18957 thumbnail picture
Figure 24. Vereinigte Fabriken fur Laboratoriumsbedarf thermometer, manufactured by the firm of the same name. Vereinigte Fabriken fur Laboratorium sbedarf was a manufacturing concern that made all sorts of instruments for laboratories and researchers. This type of thermometer was made in 1910 after the design of the Richter thermometer.
18958 thumbnail picture
Figure 25. Schmidt thermometer. These were of the Richter design. The firm of of Schmidt and Vossberg was founded in 1912 and fabricated these instruments upon its debut. Afterwards the company became named solely "Franz Schmidt" and all thermometers of either name are generally grouped under the name Schmidt.

Mercury thermometers in the collection of the Oceanographic Museum at Monaco. These thermometers were used on board the ships of Prince Albert 1st of Monaco.
18968 thumbnail picture
Figure 30. Fuess surface thermometer built by Rudolph Fuess of Berlin about 1900. This thermometer acted in the same way as an ordinary thermometer but was meant to be used for measuring the surface waters of the sea.
18969 thumbnail picture
Figure 31. Flat model surface thermometer. Although this thermometer is named "Richard thermometer" in the museum collections, this is probably an error. The accompanying certificate identifies it as being made by Fritz Kohler of the Ostwald Institute in 1910. It was probably meant to measure the temperature of water acquired with a surface sampling bucket.
18970 thumbnail picture
Figure 32. Richter surface thermometer, used for measuring the surface waters of the sea. This model was constructed in 1911 by Carl Richter in Berlin. Little is known as to when and where this instrument was tested and used. Undoubtedly it was meant to measure the temperature of water acquired with a surface sampling bucket.
18971 thumbnail picture
Figure 33. Meyer slow registering thermometer invented by Dr. Adolph Meyer and first used on the POMMERANIA in 1871 and then by various German scientific studies. It was used down to 50 meters but would stay submerged for about an hour to register the proper temperature because it was highly insulated.
18972 thumbnail picture
Figure 34. Thermometer used with Pettersson-Nansen insulation bottle. This bottle was a version of the Pettersson bottle with improvements made by Fridtjof Nansen in 1900. This thermometer was fixed to the inside cover of the bottle while a reversing thermometer was mounted on the outside. It was first tested on board the MICHAEL SARS in the Norwegian Sea in 3000 meters in 1900.
18973 thumbnail picture
Figure 35. Muller thermometer constructed by Gustav Muller for laboratory and research studies. It acted as a "normal" thermometer which was used with the Pettersson-Nansen insulation bottle. Because of the time for the temperature to equilibrate in the insulation bottle, the time to take a measurement was prolonged.
18974 thumbnail picture
Figure 36. Nansen thermometer for use with a water sampling bottle. This thermometer was conceived by Fridtjof Nansen in collaboration with Vagn W. Ekman . This was not a reversing thermometer but was used in an insulated bottle and then brought back to the surface for reading. It was tested on the FRITHJOF in 1910 at many hundreds of meters.
18975 thumbnail picture
Figure 37. Jacob thermometer devised by Martin Knudsen and constructed by Friedrich C. Jacob of Copenhagen. This thermometer was mounted inside an insula ted bottle that was lowered from an underway ship. This thermometer was of a classic design that had nothing particularly new.
18976 thumbnail picture
Figure 38. Knudsen thermometer devised by Martin Knudsen for use with an insulated water sampling bottle. Little is known about the testing or use of this thermometer.
18977 thumbnail picture
Figure 39. Knudsen thermometer constructed by the firm of Siebert and Kuhn. Little is known about this instrument.
18978 thumbnail picture
Figure 40. Aime's mechanism devised by Georges Aime in 1841 for triggering the release of water sampling bottles. Although the records of Aime's tests of this mechanism are not available, it seems that by using this mechanism that he was the first to take a series of water samples from bottles strung on the same cable at a number of different levels within the water column.
18979 thumbnail picture
Figure 41. Helical mounting mechanism of Negretti and Zambra. This mechanism was meant to cause the reversing thermometer of Negretti and Zambra to flip at the required depth. The helical screw would measure the depth on the way down and release the mounting at the desired depth. James Ferguson of the CHALLENGER modified this mechanism and tested it in the Sulu Sea at over 4000 meters
18980 thumbnail picture
Figure 42. Negretti and Zambra portable ballast mounting mechanism upon returning to the surface. This was designed to eliminate some problems associated with the mounting mechanism used on the CHALLENGER. This modificatio n was made in 1878 and is described in the scientific literature of the day..
18981 thumbnail picture
Figure 43. Magnaghi helical mounting devised by Giovanni Battista Magnaghi in 1881 near the end of his command of the Italian oceanographic expedition on the WASHINGTON. This mechanism was certainly inspired by the Sigsbee bottle mounting as well as the 1874 Negretti and Zambra water bottle mounting. The helical principle was used profitably by a many inventors and instrument makers.
