Thesecollar pieces, the open gutters i, i, and the wastepipes to which these latter lead, are made of a com-position of alternate layers of coarse brown paperand asphalte. Some of these pipes were broughtfrom Germany, but Messrs. Barton k Sons, Edin-burgh, have succeeded, without much difficulty, inmanufacturing them. Pipes made of this materialcombine the advantages accruing from the use oflead or stoneware pipes, as they may be bent andjointed with the greatest facility, and resist the. The tables do not rest directly on the floor of thelaboratory, but on a raised platform, which extendsnearly the entire length of the room. The water,earn, and waste pipes run along the concretefloor beneath this platform. All these pipes can belaid bare at a moments notice. The steam waterand waste pipes are led along each end of the tables,in,a the two former pass up through the platform intothe compartments /,/,/, which are rather projectionsfrom, than parts of, the tables themselves.
