NOTE: This image is a focus stacked image of "Medical mercury thermometer with velvet-lined cardboard box - focus stack (2020-05-25).jpg" consisting of 9 images that were merged using Zerene Stacker Version 1.04 Build T2019-10-07-1410 (licensed). As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions. العربية ∙ Deutsch ∙ English ∙ español ∙ français ∙ 日本語 ∙ македонски ∙ português do Brasil ∙ русский ∙ slovenščina ∙ ไทย ∙ українська ∙ 中文（简体） ∙ 中文（繁體） ∙ +/−

en: Medical mercury thermometer.

• Glas tube.
• Original velvet-lined cardboard box with clip.
• Manufactured in Germany before 1920 by "C. & Cie D.".
• The numerals are obviously hand-painted.
  They are arranged to be read when held in vertical position.
  This differs from the horizontal arrangement of numerals as displayed in the external link depicting an almost identical model together with its protective casing (see below).
  Both hand-painting and vertical arrangement of numerals indicate an even earlier production date, maybe 1900-1915.
  Note: according to numerous images mercury medical thermometers later displayed numerals that were preferredly arranged for horizontal viewing.
• Length of glass tube: 126 mm.
• Image taken in May 2020.