18982 thumbnail picture
Figure 44. Magnaghi helical mounting (improved model.) This model resulted from the suggestion of Giovanni Battista Magnaghi to the London instrument maker s Negretti and Zambra, in 1881, to follow the ideas developed on the Italian navy ship WASHINGTON. Left: before reversing. Right: after reversing.
18983 thumbnail picture
Figure 45. Milne-Edwards mounting developed by Professor Alphonse Milne-Edwards for use with reversing thermometers on the TALISMAN scientific expedition of the French National Marine Administration in the North Atlantic in 1883. Two innovations were associated with this instrument. A slightly modified version of this mounting made by Paul Duimage was used on the HIRONDELLE.
18984 thumbnail picture
Figure 46. Rung mounting designed by Captain George Rung, an assistant at the Meteorological Institute of Denmark. In 1883 he described a new mechanism for releasing the reversing thermometers by means of a messenger system. With this system numerous bottles mounted on a cable could be released at various depths in series. Details of the original testing of this mechanism are unknown.
18985 thumbnail picture
Figure 47. Scotch messenger mounting invented by Hugh R. Mill who was inspired by the mounting devised by George Rung. Mill also incorporated design elements of the Magnaghi mounting. This instrument was first used in a series of observations from the ARK in 1884 in studies undertaken from the Scottish Marine Station at Granton.
18986 thumbnail picture
Figure 48. Scotch messenger mounting. Left: before reversing. Right: after reversing. This equipment was probably used by Prince Albert I of Monaco. The design is very similar to that used in the Magnaghi helical mounting, but instead used a messenger activating a lever to invert the reversing thermometer.
18987 thumbnail picture
Figure 49. Tanner helical mounting devised by Commander Zera Luther Tanner, USN , commanding officer of the U. S. Fish Commission Steamer ALBATROSS. It is very similar to other types of helical mountings in its design and operation. Tanner reported that it was relatively light but was very robust in operation.
18988 thumbnail picture
Figure 50. Luksch mounting and messenger system for inverting reversing thermometers. Invented by the Austrian Joseph Luksch and used during the scientific campaign of 1895-1896 on the POLA in the Mediterannean Sea and Red Sea.
18989 thumbnail picture
Figure 51. Pettersson universal apparatus designed by Otto Pettersson in 1904. This instrument sampled plankton and water, as well as measuring temperature, current velocity, and current direction. It was used for the first time in the Skaggerak and also in the Baltic Sea. The thermometer is placed in the horizont al cylinder shown at the back of the image.
18990 thumbnail picture
Figure 52. Richter mounting and messenger. This mounting was used by Franz Doflein for the measuring the temperature of the water in shoal depths in Sagami Bay, Japan. The thermometers used in this mounting were manufactured by Negretti and Zambra. Left: before reversing. Right: after reversing.
18991 thumbnail picture
Figure 53. Richter mounting with helical reversing mechanism. This mounting is very similar to that in Figure 52 but was used in great depths. It was used by Franz Doflein off the coast of Japan in 1904.
18992 thumbnail picture
Figure 54. Richter mounting with messenger and pump brake for slowing reversing action. With the earlier models used by Doflein, the mounting would flop over too quickly and jar the mercury column sufficiently to cause its separation. To slow down the reversing motion, a piston pump mechanism was installed on the mounting. This mounting was employed by Doflein off the coast of Japan in 1904.
18993 thumbnail picture
Figure 55. Stahlberg mounting devised by Dr. Walter Stahlberg, conservator of the Museum fur Meereskunde at Berlin. This mounting could be used with either a messenger for reversing in relatively shallow water or a helical system for deep water. It was used on board the German vessel MOWE off the coast of Africa in 1911.
18994 thumbnail picture
Figure 56. Negretti and Zambra mounting with chain and messenger reversing system. This system was devised in 1912 by Negretti and Zambra as a modification of the "Scotch" mounting.
18995 thumbnail picture
Figure 57. Kohler mounting and messenger system. This system was commercialized by Fritz Kohler at about the beginning of the Twentieth Century. However, its simplicity and fragility caused it to be little used.
18996 thumbnail picture
Figure 58. Insulated water bottle and thermometer devised by Rudolph Fuess about the end of the Nineteenth Century. It was used notably by German vessels.
18997 thumbnail picture
Plate 2. Magnifying glass devised by Fridtjof Nansen for reading thermometer scales. The thermometer is placed such that the two notches designated "c" are on the thermometer; the thermometer is adjusted such that the top of the mercury column is located at point "d"; and the reading glass is focused for reading the thermometer by turning the interior tube "a" within tube "b".
18998 thumbnail picture
Figure 59. Nansen microscope for precise reading of thermometers. This instrument was designed by Fridtjof Nansen to facilitate the reading of thermometer scales and to better be able to estimate values between graduations of the scale and also to better remove parallax errors. This instrument was designed about 1910 and constructed by the German Ernst Leitz.
18999 thumbnail picture
Figure 60. Richter microscope for reading thermometers. Much less sophisticate d than the Nansen microscope, was frequently used to read with good precision the scales of reversing thermometers. This instrument was described and conceived by the firm of Richter and Wiese in the early 1900's.
