Very scarce. A handbook of English minerals with localities, chemical formulae, etc. It is based upon the large collection of English minerals brought together by Henry Ludlam [see note below], who bequeathed the collection to the Museum of Practical Geology in London and subsequently incorporated into the British Museum in 1997. The introduction gives an account of the musum.

Henry Ludlam. (Born: 14 October 1824; Died: London, England, 23 June 1880) English mineral collector. The youngest of a large family Ludlam studied architecture, but became instead a land surveyor, and subsequently a hosier. However the passion of his life was mineralogy and he amassed one of the finest private collections ever assembled in England, incorporating those made by Charles Hampden Turner which in turn contained those of Jacob Forster, Henry Heuland and William Nevill, which included that of diplomat William Garrow Lettsom. A wealthy man, Ludlam made extravagant purchases at mineral auctions and was a good customer of the countries mineral dealers. He died unmarried, bequeathing his large mineral collection to the Museum of Practical Geology, London, which has subsequently been incorporated into the Natural History Museum, London. He was a Fellow of the Geological Society and a member of the Mineralogical Society. The mineral "Ludlamite" was named in his honor by Richard Talling in 1876.
