    Class IV.] GELATINOUS TllODUCTS, ENGLAND—AWARDS AND NOTICES. 355 gether with other chemical products of animal bodies in No. 1153. The Jury regard the above-named exhibitors of gelatines and glues as worthy of Honourable Mention. MM. Reiss de Dreuze, of Meurthe, and M. Faussemagxe, of Lyons, merit notice for their excellent gelatines from bones and isinglass for the purpose of dressing various stuffs and cloths. No. 376. The Company of Bouxwiller (Bas-Rhin) exhibits gelatine in small plates, much esteemed for various preparations or dressings ; it is extracted from the bones from which the same Company obtains phosphorus and phosphates of lime. This Company, No. 1214, MM. Estivaxt Brothers, and No. 1272, Humbert and Co., who exhibit excellent specimens of glues, are severally, in the opinion of the Jury, deserving of Honourable Mention. England. The greater part of the gelatinous products exhibited by the English manufac- turers is prepared from isinglass, and chiefly apjflied to articles of food. The commercial qualities of isinglass are instructively shown in the collection exhibited under Nos. 117, 118, and 141. Some exhibitors, however, show excellent glues and gelatines obtained from various residues of animal bodies, and destined for manufacturing purposes. Mr. Muller (No. 125a) has exhibited a fine assortment of glues and gelatines, analogous to the products of M. Grenet; but a part of his fine gelatine in threads, for confectionary purposes, appears to have been obtained from isinglass. This is deserving of Honourable Mention. M. Dufaville (125) shows a beautiful sample of amber-coloured, transparent gelatine in shreds, called ‘ crystalline,’ from its glittering surface ; and also good filaments of isinglass for culinary purposes. Messrs. Watt and Son (No. 120) exhibit fine specimens of glue obtained from the refuse pieces of hides and skins. Mr. James Vickers* (No. 117) exhibits a rich variety of specimens of isinglass in the different raw states in which it is imported, and in all the states of its preparation for the various applications for which it is sold. The variety of colours of the different kinds and parts of isinglass are exemplified in elegant forms and arrangements of this material. Messrs. Dawson and MoRRis (No. 118), and Class III., No. 141, Mr. Glass, have exhibited good specimens of isinglass, dried, beaten into layers, and cut into threads, exhibiting care and skill in the latter kinds of preparation. The Jury desire to make Honourable Mention of each of the above exhibitors. The Jury also deem worthy of Honourable Men- tion the beautiful specimens of refined gelatine, exhibited by Messrs. Swinborne. The more opaque filamentary specimens resembling isinglass appear, from micro- scopic and chemical tests, to be refined gelatine, from which the shining surface has been removed by a process of damping. This is a good material for the purposes of the confectioner, but is not adapted for clarifying white wines and beers, like true isinglass.
