Of places in which colds are caught it is not necessary to be particular. For, as a late Justice of the Court of Queen's Bench laid it down in summing up to a jury, in a case of sheep-stealing, after some time had been wasted in showing that the stolen sheep had been slaughtered with a particular knife--any knife will kill a sheep--so it may be said that a cold may be caught any where: on the moor or on the loch; traveling by land or by water; by rail or by stage; or in a private carriage, or walking in the streets; or sitting at home or elsewhere, in a draught, or out of a draught, but more especially in it. Upon a statistical return of the places in which colds have been caught, by persons of both sexes, and under twenty-one years of age, founded upon the answers of the patients themselves, it appears that more colds are caught upon the journey in going to school, and at church, than at the theatre and in ball-rooms. Upon a similar return from persons liable to serve as jurymen in London and Middlesex, it appears that a majority of colds is caught in courts of justice; to which statement, perhaps, more confidence is due than to the former, as it is not known that Dr. Reid has ventilated any of the churches or theatres in the metropolis. Indeed, if the ancient physical philosophers, who had many disputes upon the first cause of cold, had enjoyed the advantage of living in our days and country, they might have satisfied themselves on this matter, and at the same time have become practically acquainted with the working of our system of jurisprudence, by attending in Westminster Hall, when they would go away perhaps with some good law, but most certainly with a very bad cold in their heads. Upon the returns from ladies with grown-up daughters and nieces, it appears from their own statements, that more colds are caught at evening parties than any where else; which is in remarkable discrepancy with the statements of the young ladies themselves, as before mentioned. The same curious want of agreement is found to prevail as to the number of colds caught on water-parties, pic-nics, archery-meetings, and the like, which, according to one set of answers, never give rise to colds, but which would certainly be avoided by all prudent persons if they gave implicit belief to the other.
