It is precisely for a similar reason that the combustion of an ordinary fire, being strictly a chemical change, is retarded whenever the sun's heating and luminous rays are most powerful, as during bright {440} sunshine, and that observe our fires to burn more briskly in summer than winter; in fact, that apparently "the sun's rays put out the fire." A. W. W. Univ. Coll., London. _Spontaneous Combustion_ (Vol. vii., p. 286.).--A most interesting discussion of this question is to be found in Liebig's _Familiar Letters upon Chemistry_. That chemist proves conclusively:--1. That of the cases adduced none is well authenticated, while in most it is admitted that the victims were drunkards, and that generally a candle or lamp was in the room, and after the alleged combustion was found turned over. 2. That spontaneous combustion is absolutely impossible, the human frame containing 75 or 80 per cent. of water; and since flesh, when saturated with alcohol, is not consumed upon the application of a light, the alcohol burning off first, the causes assigned to account for the spontaneous ignition are _à priori_ extremely improbable. A. W. WILLS. Univ. Coll., London. _Ecclesia Anglicana_ (Vol. vii., p. 12.).--This has always been the appellation of the Church of England, just as much before the Reformation as after. I copy for G. R. M. one rather forcible sentence from the articles of a provincial synod, holden A.D. 1257: "Et super istis articulis prænotatis fecit Bonifacius, Cant. Arch. suorum suffraganeorum sibi subditorum universorum, prælatorum pariter et cleri procuratorum, convocationem isto anno apud Londonias semel et secundo, propter gravamina et oppressiones, de die in diem per summum pontificem et D. Henricum Regem _Ecclesiæ Anglicanæ_ irrogatas."--Wilkin's _Concilia Mag. Brit. et Hib._, vol. i. p. 726. For other examples of the ante-reformational use of _Ecclesia Anglicana_, I can give him so large a reference as to Wilkins' book, _passim_; to the Writs for Parliament and Mandates for Convocation contained in the Appendix to Wake's _State of the Church and Clergy_; and to the extracts from _The Annals of Waverley_, and other old chronicles, quoted in Hody's _History of English Councils and Convocations_.
