LECTURE III. 



organs of dogs which were well fed with carbohydrates and meat shortly 

 before their death. The following table gives a summary of the results 

 obtained: 



PER CENT OF GLYCOGEN IN THE ORGANS. 



100 grams of glycogen in the body are distributed in the different parts of the 

 dog as follows: 



It is evident from the above table that the amount of glycogen present 

 in the different organs varies greatly. At all events, it is never possible to 

 draw conclusions concerning the amount of glycogen present in any given 

 organ from a knowledge of the amount contained in another organ or 

 even in the whole body. 



Besides the carbohydrates which have been mentioned up to this point, 

 there are quite a number of other compounds belonging to the group of 

 polysaccharides which have been observed in blood, in milk, and es- 

 pecially in urine. They have been designated partly as animal gums/ and 

 partly as dextrin-like substances, 2 etc. The last-mentioned are found in 

 large quantities in the urine of diabetics, although it is quite possible that 

 such products may be present to some extent even in normal urine, because 

 boiling it with mineral acids causes the formation of humin substances,
