In the uniform injection of considerable quantities of normal 



salt solution into the blood, the flow of urine, after about an 

 hour, becomes fairly constant. If an average amount of i cc. 

 in I minute be introduced, the secretion of urine during the first 



two or three hours is usually slightly less than the amount of 



fluid injected. After this time, when no other salts have been 

 added, the quantity injected and the quantity secreted may become
