and handles, or otherwise, as above described. The ends of the axle-wheel work within the sides of the handles in two beds or sockets, the handles at their slower extremities or ends are made fast to the double share, breast, and body, or to either of them. The coulter Lemake of the same form as before described in my single plough, and fix it over the centre line or the double breast and expanding wings, and dropping it into a groove in the instep of the double share, is there made fast.

My improvements on double furrow ploughs are constructed upon the same principle as to the ridge, arch, or bridge; the wheels, rollers, and sledges, and also the centre or knife; as each centre and body has a wheel, roller, or sledge, affixed to it, as before explained and described in my single ploughs.

My improvements on ploughs to be worked by men (without horses), I construct upon the same principle as before described. My improvements consist also in a double-ended plough (worked by machines of my invention and construction); the body part of my double-ended plough is formed in like manner of those already described, with a ridge, arch, or bridge from the top of the body and breast, leaving a circular part of the wheel or roller to act and work in; but sometimes used without chaps for a beam, as is the case in the other ploughs, instead of which the draft is taken from the iron hooks at the top of each extremity of the ridge, arch, or bridge, from either side and from each end of the axle, as it works from furrow to furrow. The one point and share not in use is raised clear of the land by the points not heing fixed to the breast in a straight line, but forming a curve or partial angle at the bottom of each. These my improvements in the form, principle, and construction of ploughs, by the introduction and use of wheels,

rollers, and sledges, affixed to the centre and body of my ploughs, and the form and fixing of my coulter, are alike applied by me to all and every description of ploughs used in agriculture or otherwise. 10. 276 120 16 kad edIn witness whereof, &c.

To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said George Wyke do hereby declare that the nature of our said invention, and the manner in which the same is to be performed, are particularly described and ascertained by the annexed drawing, and the description thereof, at the foot of the same. A A, (Plate V.) shews a wheel, with its axle on one side of the centre, which may be placed at any distance from its centre, according to the length of stroke required for the piston to be composed of wood or metal. BBBB, smaller wheels, as antifriction rollers for A A to work against in bringing up or pushing down the piston. CC, piston!CC, shews a fly-wheel, which may or may not be applied for working the pump.

To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said William Finch do hereby declare that my said invention of an improvement in bridles for horses, which I call a philanthropic bridle, was never before made to the best of my knowledge and belief; the principle on which my invention was founded is as follows, and, as is more fully shewn by the drawings hereto annexed; (Plate IV.): In the place of a snaffle bridle bit, or any other bit or bradoon now in use, or in addition to such bit or bits now in use, I make use of a bit made tube fashion, thereby to admit, by means of side tubes connected therewith, as hereafter explained, the supplying, feeding, or nourishing the horse with water or any other liquor during his labour, either as a saddle-horse or carriage-horse, or any draught-horse whatever; the said bit so fashioned may be made of any outward form, and of any metal as has been the custom of the trade to make use of; the bit made of whatever outward form, or whatever substance, the same being made in a hollow form, or in a tube fashion, is the invention I lay claim to. The tube or tubes for containing the water or other liquor, are connected to the bit by soldering, by screw, or in any other way to the bit, so that when joined together the same are as one water-tight tube on each side of the horse's neck; when the same is for the use of coach or draught-horses, and for saddle-horses, the same, or such

like tubes to be made of tin or other metal with or with out a covering of leather or other coating, and may be supported by neck or head straps or collars as may be best approved; the length and size in diameter of the tubes may be of various dimensions, according to the size of the horse, or as best approved by the owner, to regulate the quantity of water or other liquor to drop into the horse's mouth, according to the number of miles the horse travels for a stage; for bits made without a joint in the mouth-piece one drop-hole only is necessary, and for bits with a joint in the mouth-piece two drop-holes, as near to the centre as can be for the purpose of cleansing. the apparatus; the bits, either with or without a joint, are in parts screwed, and to fill the tubes the caps on the tops of each are made to screw off. The terret on the collar to carry the tubes is so contrived with rollers as to allow for the to and fro motion, or side motion of the horse's head, and may be made of any metal, and with or without ornaments, and a hollow upright screw-pin is fixed on the top of a forewall of a carriage or draughthorse collar, to raise or regulate the height of the tubes, to make a proper fall to the horse's mouth as it may be required, agreeable to the height each horse may carry his head; and for a saddle-horse, the tubes to be raised by a neck-collar which lays across the neck of the horse, as is shewn by the drawings. In the lower end of the tubes is a sponge placed, which acts as a regulator, to ensure the constant dropping of the liquor, be the motion of the horse of any speed, slow or quick; there is also a check-piece or stop-valve in the middle of the tube, to ease the weight of the liquor on the tube, being filled at starting. The bridle is well adapted for the use of military in either saddle or artillery horses.

In witness whereof, &c.

Mr. John Fitchett, called in; and examined.

OU are secretary to the Runcorn bridge committee? Yes, and solicitor.

Can you communicate to the Commissioners any thing. concerning an experiment that was made at Liverpool, for the purpose of trying the strength of an extended rod of iron-I will state to the Commissioners what I know upon the subject:. I did not myself personally attend the trial of that experiment, having more particularly confined my attention to my own professional department, but in the course of that, having been engaged in the business from the commencement, I am acquainted with the proceedings of the Runcorn bridge committee, from the possession of the book; I have it not here; it is at my residence. I had only last night notice of this meeting, or I would have referred to the results of that experiment. Mr. Telford, in his report to the Runcorn bridge committee, after he had been selected to be the engineer employed for them, stated, that he had made upwards of two hundred experiments upon malleable iron of different lengths, varying from 31 to 900 feet; the plan delivered to the Runcorn bridge committee at first by Mr. Telford, was to be upon a span of 1,000 feet; the gentlemen of the Runcorn bridge committee con
