ME CHA NIVAL EXTRACTION OF CREAM.

Ihe separation of cioim from milk by allowing it to rise "and float on the top, while easy ;iinl convenient, is slow, uud attempts have boon. m<ide to employ nieulicinic.il means to do the work. For this purpose a machine liiis been brought out which operates on the principle of the ordinary rotary dryer. The apparatus consists essentially of a cncular tank a holder, supported by an upiight shaft. Surrounding the shaft is a tube or sleeve, -lightly larger in diameter, and outside < f this is a second sleeve, st. ll larger, thus giving- two pipes reaching into the tank. From the outer pipe extend smaller pipes, radiating in every direction and entering the lauk near the outer edge. Under the tank is another pipe, open at the lower end and communicating" with the tank above, and a pail, or other vessel, below. In operation the tank is filled with milk, and the shaft is turned by bteam or other power at a speed of j about 2000 revolutions a minute. This motion at once tends to separate the cream from the milk, or better, the milk from the cream, by centrifugal force. The milk is driven toward the outer edge of the tank, while the cream gathers in the centre. This separation takes place at once, and in a faw minutes the cream may be drawn out through the central pipe, and the milk, taken from near the edge of the tank, through the outer pipe. At the same time, new milk may be added to the tank through the supply pipe below, the centrifugal tendency of the milk in tue tank being sufficient to draw up new supplies from the pail or other vessel below. Thus the separation of the milk from the cream is continuous so long as the supply of fresh milk is maintained. The cream extracted by this machine is reported to be entirely free from milk or water, while the milk is completely relieved of all its cream, showing a perfect separation of the two. Appliances are provided for regulating the density of the cream and for carrying tho process to completion without waste of time or material. — Scrib/wr's Magazine.

The Mayor of Christchurch is henceforth, to wear a frold chaio as a badge of office. Every memW of the Borough Council presents a link, so that it will not bo defrayed out of the rates. Alice Lewis, 54, was, at the Durham Quarter Sessions, committed to ten years' penal servitude on the charge of stealing a chair, value Gel. The prisoner had been previously convicted. The Count de Grasse was once wounded iv the knee with a musket ball. The doctors cut and hacked and made mauv incisions, when, getting out of all patience, the count asked why they cut him up so much. "We are seeking," said the surgeon, "for the ball."
