Tliis follows, as closely as might he expected, the numerical 

 results determined by Mendel. Regarding size in the case of peas, 

 it is not always easy to decide to which class a. wrinkled seed 

 belongs, and, again, the end peas in a pod frequently vary in size 

 from the others. It remains to be seen what the sizes in the plants 

 from -these peas will show as the standard and dwarf types are 

 brought together. 



At 5 is shown the seeds of a cross of the ''French Canner" (41) 

 uj^on the "Telephone" (30) and represented by the fraction 

 41/30. As in the last, the mother variety is one producing a 

 large, green, wrinkled pea, but, unlike the "American Wonder," 

 the "Telephone" is a standard sort. Only a few seeds were secured 

 in the fall crop of the first generation, but they show all the types 

 brought out in the scheme given for the last cross. 



The last cross, shown in the plate at 6, is that of a ])urple flow- 

 ered ]>lant growing in ?i mixed crop of peas and oats, "hand- 

 worked" upon "Horsford's Market" (19). Of the eighty-four 

 seeds secured, sixty-one were smooth and twenty-three wrinkled, 

 sixty-six gray and eighteen green, sixty-one large and twenty-three 

 small, which is a fairly close approximation in Mendelism. The 

 various types of seeds are shown in the watch glass at 6 with an 

 opened pod l)elow with smooth and wrinkled peas in place. 



There are several other crosses, not represented in the plate, 

 showing very striking differences in types of seeds borne upon the 

 same plant; that of "Nott's Excelsior" (21) upon the "French 

 Canner" (41) perhaps will afford a most interesting set of plants 

 in the next generation, as the contrasts of the parents arei, of 

 course, very great.
