74 ENDOSMOSE. LECT. III. 



water. After some hours, we carefully measured the vo- 

 lumes of liquid contained in the endosmometers, and 

 also those of the distilled water remaining in the two ves- 

 sels, and thus we found which of the two liquids had risen 

 most in the tubes. We observed that endosmose from 

 water to a saline solution through these skins, was most 

 promoted from the internal to the external surface. By 

 determining the density of the liquids contained in the 

 two vessels, we found that in the endosmoraeter in which 

 the volume of salt water was most increased, the density of 

 the liquid was preserved better than in the other ; and, vice 

 versa, in the vessel in which the diminution of distilled water 

 was greatest, the quantity of the saline solution introduced by 

 exosmose was less than in the other vessel from which a 

 smaller volume of distilled water had disappeared. 



In the following table are given the numbers furnished 

 by two of the numerous experiments W 7 hich we made, and 

 which led us to these results. The first column indicates, 

 in tenths of cubic centimetres, the volumes of the liquids 

 in the endosmometers after the experiment ; the second 

 column, the weight of a given quantity of these liquids ; 

 the third, the volumes of distilled water found in the two 

 external vessels after the experiment ; and the fourth, the 

 weight acquired during the experiment by a given quantity 

 of water in these same vessels. The weight of the same quan- 

 tity of the saline solution, before the experiment, was 17-350 

 grammes ; and that of an equal quantity of distilled water 

 16-025 grammes.
