to that of osmotic pressure. Should differences exist between 

 the osmotic pressure of fluids which bathe the skin's opposite 

 surfaces, the behavior of the skin glove would then be modi 

 fied by osmotic pressure acting in conjunction with the above- 

 mentioned factors. It is therefore desirable to analyze these 

 several factors acting in conjunction with known differences 

 in osmotic pressure.

V. THE BEHAVIOR OF GLOVES OF FROG'S SKIN, WITH THE OUTSIDE 

 OF THE SKIN TURNED OUTWARD, WHEN FILLED WITH A HYPO- 

 TONIC RINGER'S SOLUTION AND SUSPENDED IN A HYPERTONIC 

 RINGER'S SOLUTION APPROXIMATELY ISOTONIC WITH FROG'S 

 BLOOD 



In all the experiments thus far mentioned the Ringer's 

 solution designated as being approximately isotonic with 

 frog's blood consisted of 7 grams of NaCl, 0.3 gram of KC1, 

 0.25 gram of CaCL, and 0.03 gram of NaHC0 3 added to 1000 

 cc. of distilled ELO. This is the formula given by Howell ; in 

 the following experiments it is referred to as the isotonic 

 Ringer's solution. In the experiments about to be mentioned, 

 in addition to this isotonic solution, there were used three 

 other Ringer solutions which differ from the isotonic solu-
