And here's a followup, snipped from "Man under the sea" (Man explores the sea in England), 1956 by James Dugan, p. 14, 15: Fleuss' first dive in open water (his certification?) was in Wooten Creek, Isle of Wight. He was rowed out wearing bathing drawers and his breathing set. To sink himself, he put lead and iron weights on his belt until his friends insisted he be tethered to the rowboat. The medical texts he had read stated that breathing large excess of oxygen would cause "exitability or feverish rise in temperature". **** Fleuss figured he might reduce the risk by inflating the breathing bag with air before donning the mask and then hand-valve oxygen as needed to keep the pressure in the bag. **** --------------------------------------------------------------- Here is my intelligence test: (Email me your answers...) If you were given ONLY ONE SHOT at a machine that can perfectly duplicate ANYTHING AT ALL WITHOUT RESTRICTIONS (down to the subatomic level), what is the (only) thing that you would copy? ---- Marc Dufour ---- [\] ---- http://www.cam.org/~mdufour ----
