Artificial Mothers' Milk. 115 



3. Milk sugar possesses only about one-third of the 

 sweetness of cane sugar ; we are, therefore, able to mix 

 three times the quantity to a nourishment without pro- 

 ducing a repugnant sweetness. 



4. It is not transformed like the other sugars into 

 glykogen, has an enhanced combustability and passes 

 easily into the urine. 



5. Maltose and cane sugar are the most rapidly 

 absorbed, milk sugar but very slowly ; 70 to 80 per 

 cent, of the former in one hour, of milk sugar but 20 

 to 40 per cent., depending on the strength of solution. 



6. The accumulation of the rapidly absorbed sugars 

 in the blood produces very notable changes in the 

 functions of the apparatus of circulation, which per- 

 sist until the blood is relieved of this excess of sugar. 

 The pressure of blood is heightened, the vessels be- 

 come expanded, the pulse is augmented, circulation 

 is so much accelerated that double the quantity of 

 blood passes through the same vein during a meas- 

 ured span of time. Milk sugar produces quite a 

 unique effect on the circulation ; although the blood 

 pressure is equally enhanced if given in large doses, 

 yet the pulse is not accelerated, but rather diminished, 

 producing an ample systole. The heightened pres- 

 sure of blood is caused by the irritating effect the 

 other sugars have on the heart and its vessels ; the 

 diminishing of the pulse is ascribed to the specific 

 influence of the milk sugar on the checking appar- 

 atus of the heart.
