the content and distribution of the hydrocyanic acid are also 

 given. Finally, a comparison of the starch and hydrocyanic 

 acid found is compared with that previously recorded for 1903. 

 This work, as that in table IV, is mainly that of Mr. F. N. Thomp- 

 son of the Laboratory staff. Table IV gives the distribution of 

 the total hydrocyanic acid as between the cortex and the inte- 

 rior. The percentage of the total found in the cortex is also given 

 in view of Carmody's Rule previously referred to. Table V sum- 

 marises the majority's opinion upon the edible qualities of the 

 series of varieties.
