This section treats of the velocity-reaction curves 

 of the Btarches of Lilium tenuifolium, I., 

 album, and /.. gold <. showing the quantitative 



differences in the behavior toward different n 

 definite time-intervals. (Charts I' 36] to D 366.) 



These Btarches generally read so rapidly with 

 various reagents thai there are few instances where the 

 data arc of value in presentation in the form of cl 

 Tn tlic reactions with nitric acid, sulphuric acid, hy- 

 drochloric acid, potassium hydroxide, potassium iodide, 



ami sulphocyanat sium Bulphide, sodium 



hydroxide, and -odium sulphide complete or nearly com- 



gelatinization occurs of all three starches within 

 ids. In other reactions, notwithstanding 

 the rapidity, more or less differentiation is evident, as 

 with calcium nitrate, uranium nitrate, strontium nitrate, 

 cobalt nitrate, copper nitrate, cupric chloride, and mer- 

 curic chloride, in which gelatinization is almost if not 

 wholly completed in 3 minutes. Differences in these 



are quite noticeable at the end of f minui 

 tenuifolium has a lover reactivity than the other parent 

 in the calcium-nitral eupric-chloride reactions, and 



a higher reactivity in tl -. and the hybrid - 



vitiee as high or higher than cither parent. Not 

 much importance is to be attached to these figures, al- 

 though they arc very suggestive, owing to the difficulties 

 of obtaining accurate' records. Referring to the chart-.
