Sends record of pigeon flight from London to Antwerp. [Lord W. Lennox, Merrie England (1857), p. 185.]
Extracts from MS of vol. 4 of HCW’s Cybele Britannica [1847–59] showing the diversity of views on species among botanists.
Calculations relating to bees’ cells.
Discusses the ranges and distribution of varieties relative to the type species.
Zebra-striped asses.
Markings of a Bengal jungle cock.
Refers to some of his own articles on birds in India.
Reports the arrival of the "glorious garrison of Lucknow". The "wonderful superiority of the European to the Asiatic" made the success of the insurrection inconceivable.
Has gone over to CD’s side on the fertilisation of clover in New Zealand by bees.
Bees’ cells. Observations on Osmia atricapilla.
Describes some species of fauna peculiar to Fernando Po. The ocean currents make it unlikely that animals have been floated to the little islands [off the west coast of Africa].
GRW’s observations of and ideas on bees’ and wasps’ cells.
Gives some observations on birds; has forwarded a box of specimens.
Believes that botanists tend to mark more varieties in large than in small genera, but notes that where many varieties of a species exist these varieties may well be passed over, whereas similar varieties of another species which are fewer in number may well be recorded.
Botanical practice can confuse CD’s compilations. Many small genera would have been species had the whole natural order [family] been known.
JDH’s low opinion of Buckle;
high opinion of Mrs Farrer.
Identifies an ant described by CD and discusses the predatory habits of Formica sanguinea.
Describes some wasps’ nests.
States his belief that there is a tendency to note varieties in the larger genera rather than in the very small ones.
Summary of JDH’s objections to CD’s survey of floras and conclusion that large genera vary more than small.
Continued objections to methods and conclusions of CD’s survey.
Discusses the ranges of species in large and small genera; difficulties involved in limiting the discussion to Britain.
List of close species taken from AG’s Manual of botany [1848].
Bees’ cells; GRW thinks hexagonal shape is accidental. Encloses notes on cells of Icaria.
[Six fragments, mainly diagrams.] The geometry of bees’ cells.
