Human and other viscera may be transmitted by post to chemical examiners for analysis subject to the following conditions:-(a)The suspected viscous or other material to be sent for examination shall be enclosed in a glass bottle or jar, fitted with a stopper or sound cork.(b)Great care shall be taken that the stopper or cork of the bottle fits tightly. This precaution is especially necessary when alcohol is used as a preservative; in such cases a ring of bee's wax or candle-wax shall be placed round the lip of the bottle so as to cover the shoulder of the stopper. The stopper shall be carefully fastened down with bladder or leather and sealed.(c)The glass bottle or jar shall then be placed in a strong wooden or tin box, which shall be large enough to allow of a layer of cotton, at least 18 millimeters thick, being placed between the bottle or jar and the box.(d)The box itself shall be encased in cloth, which shall be securely closed and sealed. The seals shall be at intervals not exceeding 7 ½ centimeters along each seam. All the seals shall be of the same kind of wax and shall bear distinct impressions of the same device. The device shall not be that of a current coin or merely a series of straight curved or crossed lines.
