On the Occurrence of the Mineral Vivianite in the Ootteswolds, with 
remarks. By Freperick Sutras, L.L.D., F.G.S. 
I. Inrropvction.—Not one of the least of the functions of 
a Natural History Society is to make scientific capital from a 
diligent and business-like observation of nature. One of our 
Vice-Presidents, with a warm and earnest enthusiasm, has 
already attempted to give expression to the idea, by commencing 
to do something for the minerals of our county, by citing and 
systematically arranging the names, places and geological 
position of our more common forms, and so to enlist the 
attention of scientific observers as not only to obtain a trust- 
worthy census of the minerals of Gloucestershire, some of them 
already well known, but to bring to light and record the rarer 
and less obvious kinds ;—for there is good reason to suppose 
that many species one could name as almost certain to exist in 
given localities in the county have yet to be brought to book, 
and be catalogued. A case in point is that now laid before the 
members of the Cotteswold Club, as a small instalment towards 
Mr Lwvcy’s list, in his suggestive article, lately published in the 
** Proceedings” of the Cotteswold Natural History Field Club, 
(1881-1882,) page 30, entitled “On the Minerals of Gloucester- 
shire, with part of the adjacent Counties of Somerset and 
Worcestershire, compiled by Mr W.C. Lucy. Also a list of the 
Derived Rocks found in the Northern Drift Gravel over the 
same area. By Mr W. C. Lucy.” 
The mineral now exhibited, as an addition to the catalogue, 
is a specimen of Vivianite (Hydrated Phosphate of Iron,) of 
which a small portion was last year found by a young friend, 
Mr J. Marsprn, at Bowbridge, near Stroud, and was sent to 
me, with fossils and other natural history specimens, &c., to be 
named. Amongst these objects was the mineral Vivianite, 
occurring, in the non-crystallized or earthy state, as a bluish
