Fecundity

(fe-kun’ ’-dit-e) [fecund it as, fruitfulne ]. The ability to produce offspring. Fehling’s Solution. A solution used as a test for glucose, especially in the urine. The solution is prepared as follows: (a) Copper sulphate, 34.652 grams, is di olved in about 200 c.c. of water. (b) Sodic pota ium tartrate (Rochelle salt), 173 grams, is di olved in 480 c.c. of sodium hydrate solution of specific gravity 1. 14. The two solutions are mixed and sufficient water added to make 1000 c.c. One c.c. of this solution is reduced by 0.005 of glucose. To apply the test, a small quantity of the solution is placed in a test-tube, diluted with water, boiled, and the urine added drop by drop. The presence of sugar is indicated by a reddish or yellow precipitate, due to the reduction of the copper sulphate to the copper oxid or hydrate. 274
