Letter Concerning a Negretti & Zambra Barometer
Cat. No. PС-2026-026
An unusual piece of private correspondence documenting the investigation of a historical Negretti & Zambra barometer in the Netherlands during the 1970s.
The letter was written on 13 August 1974 by J. Warners-van Veen of Rijswijk to A. Johansman of Zeist. Warners-van Veen thanks the recipient for the particularly interesting documentation that had been sent to her and notes that a signed “blue brochure” was presumably intended to be returned. This reference suggests that Johansman had already supplied comparative or historical material in an attempt to identify or explain the barometer.
