feithnet

The same as FEETH (q. v.). "The largest feith - net is six fathoms long, two fathoms deep at the river end, and one fathom at the land end." State , Leslie of Powis , ., p. 109. feet-le , a. [Eng. feet; -le .) Destitute or deprived of feet; footle . "There behold the mangled, headle , feetle corpses of their fellow-countrymen."-Fuller. Holy War , p. 196. of Chem.: A solution used to determine the amount of glucose in a solution. It is prepared by di olving in 200 cubic cent. of distilled water, 34.64 grammes of pure crystallized cupric sulphate, pre paper, and mixing it with 174 grammes of Rochelle salt di olved in 400 c. c. of a solution of pure caustic soda. Specific gravity, 1'14, the volume being made up to 1 liter. Each c. c. of the solution represents 5 mille grammes of anhydrous grape sugar, 7'46 mille grammes of milk sugar, '03464 gramme o cupric sulphate and "01103 gramme of CuO. The liquid must be kept in bottles protected from the light, and from absorption of CO2 from the air. A known volume of the Fehling's solution, 10 c. c. of solution and 40 c. c. of water, is placed in a white porcelain dish, heated to boiling, and a diluted solution of liquid to be examined is run in from a bu rette till the whole of the copper is separated as suboxide, as shown from the absence of blue color. Starch can be converted into glucose by boiling with dilute sulphuric acid 100 parts of grape sugar =90 of starch, therefore each c. c. of Fehling's solution equals 4.5 mille grammes of starch.
