Figure 71. A Mohr-Westphal density balance. This instrument was first described in 1832 by the German chemist Carl Friedrich Mohr. It is a balance with two arms, where the equilibrium is reached by adding weight on a tray. This type of instrument was modified by G. Westphal who replaced the tray with an adjustable counterweight. Julien Thoulet used this type of instrument in his studies.

Figure 72. Pycnometers for the measurement of the density of sediments. According to Thoulet, the apparent density of a sediment is the weight per cm cubed of the dry sediment when compressed as much as possible. The true densit y is the relation of the weight of the sample relative to the weight of an equal volume of distilled water at 4C. Thoulet studied these sediment properties.

Construction date and details of study conditions are unknown.

Figure 5. Compact luxmeter, used for study of light in air. Simplicity of design and use have joined with greater and greater precision of measurement in this mass-produced industry instrument. Although apparently an instrument used in meteorology, it is shown here because of the relationship between solar radiation and photo synthesis.

Figure 16. Cases of bottles for preserving water for salinity measurements. The bottles were placed in crates partitioned to protect against shock. The flasks were sealed to prevent evaporation and contamination. Flasks were closed by ground glass stoppers, but the bottles were closed with rubber rings and and metal levers for ease of sealing and opening.

12043 thumbnail picture
Figure 19. Apstein's mud sampler - an instrument described in the catalog of the German Section of the International Oceanographic and Marine Fisheries Exposition of 1906 as a sediment sampler although it appears to be more likely that it was meant to be a water sampler used in the study of plankton by Dr. Carl Apstein.
