Letter VII
To The Honourable Daines Barrington
Ringmer, near Lewes, Oct. 8, 1770.
Dear Sir,
I am glad to hear that Kuckalm is to furnish you with the birds of Jamaica; a sight of the hirundines of that hot and distant island would be great entertainment to me.
The Anni of Scopoli are now in my possession; and I have read the Annus Primus with satisfaction: for though some parts of this work are exceptionable, and he may advance some mistaken observations; yet the ornithology of so distant a country as Carniola is very curious. Men that undertake only one district are much more likely to advance natural knowledge than those that grasp at more than they can possibly be acquainted with: every kingdom, every province, should have its own monographer.
The reason perhaps why he mentions nothing of Ray’s Ornithology may be the extreme poverty and distance of his country, into which the works of our great naturalist may have never yet found their way. You have doubts, I know, whether this Ornithology is genuine, and really the work of Scopoli: as to myself, I think I discover strong tokens of authenticity; the style corresponds with that of his Entomology: and his characters of his Ordines and Genera are many of them new, expressive, and masterly. He has ventured to alter some of the Linnaean genera with sufficient show of reason.
It might perhaps be mere accident that you saw so many swifts and no swallows at Staines; because, in my long observations of those birds, I never could discover the least degree of rivalry or hostility between the species.
Ray remarks that birds of the gallinae order, as cocks and hens, partridges, and pheasants, etc., are pulveratrices, such as dust themselves, using that method of cleansing their feathers, and ridding themselves of their vermin. As far as I can observe, many birds that dust themselves never wash: and I once thought that those birds that wash themselves would never dust; but here I find myself mistaken; for common house-sparrows are great pulveratrices, being frequency seen grovelling and wallowing in dusty roads; and yet they are great washers. Does not the skylark dust?
Query.—Might not Mahomet and his followers take one method of purification from these pulveratrices? because I find from travellers of credit, that if a strict Mussulman is journeying in a sandy desert where no water is to be found, at stated hours he strips off his clothes, and most scrupulously rubs his body over with sand or dust.
