| Title | Unpublished paper, 'Experiments made on a piece of peña silver, as to its capability of holding water; saved from the Lady Charlotte, wrecked on the Coast of Ireland in December 1838' by William Debonnaire Haggard |
| Creator | Haggard; William Debonnaire (fl 1839) |
| Date | January 1839 |
| Description | Haggard describes peña silver, or 'plata peña', which is silver collected by quicksilver after the ore is pounded; it is then placed in a mould, and by great force the quicksilver is squeezed out, forming a mass resembling dry mortar of great porosity. He measures the weight of the peña silver as it dries.
