Letter from John Allan Broun, 9 Abercorn Place, London to Humphrey Lloyd Discussion on independent comparisons. Broun suggests which of Lloyd's observations should be omitted and any good comparisons that should be used. Broun discusses Lloyd's definitions of the word independent and clarifies his own meaning. Broun agrees that Lloyd's definition is better, and discusses the differences between the two. Broun points out other areas of disagreement with Lloyd, such as using temperature comparisons. Discussion on Lloyd's comparisons for 1841. 13 February 1878
