LETTER VII.
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 a 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.
