Estimations of the moisture and chloride content made on 

 this material yielded the following data: —

Additional experiments were then instituted, in order to 

 follow more closely the behaviour of intact tubers, differing in 

 type and degree of maturity, on steeping in brine solutions of 

 different concentration, to accumulate data similar to those 

 already amassed, and to e^xtend the investigations along lines 

 which might have certain practical applications. 



Experiment: — Two lots (5 each) mature thick-skinned Vic- 

 torian tubers, separately steeped in 10 per cent, and 15 per 

 cent, brines for eight days.
