Studies in Milk Secretion 



The results are similar to those of the last series of experiments 

 but the action is more marked. It will be seen that the yield of milk 

 in no case has returned to normal within the few days of the experiment 

 though it did eventually. It would seem that phloridzin has a rather 

 long-continued action; this confirms the work of Paton and Cathcart 

 who found sugar in the urine for a long time after the administration 

 of phloridzin. 



In two cases out of the three the fat percentage at the end of the 

 experiment was below that at the beginning, although the daily yield 

 of milk had not returned to normal. 



Series (c). Phloridzin was injected into goats under normal condi- 

 tions of feeding. It was thought that this would reduce the amount 

 of stored carbohydrates in the body and perhaps thereby limit the 

 amount of milk secreted. Table III below gives the results obtained 

 in the four experiments performed.
