Photograph 2. - 16 - The apparatus as a whole consists mainly of a combination ofstandard parts, found individually in any catalogue, simply connect- j ed in the proper manner by means of glass tubing, etc., and heldin place by suitable clamps. With the exception of the musclechamber and the titration chamber, which were made to order at jj small expense, all other parts and connections were made in the laboratoiiy, using an oMinary Bunsen blov/pipe. Practically all of the standard parts have remained intact and can be removed fromthe apparatus at any time and put to other usages. The glasstubing generally used has an inside diameter of 3 m m. With thissize tubing, no blocking up by moisture-collection ever happens,as is the case in Fletchers apparatus with tubing of 1 m.m. bore. The apparatus is set up on an ordinary laboratory benchbuilt solidly against the wall. Projecting from the wall, 1.1meters above the table is a stout shelf 20 cm. wide, which supportsthe two large bottles con
