Réaumur pronunciation

Reaumur was the first that reduced thermometers to a common standard, so as that the cold indicated by a thermometer in one place, might be compared with the cold indicated by a thermometer in another ; in other words, he prescribed rules by which two thermometers might be constructed that would exactly coincide with each other through all the changes of heat and cold : he fixed the middle term, or zero, of his division of the tube, at the point to which the liquor rises when the bulb is plunged in water that is beginning to freeze ; he prescribed a method of regulating the divisions in proportion to the quantity of liquor, and not by the aliquot parts of the length of the tube ; and he directed how spirits of wine might be reduced to one certain degree of dilatability.

He found also that eggs might be kept fresh and fit for incubation many years, by washing them with a varnish of oil, grease, or any other substance, that would effectually stop the pores of the shell, and prevent the contents from evaporating ; by this contrivance eggs may not [p. The Times.
