2dly. That with these same liquids it is less with the skin 

 of the eel than with that of the frog. 



3dly. That we have a current of endosmose from water 

 to alcohol, stronger with the skin of the frog than with the 

 eel skin, and with the latter more energetic than with the 

 skin of the torpedo. 



4thly. That this current through the skin of the frog still 

 continues strongest from the water to alcohol, although the 

 skin be not placed, with respect to the liquids, in the 

 manner most favourable for the production of the pheno- 

 menon. 



5thly. That the intensity of endosmose for the same skin 

 varies for each liquid ; and for this reason, these liquids 

 ought to be arranged for the different skins in the follow- 

 ing order, commencing with that which gives the strongest 

 current, and proceeding to that which yields the weak- 

 est : 



Order of Intensity of different Liquids for different Skins. 



These later results prove, that the order in which Dutro- 

 chet arranged these liquids, relatively to the intensity of 

 endosmose which takes place between them and water, 

 ought not to be considered as constant for every case. 



Class 2. Experiments with the Gastric Membrane of the 

 Lamb, Dog, and Cat, and Gizzard of the Fowl. We shall 

 reserve our general conclusions from what we have now
