spaces from the centre of the plate, the tool seems to have been 

 used in one direction only, without moving the metal plate, the 

 apertures being all cut from the same side, and the cut surfaces 

 bevelled in the same direction. The metal of which it is composed 

 seems to be very pure and fine. One of the blades, however, has 

 become considerably corroded, the green carbonate of copper having 

 formed over a great part of its surface. 



The implement measures 3| inches in length, the handle being 

 2J inches long; each of the blades is 2§- inches in length, by fths 

 of an inch across the middle ; and the whole measures 3£ inches 

 across, from face to face of the rounded blades. The handle is 

 ith of an inch in thickness ; and the metal is gradually thinned 

 down from the centre, to a fine edge, on each side.

The shape and character of the instrument shows it to have 

 been evidently intended for some cutting purpose, and reminded 

 me at first of a saddler's or shoemaker's knife for cutting leather. 

 The extreme delicacy and thinness of blade, however, would make 

 it quite unfit for any such rough purpose. 



Irish Bronze Instrument. — In the Catalogue of the metallic 

 materials in the Museum of the Eoyal Irish Academy, under the 

 title of Toilet Articles, a figure is given of the largest of three 

 bronze implements, which appear to me to belong to at least the 

 same Class of instruments as this one, though certainly not to 

 exactly the same species or pattern. (See the annexed woodcut, 

 fig. 2, where this Irish bronze is drawn to a scale of one-half its
