Dated by the relationship to the letter to S. P. Woodward, [after 4 June 1856]. This note supplements the answers given by Woodward on the manuscript of the letter to S. P. Woodward, [after 4 June 1856] (see CD’s annotations).
The page references are to Woodward 1851–6, where most of the species noted are referred to. The general argument in Woodward 1851–6, 3: 398–9, also alluded to on p. 358, was that the Canadian lakes contain a few freshwater molluscs identical, or nearly identical, to European species. Woodward proposed that these species ‘strengthen the evidence … of a land-way across the north Atlantic having remained till after the epoch of the existing animals and plants.’ (p. 398).
The number of CD’s portfolio of notes dealing mainly with palaeontology and extinction.
