 E.M.,retemh-abile; G.E., gas-gland epithelium. The new gland now described is 

 situated round the veins at the proximal pole (pole remote from the glandulai 

 epithelium) of the rete mirabile.

swim-bladder. These granules, thus abstracted by the gland-cells 

 from the blood, are carried away by special ducts appertaining to 

 the gland (text-fig. 80). The discovery of this important gland 

 in several genera — Gobius, Syngnathus, Fierasfer, Box, and 

 others — confirms Jseger's view as to the mode of generation of the 

 bladdei- oxygen. The rete mirabile of the gas-gland apparatus is
