By further studies the authors confirm their original conclusion that 
“living protoplasm (or the albumen therein) is chemically different from 
the dead substance ; the chemical difference consists, in all probability, 
in the presence of aldehyde groups in the molecule of the living proto- 
plasmic albumen.”
