PRINTED BY W. CLOWES AND SONS, STANFORD STREET. FOOTNOTES:

[1] The first half of the storm, in the case before alluded to, is that N.E. of the line N.W.—S.E., fig. 1, comprising the easterly and southerly winds; and the latter half, that S.W. of the same line, comprising the northerly and westerly winds.

[2] This table is also applicable to the hurricanes in the neighbourhood of Mauritius in the southern hemisphere, where all the phaenomena are reversed; the motion of the hurricanes being towards the S.W., and the rotation in the direction of the hands of a watch, the same barometric and anemonal phaenomena are experienced as in a hurricane in the northern hemisphere moving towards the N.E.

[3] By the officer of the watch being charged with this duty, and its being executed under his immediate superintendence, it is apprehended that a register may be kept with great regularity.

[4] These papers may be obtained from Messrs. W. H. Allen and Co., Booksellers to the Honourable East India Company, No. 7, Leadenhall Street, London.
