shown ill the acc()ni])aiiying data. All instances in which fruit was 

 lost, as described above, are noted in Table III. 



Table IV shows the different forms of most frequent occurrence 

 which were classed as variable fruits, and the total number of each 

 form recorded from each of the trees listed in Table III during the 

 iiiA^estigational period. It will be noted that the large number of 

 fruits of the Lisbon strain listed as collared, protruding blossom end, 

 and ridged vary but slightly from the typical fruit of the variety 

 and are continuous variations or fluctuations, probably caused to 

 some extent by certain climatic conditions. These fluctuations 

 are encountered in all the strains of this variety. A similar condition 

 was found in the Eureka variety.
