944 PROF. W. H. MILLER ON THE CONSTRUCTION OF THE NEW STANDARD POUND. 
1825j the Standard Brass Weight of One Pound Troy Weight made in the Year 1758, 
then in the Custody of the Clerk of the House of Commons, should be and the same 
was thereby declared to be the original and genuine Standard Measure of Weight, 
and that such Brass Weight should be the ‘ Imperial Standard Troy Pound,’ and 
should be and the same was declared to be the Unit or only Standard Measure of 
Weight from which all other Weights should be derived, computed, and ascertained, 
and that of the said Troy Pound should be an Ounce, and that ^ of such Ounce 
should be a Pennyweight, and that of such Pennyweight should be a Grain, so 
that 5760 such Grains should be a Troy Pound, and that 7000 such Grains should be 
and they were thereby declared to be a Pound Avoirdupois : And whereas by the said 
Act Provision was made for restoring the said Imperial Troy Pound, in case of Loss, 
Destruction, Defacement, or other Injury, by Reference to the Weight of a Cubic 
Inch of Water : And whereas the said Standard Pound Troy (was) destroyed in the 
Fire at the Houses of Parliament : And whereas by the Researches of Scientific Men 
Doubts were thrown on the Accuracy of the Methods provided by the said Act for 
the Restoration of the said Standard ; And whereas there exist Weights which had 
been accurately compared with the said Standard Pound Troy, which afforded suffi- 
cient Means for restoring such original Standard : And it having been deemed 
expedient that the Standard for Reference as a Measure of Weight should be a Pound 
Avoirdupois, there has been constructed a Pound Weight Avoirdupois equivalent to 
the Pound Avoirdupois of 7000 such Grains as are mentioned in the said recited Act, 
and Four accurate Copies of the said Pound Avoirdupois so constructed : And 
whereas the Standard Pound Avoirdupois so constructed as aforesaid, and the Copies 
thereof, are of Platinum, the Form being that of a Cylinder nearly 1’35 Inch in Height 
and 1'15 Inch in Diameter, with a Groove or Channel round it whose Middle is 
about 0 34 Inch below the Top of the Cylinder, for insertion of the Points of the 
Ivory Fork by which it is to be lifted; the Edges are carefully rounded off: And 
whereas the said Standard of Weight marked P.S. 1844, 1 lb. has been deposited in 
the Office of the Exchequer at PFestminster, and One of the said Copies of the 
Standard of Weight marked No. 1. P.C. 1844, 1 lb. has been deposited at the Royal 
Mint; and One other of the said Copies of the Standard of Weight marked No. 2. 
P.C. 1844, 1 lb. has been delivered to the Royal Society of London-, and One other 
of the said Copies of the Standard of Weight marked No. 3. P.C. 1844, 1 lb. has been 
deposited in the Royal Observatory of Greenwich ; and the other of the said Copies 
of the Standard of Weight marked No. 4. P.C. 1844, 1 lb. has been immured in the 
Cill of the Recess on the East Side of the lower Waiting Hall in the New Palace at 
Westminster \ And whereas it is expedient to legalize the Standards so constructed 
and to provide for the Preservation thereof: Be it therefore enacted. ..as follows: — 
I. So much of the said Act of the Fifth Year of King George the Fourth as relates 
to the Restoration of the Standard Troy Pound, in case of Loss, Destruction, Deface- 
ment, or other Injury, shall be repealed.
