Irregular extensions of hyaline fluid and protoplasmic inclusions (Fig. 6). 4. Peripheral extensions of hyaline fluid. Syneresis is an entirely different response from that which is here termed outflow (cf. Fig. 22a and 226). OUTFLOW OF MATTER Normal protoplasm may rupture the surface and produce an outflow as a result of pressure created by a stream block. This matter undergoes reversible coagulation, recovers and produces a new surface. There is no separation of the protoplasm into several phases. Quinine sulphate caused a different type of outflow v\hich appeared to be a toxic effect. The surface possessed a ragged opening which was probably caused by death changes and loss of elasticity. This outflow consisted of hyaline fhiid and microsomes. There was, therefore, a protoplasmic separation in this type of outflow. The microsomes were under- going Brownian movement. Later, the microsomes aggregated and the hyaline fluid was found to be miscible with the aqueous solution on the coverslip. Ephe- drine and atropine also produced an outflow. CHANGES IN PHYSICAL PROPERTIES a) I'iscos \'iscosity changes were caused by all the reagents. The outer treated regions were affected more than the inner ones. The changes differed with each reagent (cf. quinine hydrochloride and atropine, Table I). b) Elasticity The elasticity generally increased on application of the toxic substances, but it was to be observed only after the protoplasm underwent structural changes. c) ExtensihUity An increase in extensibility due to treatment was noted in protoplasm which had not coagulated. Quinine hydrochloride produced a rather uniform coagulum which possessed little extensibility. d) Tenftcious qualities There was an apparent relationship between extensibility and tenacity. A coagulum was rather difficult to tear and scarcely stretched. Protoplasm w
