MINERAL WATERS AND MEDICINAL SPRINGS OF ESSEX. 193 39 pp., demy octavo (about). The author's name appears only at the end of the Preface (pp. 3-4), which is dated from "Hatton Garden, January 20, 1779," and is almost identical with that in the 3rd ed. The Dedication to Sir Hans Sloane (d. 1753) is omitted. This is another completely new edition, the book having been again reset throughout. There was a later edition in 1781. The John Ellison whose name appears as publisher was the agent for the sale of the water in London (see post, p. 222). 1781.—[ANDREE, John]—An Account of the Tilbury Water [&c., Fifth. edition, London, 1781]. We have seen no copy of this edition, but it is mentioned in the Dict. of Nat. Biogr. and by Mr. Dalton (see post, p. 194). 1783.—TRINDER, W. Martin, LL.B. (Oxford) and M.D. (Leyden).—An Enquiry, by Experiments, into the Properties and Effects of the Medicinal Waters in the County of Essex. . . . London : Printed and sold by J. F. and C. Rivington, in St. Paul's Church Yard ; Mr. Faulder, in Bond Street ; Mr. Frost, Chelmsford ; and Mr. Marshall, Grocer, at Romford, 1783. xvi + 56pp., demy octavo. The Dedication to Robert Edward, 9th Baron Petre of Writtle, is dated "Romford, January 1783." The Preface (pp. v-xiii) is unsigned. The author describes ten Essex Mineral Springs—namely, those at Tilbury Hall (pp. 1-8), Tilbury Rectory (pp. 9-12), Gidea Hall (pp. 13-19), Hornchurch Lane (pp. 20-23), "Forest" (i.e., Stapleford Abbots, pp. 24-28), South Weald (pp. 29-34), Upminster (pp. 35-40), Witham (pp. 41-46), Springfield (pp. 47-52), and "Felstead" (pp. 53-56). Of these, four (namely, those at Gidea Hall, Hornchurch, Stapleford Abbots, and Springfield) had not, we believe, been described previously. The Rev. Dr. Trinder (1747-1818) was a son of David Trinder, of Shadwell, Middlesex. He matriculated at Exeter College, Oxford, on 31 Oct. 1763, at the age of 16, and afterwards proceeded to Leyden, where he took his degree of M.D. He became B.C.L. of Oxford in 1770. He wrote and published several Sermons, An Essay on English Grammar (before 1783), and a work on the Oil and Air Bath (1812). He died at Rowley Lodge, near Barnet, on 18th Dec. 1818 (See Alumni Oxon., 1715-1886, iv, p. 1439 : 1888, and Gentl. Mag., lxxxviii., pt. ii, p. 574 : 1818). 1841.—PHILLLPS, Richard, F.R.S.—[A. Report on his Analysis of the Water of Hockley Spa. 1841.] A pamphlet. No copy seen by us, but mentioned by Granville (Spas, ii, p. 610). Mr. Phillips (1778-1851) was born in London, of Quaker parentage. He was an eminent chemist, as well as a voluminous writer and lecturer on chemical subjects. He analysed the waters of Bath in J806, of Cheltenham in 1818, of Weymouth in 1833 ; was elected F.R.S. in 1822 ; and was Pres. of the Chemical Society in 1849-50. 1841.—GRANVILLE, A. B., M.D., F.R.S.—The Spas of England. . . . London, 1841. Consists of three "parts" in two volumes, post octavo. The only Essex Spa noticed is that at Hockley (called "Southend"), which is described very fully (vol. ii., pp. 606-614). Dr. Granville (1783-1872) was born in Italy, of mixed English and Italian parentage. After serving as a surgeon in the English Navy, he settled in London, where he practised extensively and became a recognised authority on midwifery. He wrote voluminously on medical subjects, mineral waters, Italian political questions, and the Royal Society, of which he was a keen critic.
