country. The bowls w r eigh about sixty pounds, are twenty-one inches 

 high and twenty-two inches in diameter across the top. They have 

 received the name of the Union Bowls, and, being made of pressed 

 glass, can be afforded at a very moderate price. 



MACHINE FOR PREPARING AND PRESERVING BUTTER. 



THE St. Louis Republican states that Mr. E. H. Merryman has in- 

 vented and patented a machine by which he is enabled to restore to its 

 original sweetness the most rancid butter. It is also designed for pre- 

 paring and packing butter. It consists simply of two rollers in imme- 

 diate contact with each other, operated by a crank and spur-wheels. 

 They are placed in a trough and partially submerged in water. As 

 the butter passes between the wheels, every particle is brought into 

 immediate contact with the water, which washes away the butter- 

 milk as fast as it is pressed out. After this it is only necessary to 

 salt and pack it away in close vessels, and it will be preserved sweet 

 and pure for a long time. The machine occupies a space of about 

 four feet by two, and a single person can work with it seven hundred 

 and twenty pounds of butter per hour. Rancid butter put into it comes 

 out completely divested of all rancid taste or smell. 



CANDLE-MAKING APPARATUS. 



MR. A. L. BROWN of New Haven has invented an improved ap- 

 paratus for making mould-candles. The improvement consists in con- 

 structing the mould with a screw on the upper part, about two inches 

 from the end, for adjusting and securing it to the frame, and a shoulder 

 near the upper end, to support the tallow-table, and a hole to admit 

 the wire which supports the wick ; also in attaching all the wires to 

 a slide worked by a jointed wire-handle, and governed by a guard, so 

 that all the wicks may be evened by one motion of the hand, and then 

 be all centred by another motion. There is also a smooth tallow- 

 table, level with the tops of the moulds, to allow the tallow to be 

 easily scraped off. Scientific American, Feb. 9. 



WEIGHING AND REGISTERING SCALE. 



THE Lafayette (Indiana) Journal describes a new " self- weighing 

 and moving-index discharging scale," for weighing grain, the inven- 

 tion of Mr. W. W. Bramble. It says : " The frame which supports 

 the scale-bearn also supports a permanent hopper, made like those in 

 common use, which receives the grain to be weighed. Suspended to 

 the scale-beam is a box, which incloses the revolving hoppers in which 

 the grain is weighed, and the machinery which controls the move- 

 ments of the scale. There are four revolving cylindrical hoppers in 

 this box, attached to a shaft, something similar to the boxes of an 

 overshot water-wheel. Connected with the journals of this shaft, on 

 each end, is a register, with a dial-plate or face similar to that of a 

 watch. The dial-plate on one end is divided into three registers.
