for a short time. The reactions of dysalbumose, aside from its 
behavior towards sodium chloride, were found to be much the same 
as those of heteroalbumose. 
Relation of the albumoses to albumin. 
In composition, the albumoses from albumin are seen to differ from 
each other somewhat more than the albumoses from fibrin ; collec- 
tively, however, there is less difference in composition between the 
albumose bodies and the albumin from which they are formed, than 
noticed in the case of the albumose bodies from fibrin.* In the 
latter, however, there is no guarantee that the fibrin employed in 
the experiments had the actual composition assigned to pure blood- 
fibrin. The fibrin-albumoses collectively contained about 50°6 per 
cent. of carbon and 17:1 per cent. of nitrogen, while Hammarsten 
found fibrin itself to contain 52°6 per cent. of carbon and 16°9 per 
cent. of nitrogen. In our experiments, on the other hand, we have 
for comparison the composition of the albumin actually used in the 
experiments, and in the accompanying table the differences in com- 
position of the various products are plainly to be seen. 
Examining these in detail, we see that all of the products show a 
somewhat smaller content of carbon than albumin itself. With 
nitrogen, however, there is a very close agreement throughout, and 
with sulphur likewise. In the case of the fibrin-albumoses it was 
considered that the diminished percentage of carbon indicated plainly 
that the albumoses were hydration products, and that they were 
formed from fibrin by simple hydrolytic action. The results 
obtained with the globuloses did not appear to confirm this view, 
but in this case it must be remembered that the digestion of globulin 
by gastric juice may be quite a different process from albumin diges- 
tion. With albumin, however, the results, although less pronounced, 
also indicate hydrolytic action and that the products formed are 
hydration products. 
The following table shows the extent of these differences, and also 
shows the close agreement in composition between proto- and deutero- 
albumose and the so-called soluble and insoluble hemialbumose from 
egg-albumin, isolated and analyzed by Kiihne and Chittenden at the 
commencement of their study of these bodies.*
