    PAGE 12- -13 13- -14 15- -18 VI TABLE OF CONTENTS. I^either in blood nor urine does the sugar constituent exclusively consist of glucose ...... Experimental representation of the amount and character of the sugar normally present in the hlood of various animals in fed and in fasting states ..... Amount and character of sugar present in normal urine of varioiTS animals in fed and in fasting states Point of difference between the sugar belonging to normal urine and to that associated with glycosuria as an abnor- mal condition ....... 18—19 Intravenous injection into the rabbit of various quantities of saccharose, lactose, maltose, galactose, Issvulose, and dex- trose. Amount of sugar present in the blood at different times afterwards, and also the amount of sugar eliminated with the urine ...... 19—25 Subcutaneous injection of the same sugars. State of blood and urine after. Evidence of dextrose being moved within the system into a lower ciipric oxide reducing sugar . 26—29 Saccharose, lactose, and maltose non-assimilable within the circulatory system, and hence, if introduced into it, they- filter off with the urine. Galactose, Isevulose, and dextrose, in like circumstances, assimilable to a limited extent, but to nothing approaching the extent to which they are found to be assimilable when passing throiigh their natural channel from the alimentary canal .... 30—31 Respiratory quotient shows that carbohydrate ]3asses from the seat of absorption to the tissues, but the state of the blood and urine after food shows that it cannot do so in the form of free sugar ..... 32—33 Assimilation not to be confoiuided with utilisation. The one an act of incorporation with protoplasm, the other an oxi- dation of assimilated material .... 33—34 Qu.estion of how the transport of carbohydrate through the circulatory system takes place. Glucosides long known to exist in the vegetable kingdom. Recent recognition in the animal kingdom. Reference to author's communica- tion to the Royal Society On the Glucoside Constitution of Proteid Matter . . . . . . 34—36 Entry of carbohydrate into the proteid molecule a point of physiological importance on account of the size of the molecule into which it enters protecting it from discharge by filtering off with the urine .... 36 Procedure for liberating carbohydrate from proteid matter . 37 Estimation of proteid carbohydrate by the potash process . 37—39 Estimation of proteid carbohydrate by the hydrochloric acid process . . . . . . . 39—40
