Bullock’s blood, dried by exposure in thin layers to a current of air, at a heat under 125°, and then reduced to powder, is exported in large quantities to the colonies, where it is used, as a ‘clarifier,’ in the sugar-works. Dried at a temperature ranging between 212° to 220°, then coarsely powdered, and the dusty portion sifted off, it is much used by fraudulent dealers to adulterate grain-musk.

Bloom of Almonds (ah′-mŭndz). Syn. Al′mond-bloom. Prop.
