WALTER, John, M.P., eldest son of the late Mr. John Walter, of Bearwood, Berks, some time mem- ber for that county, born in London, in 1818, was educated at Eton, gra- duated in honours at Exeter Col- lege, Oxford, took his M.A. degree in 1843, and waa called to the bar at Lincoln's Inn in 1847.

WANKLYN, James Alfbbd, M.R.C.S., chemist; for some time lecturer on Chemistry and Physics at St. George's Hospital, at present public analyst for the county of Bucks, and the towns of Bucking- ham, High Wycombe, Peterbo- rough, and Shrewsbury (formerly Professor of Chemistry at the London Institution), was born in 1834 ; studied at Heidelberg under Bunsen, and, in 1858, prepared Propionic acid by the action of Carbonic acid on Sodium-Ethyl, being the first example of the arti- ficial production of an organic sub- stance directly from Carbonic acid. In 1861, in conjunction with Dr. Lyon Playfair, he communicated to the Royai Society of Edinburgh a paj>er " On a mode of taking the density of vapours of volatile liquids at temi)eratures below the boiling point." Subsequently he pursued conjointly with Dr. Emil Erlen- meyer a series of researches which, besides settling the formula of Mannite and uie relation of the sugar group to the alcoholic series, afforded one of the earliest and most complete studies of isomerism among the alcohols. In 1867, he prepared Propione, by the action of I Carbonic acid on Sodium-Ethyl, and, together with the late Mr. E., T. Chapman and Mr. Miles H. Smith, invented the well-known Ammonia process of Water Analysis. Some years later, conjointly with Mr. W. J. Cooper, he brought out the moist combustion process.
