 The stoppage effect of a content of but 10 per cent of salt is still pronounced.

45. The Same, Continued. — The solution was now again diluted to 

 about one-half strength, thus showing about one-fourth the original con- 

 centration, and the daily run of results taken as in table 26 and fig. 24, 

 with the same vessel and float as before. The density of solution was 

 p w = 1.0295 at 2 1°, implying 4.2 grams in 100 grams of solution, or 4.4 grams
