Marriott and Howland (1), in 1916, showed that in the blood of uremic patients the serum calcium is low but that there is an increased concentration of inorganic phosphorus. That there might be some relation between the rise of phosphate and the fall of calcium was first suggested by Binger (2), who injected solutions of 0-phosphates intravenously into dogs and observed an elevation of inorgani...

The usual method employed in determining the acidity of milk is to add a few drops of a solution of phenolphthalein as indicator to 100 cc. of milk and then titrate with 6 NaOH. By the use of this method it is found that 100 cc. of milk, when strictly fresh, will require the addition of 15 to 20 cc. of the alkali in order to produce a faint but permanent pink coloration. The acidity of fresh mi...

Since this inference seems unwarranted by the observations made during the preceding studies with tissue cultures, it is desired to explain wh...
