 method for the quantitative determination of pectin is given. Ten cc. of filtered juice 

 is added drop by drop from a pipette, with vigorous stirring, to 180 cc. of alcohol. The solu- 

 tion is filtered, immediately dissolved in boiling distilled water, evaporated to dryness, heated 

 two hours at 70°C. in vacuo, weighed, burnt to ash, and reweighed. The loss in weight 

 multiplied by ten gives the percentage of pectin in the juice. — Henry Schmitz.
