LIQUIDS AND ALLIED EXPERIMENTS.

65. Summary. — The data found in the above observations have been 

 summarized in table 46, in which the system of gas and liquid under- 

 going diffusion is specified in the first column, the table from which 

 the data are derived in the second, and the vessel in which the experi- 

 ments were made in the third. The vessels A and H were of the double- 

 tube pattern, the remainder being single-tube apparatus. The latter 

 admit of much easier treatment ; being much less complicated, they prob- 

 ably lead to results which are for this reason more trustworthy, particu- 

 larly as every apparatus is eventually standardized by the results of the 

 diffusion of air through pure water.

The fourth column contains the number of cubic centimeters lost by the 

 diver (by diffusion) per day, the fifth the corresponding loss, i> , per second, 

 and the sixth the duration of the experiment in days. The quantity 

 h" in the seventh column shows the height of the free surface of liquid in
