{{استشهاد بكتاب}}: صيانة الاستشهاد: مكان بدون ناشر (link)In 1758 the legislature turned attention to this subject; and after some investigations on the comparative lengths of the various standards, ordered a rod to be made of brass, about 38 or 39 inches long, and graduated from the Royal Society's yard : this was marked "Standard Yard, 1758," and was laid by in the care of the clerk of the House of Commons. For commercial purposes another bar was made, with the yard marked off from the same standard; but it had two upright fixed cheeks, placed exactly a yard asunder, between which any commercial yard measures might be placed, in order to have their accuracy tested : it was graduated into feet, one of the feet into inches, and one of the inches into ten parts. This standard was to be kept at the Exchequer. In 1760, a copy of Bird's standard, made two years before, was constructed.
We shall in the first place describe the state of the Standards recovered from the ruins of the House of Commons, as ascertained in our inspection of them made on 1st June, 1838, at the Journal Office… No. 1. A brass bar marked "Standard [G. II. crown emblem] Yard, 1758," which on examination was found to have its right hand stud perfect, with the point and line visible, but with its left hand stud completely melted out, a hole only remaining. The bar was somewhat bent, and discoloured in every part. No. 2. A brass bar with a projecting cock at each end, forming a bed for the trial of yard-measures; discoloured. No. 3. A brass bar marked "Standard [G. II. crown emblem] Yard, 1760," from which the left hand stud was completely melted out, and which in other respects was in the same condition as No. 1. No. 4. A yard-bed similar to No. 2; discoloured. … It appears from this list that the bar adopted in the Act 5th Geo. IV., cap. 74, sect. 1, for the legal standard of one yard, (No. 3 of the preceding list), is so far injured, that it is impossible to ascertain from it, with the most moderate accuracy, the statutable length of one yard. … We have therefore to report that it is absolutely necessary that steps be taken for the formation and legalizing of new Standards of Length and Weight.
