usually kept ready for sale, in parcels of an ounce each, a practice which renders a careless substitution an error of common occurrence; the employment of a particularly coloured paper, that of _yellow_ for instance, if used universally as a wrapper for poisonous articles, upon which also the word _poison_, or _dangerous_, might be legibly printed, would to a certain degree guarantee the safety of the purchaser; but as danger might notwithstanding be apprehended in the night, a paper of a distinct texture might afford additional security; the peculiar roughness of the Dutch filtering paper which is manufactured from woollen would answer such a purpose. The labels of phials should in this particular correspond with the wrappers of dry substances; if the distinction were once generally adopted by the various dealers, it would soon become notorious to indifferent individuals, and many fatal accidents might be prevented, without the aid of legislative enactment.[219] The College of Physicians, or a mixed Committee of the Medical Bodies, might be best entrusted with the powers of regulation to which we have alluded; while to obviate the jealousy to which such an extension of their authority would be likely to give rise, a clause might be introduced, that no regulation should be binding, until sanctioned by a certain number of the judges, as is done in some other cases of inferior jurisdictions. It would be also expedient to establish some summary jurisdiction by which fumigation, whitewashing, and other cleansing operations, and the burning of infected clothes, might be effected without delay, whenever the prevalence of a contagious disease required it. The Irish Health Act (59 _Geo._ 3. _c._ 41, _see_ APPENDIX, _p._ 164) might also be extended to such places in England as by authority should be, from time to time, declared infected.
