iriiply, but that it is derived from the resinous juices contained in the plants, &c. on which the species of wild goat, termed by the Persians Pasen, browses. This view of the origin of these bodies is advocated by Kaempfer in his Amcenitates Exoticee,' and its correctness will be proved on chemical and other grounds. 2. That several intestinal concretions have been discovered consisting of the insoluble acid obtained by Braconnot from the infusion of gall-nuts, and termed by him ellagic acid. The constituent of these concretions has been described by John, C/iem. Sc/ir. 3. 38, under the name of Bezoarstoff. It forms also the ligniform matter of Berthollet, “ Holzartige Materie ancj I have also no doubt that it is the peculiar acid from the oriental bfezoar, described by M. Lippowitz in Simons’s Beitrage zur phys. et pathol. Chemie, b; i. p. 463, and termed by him bezoaric acid.

Guibourt, in the Journ. de Pharm. et de Chemie for February 1843. , -0 . ! , ; Biliary Calcidi.—In addition to the stearate of lime calcu- lus, already described in the Phil. Mag;*, I have to announce the existence of another species, which resembles in most of its chemical habitudes the colouring matter of the bile (Chole- * S. 3. vol xvii. p. 8.
