Effects of Theelin on the Male Genital Tract.

In the meantime it may be concluded that: (1) The proteins edestin, excelsin and hemoglobin crystallize with water of crystallization, which is very readily lost. The hand pattern previously described as common to these and other proteins is produced by apparently amorphous materials resulting from the efflorescence of the crystalline compounds. (2) If care is taken to prevent the decomposition of their crystals, these proteins give typical powder patterns rich in sharp lines. Some of the observed spacings are much longer than those found from insoluble protein structures like silk, hair and tendon.
