Report on a comparison of Mint avoirdupois with Mint and Exchequer troy weights

<134r>

The 29th. April 1724.

Hond. Sr.

This morning early I went up into ye Mint office of Receipt, & finding Mr. Fauqur. had up ye 1lwt averdupois, I was oblige to compare the 7lwt. averdupois wth an Exact ballance of Troy wts. The scales & one sett of the Troywts. have been lately adjusted, but the other sett of weight remaining uncorrected, & there appearing about 6gr. difference between those 2 setts of Troy weights, I therefore compard the 7lwt Averdupois wth. both the foremention'd Setts of Troy weights, & also wth. the Troy Standd weights in the Excheqr. & the Acct. stands thus.

lwt			lwt	oz.	dwt	gr
7.	averdupois	=	8.	6.	0.	18.	Troy at ye Tower — Corrected, &c
7.	Do....	=	8.	6.	1.	0.	Troy at ye Tower — Vncorrected.
7.	Do.....	=	8.	6.	2.	6.	Troy at ye Exchr — Standd.

Consequently

lwt			lwt	oz	dwt	gr
1—	averdupois	=	1.	2.	11.	13.	fere at ye Towr. Corrected.
1.	Do....	=	1.	2.	121.	13.$\frac{\mathrm{5}}{\mathrm{7}}$.	Troy at ye Towr. Vncorrectd.
1.	Do.....	=	1.	2.	11.	18.	Troy at the Excheqr.

I am Sr.

Your most obedt & most Humble Servt.
