| -2- American gasoline at atmospheric pressure, whereas it will cause evaporation of 37% of English gasoline under the same conditions. Reducing the pressure will probably cause an even greater difference so that at say half the atmosphere we might be able to evaporate nearly all the English gasoline but probably not more than 30% of American gasoline at a temperature of 175°F.{Mr Friese} Yours truly, ROLLS-ROYCE OF AMERICA, Inc.
