(After Sachs.) globulins and albumoses, the latter being least in quantity. If a section of a castor-oil seed from which the oil has been removed, be irrigated with water, a part of the outer substance of the gram is dissolved, leaving still an ovoid body, in «'hich the crystal, or crystalloid, can be seen. The part dissohed consists of the albumose, which is soluble in water. If the section be then irrigated with a ten per cent, solution of common salt, the body of the grain dissolves. This is composed of a particular globulin. The crystalloid will dissolve if it be treated with a saturated solution of the same salt, showing it to be made up of another globulin. Other aleurone grains show other peculiarities of solubility, G G 2.
