The bile secreted from a portion of the rabbit's liver far advanced 

 in an atrophy of the sort described, and competing with a large 

 liver mass which received the entire portal stream, is almost color- 

 less and may give but a weak Pettenkofer reaction. Glycogen, 

 though, is present in the atrophic cells in approximately the same 

 amount and distribution as in the hypertrophic parenchyma of 

 the same animal. 



The type of local liver destruction here considered, which 

 is dependent upon hypertrophy elsewhere, contrasts interestingly 

 with the local hypertrophy dependent upon destruction which 

 has long been familiar to pathologists. 



The fact that a parenchymal shift follows local changes in 

 the portal stream has a bearing on the cause of certain alterations 

 in the shape of the normal liver which have been attributed to 

 pressure from the surrounding organs.

The utilization of the calcium of carrots by man. 



By Mary Swartz Rose with the cooperation of Rena S. Eck- 

 man, Edith D. Brownell, Edith Hawley and Ella Woods. 



[From the Department of Nutrition, Teachers College, Columbia 



University.] 



Four healthy young women were given rations with a calcium 

 content approximating their minimum requirement, and calcium 

 balance determined from analysis of food, urine and feces. In 

 two cases the experimental period was about two weeks, and in the 

 other two, about three weeks. In two cases the carrot period 

 was preceded by a period in which the calcium was derived chiefly 

 from milk. In all cases the subjects had had their digestive 

 capacity tested by previous digestion experiments. 



About 400 grams of cooked carrot were eaten by each subject 

 daily, furnishing from 55 to 84 per cent, of the calcium ingested. 

 In all cases but one there was a positive calcium balance, and in 

 this case the loss was small. In one case, the balance was nearly 

 the same on a diet in which 55 per cent, of the calcium was derived 

 from carrots as on one in which 70 per cent, was furnished by
