polariscopic

There follow a great number of precipitates; the exact volume of liquid in which these are found is determined after two polariscopic observations.

They consist in weighing out the sugar, dissolving it, clarifying the solution, making it up to standard volume, filtering, filling the observation tube, regulating the illumination, and making the polariscopic reading.

Scientific American Supplement No. 822, October 3, 1891

The polariscopic reading may now be taken, an observation on the 90° control plate having been made immediately before as previously described.

Scientific American Supplement No. 822, October 3, 1891

It would be very desirable to have an absolute standard set for polariscopic measurements, to which all instruments could be referred, and in the terms of which all such work could be stated.

Scientific American Supplement No. 822, October 3, 1891

Not only do the above polariscopic tests tend to this conclusion, but so does the following observation of mine in October.

Sugar drainings and sugar sweepings shall be subject to duty either as molasses or sugar, as the case may be, according to polariscopic test.

All sugars not above No. 13 Dutch standard in color shall pay duty on their polariscopic tests as follows, namely:

All sugars not above No. 13 Dutch standard in color, all tank bottoms, sirups of cane juice or of beet juice, melada, concentrated melada, concrete and concentrated molasses, testing by the polariscope not above 75°, seven-tenths of 1 cent per pound, and for every additional degree or fraction of a degree shown by the polariscopic test two-hundredths of 1 cent per pound additional.
