(See below " ;) The principle of the lactobutyrometer is based upon the obser- vation, that alcohol separates from milk which has been mixed with ether, an etheric fat solution, the volume of which stands in an intimate relation to the quantity of fat dissolved in the ether. The method and apparatus were invented by Marchand, and the latter was called by him the lactobutyrometer. The lactobutyrometer is a tube of equal width throughout (10 to 12 ), closed at one end. From this point on the lacto- butyrometer is divided into three equal parts, each being 10 or 5 A space equal to about 1 of these parts must remain to allow the contents to be well mixed by shaking. The space be- tween the two upper marks is subdivided into ts While the lactobutyrometer may he used by the inspectors, its results should always he verified hy actual analysis, when a case is to he brought before the courts. 7«.
