Showing for the same times of day, the ;age weights of the same skein of yarn, the;age humidity and average temperature for tenobservations a day for a period of nearly oneyear. Humidity observations not recorded for ashort time, and this period is not included onthis oil upon the net result,* a quantity of 2/24 soft twist, Frenchspun, fine Australian yarn was prepared and extracted withether, dried and extracted again with warm water, to whicha few drops of ammonia had been added. After being allowedto remain hung up for some time, to come to its naturalstate, this yarn was made up i»to groups of skeins of thesame length each, and of approximately the same weight. Thefinal weight and moisture state of these skeins was carefullydetermined after being hung up together again for a period ofabout two days. The moisture state was determined by testingindividual skeins of the different groups, by drying in theordinary Bradford oven at a temperature of from 220 degreesto 230 degrees until they ceased to lose weight, and also byleaving small two gramme skeins in a weighing bottle, undera dessicator, and over strong sulphuric acid. These twomethods were used to check each other from time to timeduring the exp
