Nature could hardly have created anything that seems more innocuous. An invisible and odorless gas, carbon dioxide is a simple molecular linkup of just a single atom of carbon and two atoms of oxygen (CO2). It constitutes a mere fraction of the atmosphere (.03% vs. about 78% for nitrogen and 20% for oxygen) but becomes dangerous to man and other air-breathing creatures when it accumulates in concentrations higher than 10% as, say, at the bottom of deep wells or mine shafts...
...week in Rome still more was being said on the subject. Remarked Belgium's Cardinal Suenens: "People will ask, 'Is he John or is he Paul?' He will be both in his own way.

Only Cosmonaut Georgi Grechko, 46, had been slated to make a space walk; Romanenko was to remain behind at Salyut's open hatch. Both were wearing a new type of space suit equipped with a radio and an hour's supply of oxygen. Thus when cosmonauts are working outside an orbiting spacecraft, they require no umbilical link to the mother ship other than a simple tether to keep them from drifting off. Everything was going smoothly during Grechko's extraterrestrial stroll until Salyut passed over the western Pacific Ocean-out of range of Soviet ground stations. Suddenly...
...Donoghue collected the relevant information on the incident that he would later relay to the staff in the emergency room at Cambridge City Hospital. They carefully lifted the two people into special chairs and carried them out to the truck. On the way to the hospital they administered oxygen and tried to rouse the man so that they could find out what he drank. In the emergency room they transferred the two over to the waiting doctors and nurses...
