After a certain time the solution was [loured ofF and a new piece of paper and fresh dye solution, previously warmed, or cooled respectively, added and a different time of action allowed. The flasks were thoroughly shaken at frequent intervals to allow access of the solution to the whole surface of the paper. This shaking caused the separation of hits of paper which rendered it necessary to allow the solution to deposit before making colorimeter observations ; neglect of the precaution caused the loss ot several of the earlier observations. Filtration is naturally inadmis- sible. The results were as follows, the colorimeter readings expressing the relative percentage of dye left in solution, the original solution = 100. r , â , ,⢠Colorimeter readings Duration of action 50^ 10 5 minutes 95 circ. 8 »> 90 ... 20 » 85 ... 33 >i ... 90 40 »> 80 ... 100 »> 77 70 200 '> ... 60 5 hours 75 ... 7 â ... 55 H >» 75 48 H ?» ... 45 Fig. 4.
