The result sliows that practically no hydi-olysis had taken 4)lace in 

 twenty-three days. The flasks at the end of this time remained sterile. 



COCONUT MEAT WITH HYDROCHLORIC ACID. 



( b ) Oue hundred grams of meat from a nut with a sprout about 75 centi- 

 meters long were thoroughly ground with 2 grams of chloral hydrate and 50 cubic 



centimeters of _ hydrochloric acid; 10-gram samples of the mixture were placed

 in small, stoppered Erlenmeyer flasks and titrated with — potassium hydroxide 



after the addition of absolute alcohol and phenolphthalei'n. The result was as

The flasks were laractieally sterile at the end of twenty-two days. The 

 slight apparent increase in acidity may almost he accounted for by 

 experimental error, as in a non-homogeneous mixture such as this an 

 exact titration is exceedingly difficult. 



EXPRESSED LIQUOR FROM FOOT AND MEAT OF A SPROUTING NUT IN EMULSION WITH 

 COCONUT OIL AND GUM ACACIA. 



Experiment VIII. — One hundred grams of foot from a sprouting nut, 100 of 

 meat from the same nut, 100 of sand and 100 cubic centimeters of a 2 per cent 

 chloral hydrate solution were ground together in a mortar for two hours and 

 the whole mass expressed; there resulted a muddy liquor consisting of water and 

 partially emulsified oil. Fifty grams of coconut oil were rubbed up with 20 

 grams of gum aca«ia and 100 grams of this press liquor to form a permanent 

 emulsion, 10 cubic centimeter samples of which were transferred to flasks and
