This type of pocket thermometer was first made
by FRÉDERIC HOURIET followed by URBAN
JÜRGENSEN and ABRAHAM LOUIS BREGUET.
It was described by Houriet in an advertising
leaflet, unfortunately undated. The bimetallic
thermometer device is extensively explained
and illustrated by Urban Jürgensen in "Principes
Généraux de l'Exacte Mesure du Temps par les
Horloges", Copenhagen, 1805, pp. 245-253, pl.
XIX. An almost identical thermometer signed
`Fred Houriet` was sold by ANTIQUORUM,

illustrated in The Jurgensen Dynasty by John
Knudsen p. 129.
