Method for Concentrating Blood.

A cheap and rapid method for concentrating the enormous quantities of blood collecting in abattoirs has been invented recently. The blood is injected into an oven-shaped chamber, open at the top, and brought into contact with a current of hot air ascending from below. All the water is evaporated in this manner, and the blood powder is carried to the receiving chamber. The product thus obtained Is tasteless, and contains 78.4 per cent of digestible albumen.
