The Presidential Address. 17 a character of the species everywhere". Neither the Elm nor the Beech is known in submerged forests, or in pre-historic works in wood. 16 DeCandolle suggests17 that the Latin name Tilia for the Lime is derived from the Celtic, and, since I doubt whether the Neolithic Mongols, the Finns of the Bronze Age, or the Celts are likely to have introduced exotic trees, this would make the Small-leaved Linden indigenous.18 The Romans in all probability introduced the cultivated Cherry, the English name of which is but a corruption from the Latin; 19 but it is none the less probable that one or more of the wild species may have been indigenous. The argument as to the Beech is similar to that with reference to the Lime. The tree has every appearance of being as wild as the Oak or the Hazel; its Latin name Fagus may very probably be of Celtic origin,20 Caesar's assertion that it does not grow in England21 may refer to the Chestnut, or may be otherwise explained. Our Secretary proposes to undertake the microscopical examination of the charcoal found in the pre-Roman camp at Loughton, a research of a difficulty only surpassed by its interest; for no doubt the wood of Beech and of Hornbeam will prove very similar when charred.

I certainly think the Professor under-estimates the antiquity of the Elm in saying that it can only "be traced back three centuries." 17 'Geographie Botanique,' p. 659.' 18 The Kentish name "Lyndhurst" is at least as old as the tenth century.—Pearson, 'Historical Maps,' p. 54. 19 "Cerasus, ciris beam, cherry."—Professor J.
