^{page 55 note *} “Not taken daily.”

^{page 55 note †} Mirehouse is four miles NNW. from Keswick.

^{page 56 note *} The gauge at Seathwaite, I have been informed, was not examined daily, only on the days specified in the table. As observations were made on the 25th, 26th, and 27th, there can be no doubt respecting the correctness of the amount, 7·52 inches, during the twenty-four hours.

In the preceding table, the number of rainy days at Seathwaite is given as the same as at Keswick, where a strict account was kept. It is believed by those acquainted with the two localities, nine miles only apart, that when there is rain at Keswick there is a certainty of rain at Seathwaite.

^{page 63 note *} Sea-water which I have examined, taken from the neighbouring sea, I have found to contain, besides the ordinary ingredients of sea-water, lime in a notable quantity, some alumina and sulphuric acid, and traces of ammonia and phosphoric acid.

^{page 63 note †} I have been informed by a friend residing at Meltham Parsonage, and by another residing at Armitage Bridge, both places in the neighbourhood of Huddersfield, and about eighty miles from Scarborough, and about sixty from Liverpool, the nearest ports of the opposite coasts, that after the great storm of January 1, 1839, salt was observed deposited on the leaves of the trees at both places;—they were about four miles apart.

^{page 64 note *} On the 15th May 1830, there was a remarkable shower of dust, supposed to have come from the African Coast, which fell over a vast extent of the Mediterranean; it was witnessed about the same time of the day at Malta, Sicily, and Sardinia. An account of it is given in my “Notes on the Ionian Islands and Malta,” vol. i. p. 300.

^{page 64 note †} An instance of this kind occurred during the last eruption of the Souffrière Volcano, in St Vincent, on the 30th April 1812. Although Barbadoes is sixty miles to windward, volcanic dust on that day, carried by an upper current, fell over the whole extent of the island, and was so dense in falling, as to produce the darkness of night at mid-day, and was in so large a quantity, that I saw remains of it in the soil, where it had not been disturbed, when I was there, thirty-six years after the event.

^{page 64 note ‡} In No. 73 of the “New Edinburgh Philosophical Journal,” there is a notice which I communicated, relative to this sooty deposit; and in the same paper, I mention, that after Baron Liebig, I found ammonia in rain-water, but never, as he did in Germany, obtained any traces of fœcal matter.

^{page 64 note §} If a wall for example, one such as I have watched, is not strongly impervious to drifting rain, that portion of rain which penetrates and reaches the inner surface will there evaporate and leave its saline contents,—these always accumulating, and, from their tendency to deliquesce, from attracting moisture, must render the surface almost perpetually damp,—a state equally favourable to the decay of paper-lining, and to mildew-growth.

In the West Indies, at Barbadoes, I have witnessed a like accumulation of saline matter derived from the air, even where no rain could penetrate; for instance, on mosquito-curtains, in an inner bedroom, merely well ventilated. In my work “On the West Indies, before and after Slave Emancipation,” I have pointed out the tendency to decay from climatic agencies as one of the causes of the neglect of the fine arts in those colonies.
