I prefer however to form it entirely of glass or porcelain, as such materials are least affected by the action of the liquids used for in¬ halation. 5 Instead of using a cylinder with internal passages or tubes of paper I may employ a cylinder of sponge or other similar absorbent substance in the said glass tube for holding the liquid, but I prefer to use the said cylinder formed with the small ducts or tubes, as the latter permit a very free passage of the air and its thorough saturation with the vapour 10 of the said liquid when it is drawn through the said apparatus by inhalation. In witness whereof, I, the said William Robert Lake, have hereunto set my hand and seal, this Thirtieth day of October, in the year of our Lord One thousand eight hundred and seventy- 15 four. WM.
