Crinnis, and other mines near St. Austell, in large iridesoent crystals (Figs. 33, 35, 38, 39, 40, 41); BotaUack; Levant; Cook-s Kitchen, Tincroft, Condurrow, Tresavean, Carharrack, South Huel Basset, and other mines in the neighbourhood of Camborne and Redruth, formerly; Trevaunauce, St. Agnes; Huel Prosper; Herodsfoot; Trevascus, Trenance; Old Treburgett, St. Teath (Polytelite), Britannia and Prince Regent, North Molton; Beeralstone; Combemartin; Tavistock, &c.; also Scotland, France, Spain, Italy, Germany, Hungary, Mexico, &c. Obs. The largest crystals have mostly occurred at Crinnis and other mines near St. Austell. Fahlerz may be distinguished from magnetite and hematite by inferior hardness; from mispickel by its darker colour; from chalcocite (copper glance) by superior hardness and brittleness. The crystals may be distinguished from all other similar minerals except Tennantite by their form. Tennantite is probably only an arsenical variety of fahlerz. Perhaps analysis a. is Tennantite. The Polytelite from Old Treburgett contains a considerable proportion of silver. False Topaz. See Quartz. Felspar. This term, which is commonly applied to a particular species (Orthoclase), is more properly a name for a group of nearly-related species, differing from each other, however, in chemical composition, crystalline form, and other characters. Dana says, "The felspar gr...

Of Cornish descent, he was born in London.
He died at his home, Crinnis House, near Street Austell, on 12 April 1916 and is buried in Campdowns cemetery, Charlestown. He was at various times the Secretary or President of the three learned societies of Cornwall – Royal Geological Society of Cornwall (President from 1903–1904, and 1911–1912), the Royal Cornwall Polytechnic Society and the Royal Institution of Cornwall. Collins was the founding Secretary of the Mineralogical Society of Great Britain and Ireland in 1876 and was involved in founding the Institution of Mining and Metallurgy, becoming its Vice-President in 1892.
He also lectured for, and was secretary of, The Miners Association.
Collins pioneered systematic exploration for china clay in the Street Austell area, and had a long association with the area, as well as introducing both the filter press and the monitor to the china clay industry. From 1881–1884 he was the chief chemist and metallurgist for Rio Tinto mines in Spain but left due to ill health, possibly malaria.
