Extract

The specimens which form the subject of the present notes were contained ill a collection of minerals formed by the late Mr. Alfred Fox, of Falmouth, and which was acquired by myself in 1909. According to an old label with them, they are described as 'Murio-carbonate of lead taken up the 4th March, 1846, flora the wreck of the fire-shlp Firebrand, which was burnt in Falmouth Harbour about the year 1780. They were found under the lead pump, most of which appeared to be melted and mixed with charcoal.'
