Summary
-
1.
Acid mucopolysaccharides, containing sulphonic acid groups are present in the cavity of the saccus vasculosus and also in the globules, “hairs”, and basal corpuscles of the coronet cells.
-
2.
Proteins, probably belonging to the structural frame of the cell body, can be determined.
-
3.
The acid mucopolysaccharide inside the cavity of the organ does not contain proteins and lipids in demonstrable quantity.
-
4.
The presence of cystine molecules within some coronet cells seems highly probable.
-
5.
The localisation and the mode of synthesis of the acid mucopolysaccharide inside the coronet cells is discussed.
