From this table it follows that a lipochrome-rich diet produces 
considerable increase of the serum-lipochrome. The great obstacles, 
impeding a control of the food used by patients in a common ward, 
are responsible for the fact that an accurate determination of the 
lipochrome taken up could not be made and that we had to be 
satisfied with an approximate evaluation. 
When comparing these figures with those obtained with sufferers 
from diabetes, it appears that the diet may be made greatly answer- 
able for the high values with this disease (See Table III). 
This tallies with the experience that, with sufferers from diabetes, 
sometimes normal values are obtained; on the other hand that a 
patient not suffering from diabetes, but accustomed to eat 7 eggs 
a day, had a lipochrome-content of 0,9. 
Both with the consumption of many eggs (xanthophyll) and with 
the taking of carrots (carotin) an increase of the lipochrome-content 
was produced. Therefore, as will also appear further on, man is 
able to take up both pigments, contrary to the cow and the fowl 
which take up respectively only carrotin and xanthophyll. 
Thus far the inquiry had shown that with a diet comprising many 
carotinoids the lipochrome-content of the bloodserum rises rather

rapidly, and that it is lowered rather soon after a diet, which is 
poor in these pigments. We also wished to examine the lipochrome- 
content of other organs. 
The provisional answer is to be found in Table IV, from which 
we deduce the following conclusions: 
1. The lipochrome-content of the various tissues is very different. 
The blood is poorest in this pigment, also when calculating its 
relation upon the dry weight of the blood, in which the water- 
content of the blood may be put at about 80°/,. Richest in lipo- 
chrome is the adrenal; after this generally follows the liver, (in 
some cases the fat contained more pigment than the liver); after 
this comes fat and lastly the spleen. Of the latter two the one 
sometimes takes precedence of the other.
