A, the viscus, or organ, enveloped by serous membrane; B, layer of membrane lining cavity; C, membrane reflected to envelop viscus; D, outer layer of viscus, with blood-vessels at E communicating with the general circulation.

The outer membrane corresponds to the Ectoblast, or outer cell sac, the Purkinjean vesicle to the Mesoblast, or inner cell sac, while the dot in the centre answers to the Entoblast.

On les trouve abandonnés à sa porte, nus comme des enfans nouveau-nés, faute de membrane cutanée, ou même papyracée.

In rarer cases the thickening and congestion of the membrane increases, and the articular capsule becomes so distended with the increased synovia and accumulated inflammatory discharges that a kind of chemosis occurs.

Later, as destruction of the synovial membrane proceeds, the flow of synovia is stopped, while the pus formation goes on until finally nothing but pus and dead tissue products fill the cavity.

A second membrane receiver was constructed, and for many more weeks the experiments continued.

It is about the contact of flame with the tender mucous membrane surfaces of the mouth and throat that Joe, as a fire-eater, was most concerned.
