Castelle, of Paris, exhibited (No. 107) a still more varied assortment of the modifications of gelatine, amongst which were particularly deserving of notice the very large sheets of transparent gelatine, colourless, white, of various well-defined colours, and embossed or stamped with elegant patterns. Jacob Bell, Esq., M. P., in his lecture on pharmaceutical pro- cesses and products, gives a curious illustration of the extent to which tlie consumer is prejudiced by the obstacles which inter- vene between himself and producer:— An ingenious application of the science of chemistry consists in the manufacture of artificial essences of pears, pine-apples, and other fruits.
