-We promised last month (ogive a description of the common lactometer, or instrument for testing the qaality of milk, and ascertatning the proportion which the oream bears to the milk of any particular cow or the produce of a whole dairy This instrument is represcated above. It consists of a m h )g any frnme, 10 inches long, 4 wide. and 3 high, in which stand six glnss tubes. in a manner resembllng candle moulds These tubes are about II inches long, atid halfan inch in diameter inside. Just 10 nches from the bottom a fine line is marked round the tubes with the point of a diamond, and from this mark three inches down ards is gradualed into inches and tenths of incbes. At milkin these tubes are filien! oxactly to the upper line, (om from each cow,) and af ter 6tandina; twelve hours, the quantity of creom which has risen to the surface is shown by the degrees of ihe sca'e: each degree representing- one per cent. of the whole. Thus, if thsre fihould nppear 1 inch and 2 tenths, it would be 12 degreee; or the milk would give 12 per cent of cream.The expense of a Urge body of elephants, as was formeiy the practice in India, for war or ceremony, must have been ex cessive.
