nepheloscopen.

Brit.

/ˈnɛfələskəʊp/, U.S.

/ˈnɛfələˌskoʊp/

Forms: 1800s nephelescope, 1800s– nepheloscope.

Origin: Formed within English, by compounding. Etymons: nephelo- comb. form, -scope comb. form.

Etymology: < nephelo- comb. form + -scope comb. form. Compare French néphéloscope (1841).In form nephelescope perhaps after telescope n.

Meteorology. Now historical.

James Pollard Espy's name for: an instrument for compressing and expanding moist air, used to study the formation of clouds.

1844 Proc. Amer. Philos. Soc. 1841–3 2 128 Mr. Espy exhibited an instrument.., which he calls the Nephelescope, intended to show the changes induced in the temperature of the air by its greater or less rarefaction.

a1877 E. H. Knight Pract. Dict. Mech. II. 1521/2 Nepheloscope, an instrument contrived by Professor Espy to illustrate the law of the formation of aqueous vapor into clouds.

1890 Science 27 June 386 The earlier investigation with the nephelescope was made without the use of a condensing syringe.

1980 Science 11 Apr. 170 (caption) On the basis of measurements of the amount of water vapor in saturated air (made with the nepheloscope, an instrument he devised), Espy reached the conclusion that when a cloud is of great height above its base its top must be much warmer and consequently much lighter than the atmosphere at that height.
