Hydrometer methods are based on the same principle as pipette methods [for grain size analysis by means of settling velocity. ] The density of a suspension(and thus its solid matter content) is measured at given intervals after initiation of sedimentation with a hydrometer inserted into the suspension.... The hydrometer method is not very accurate because of errors in reading the hydrometer, displaced particles, disturbance of the sedimentation process by the insertion and removal of the hydrometer, etc. Hence this process is but rarely used in sedimentological investigations. 1, record 1, English, - hydrometer%20method

La méthode [densimétrique] la plus simple, et cependant assez précise, est celle de l'hydromètre. [...] la méthode consiste à suivre la variation de la densité d'une suspension en sédimentation en fonction du temps. La densité est fonction de la concentration en particules solides, le temps est lié à la dimension des grains par la loi de Stokes; on en déduit la distribution de ces dimensions dans le sédiment étudié. 1, record 1, French, - m%C3%A9thode%20de%20l%27hydrom%C3%A8tre

"lacquer peel method".(...) "The oriented rock is polished with a grinding material to grain size 400 until there is a completely smooth surface. After thorough rinsing in water the polished surface is etched for 1 1/2 to 2 seconds in 33% diluted hydrochloric acid and then once more thoroughly rinsed in water.(...) The etched surface is now completely dried(...) and placed horizontally on plasticene with the polished surface up. As soon as the surface is more or less ’room dry’, acetone is carefully poured over the surface and continually squirted over the surface with a small pipette. The acetate sheet is immediately rolled on during this process.(...) The acetate sheet is pressed down with the finger and gently held down for about 5-10 minutes so that the peel can shrink. This shows itself in a slight waviness of the surface. The film is then carefully lifted off. 1, record 3, English, - lacquer%20peel%20method

"Technique des pellicules" La surface aplanie d'une roche est attaquée à l'acide chlorhydrique dilué pendant quelques minutes, lavée et séchée. Une empreinte en est prise au moyen d'une pellicule, dont il existe différentes formules. Le film, arraché de la roche, donne une réplique de la surface. Cette technique rapide et peu coûteuse donne parfois des résultats supérieurs à la plaque mince. 1, record 3, French, - technique%20des%20pellicules
