Excerpt: ...nitrate according to Volhard's process, the crystals for this purpose being dissolved in dilute alcohol: 0.1970 gram required 10.5 c.c. N/10 AgNO3. Br = 42.63 p.ct., calculated 42.32 p.ct. This method of applying hydrogen bromide in ethereal solution is, of course, unsuitable for investigations where a higher temperature has to be employed, or where long standing is necessary, since, under such circumstances, the ether itself is attacked. Wishing to make investigations under these conditions, the authors have tried several solvents, and, at present, find that chloroform is best suited to the purpose. In each of the following experiments, 10 grms. of the Pg 88 substance were covered with 250 c.c. of chloroform which had been saturated at 0
