After a half-hour's soaking in this solution, heated to 104° F., the wool absorbs 1½% of chlorine. It can then be washed in hot or cold water without shrinking...
...experiments at keeping frescoes fresh. First sign of success in their collaboration came when they used a spray of glycerine, lime, marble dust and water. But no matter how little glycerine they used it would appear later in small beads on the surface of the plaster. Then they tried butyl alcohol (butanol) with the same ingredients. This worked, but made the plaster surface too soft to work on. The final formula was the simplest: equal parts of butanol and water. Muralist Rivera, pleased as Punch, confirmed their claim that spraying walls with this preparation every three or four hours enables...

The stench safety method has been adopted by the American Standards Association which suggests to mine operators how best to conserve their employes' lives. Although the U.S. Bureau of Mines cannot force operators to obey American...
