[Footnote 12: See Orton on Cholera, who is most explicit upon this point, and cites from the India Reports:--so that the distinctions attempted to be drawn in this respect between the "cholera of India," and that of other countries, are, after all, _quite untenable_.] Little need be said respecting the pure assumptions of Sir Gilbert as to the movements of the malady by land and by water, for those vague and hacknied statements have been again and again refuted; but we may remark that whereas all former accounts respecting the cholera in 1817, in the army of the Marquis of Hastings, state that the disease broke out somewhat suddenly in the camp on the banks of the Sinde, Sir Gilbert, without deigning to give his authority, makes the army set out for "Upper India accompanied by this epidemic." We find that Mr. Kennedy, another advocate for contagion in cholera, differs from Sir Gilbert as to the disease having accompanied the grand army on the march; for he says the appearance of the malady was announced in camp in the early part of November, when "the first cases excited little alarm." In referring, in a former letter, to the sickness in the above army, I showed from the text of the Bengal report, how a change of position produced a return of health in the troops; but Mr. Kennedy states that the disease had greatly declined a few days before the removal, so that it had lost "its infecting power." Nevertheless it appears by this gentleman's account, a little farther on, that "in their progressive movement the grounds which they occupied during the night as temporary encampments were generally found in the morning, strewed with the dead like a field of battle"! This gentleman tells us that he has laid down a law of "increase and decline appertaining to cholera," by which, and the assistance of _currents of contagion_, it would appear all these things are reconciled wonderfully. Several of the points upon which he grounds his belief of contagion have been already touched upon in these letters, and the rest, considering the state of the cholera question in Europe just now, may be allowed to pass at whatever value the public may, after due examination, think it is entitled to. Let it be borne in mind that all contagionists who speak of the cholera in the army of the Marquis of Hastings, forget to tell us that though many thousand native followers had fled from that army during the epidemic, the disease did not appear in the towns situated in the surrounding country, _till the following year_, as may be seen at a glance by reference to Mr. Kennedy's and other maps.
