dons of the Lupin (fig. 4) are united 
along their bases, and a marked difierence 
is observable between the cotyledons and 
the leaves which immediately succeed 
them. Seedlings of the Furze (fig. 6) 
may be found in quantities on poor heaths 
in early summer, especially where furze 
has been burnt in the previous autumn. 
In Silverweed (fig. 8), an abundant yellow- 
flowered wayside weed belonging to the 
Rose family, there is a wide diflTerence 
between the cotyledons and the ordinary 
foliage leaves. In Daisy (fig. 9), on the 
other hand, the diflFerence is much less 
marked. Seedlings of Beech (fig. 3) 
spring up in numbers in beech planta- 
tions and copses. In Yew (fig. 10) there 
is a close resemblance between the 
cotyledons and the subsequent leaves. 
By the publication of this work Sir 
John Lubbock has opened up a new 
field of inquiry, and one which can hardly 
fail to be profitably pursued by cultiva- 
tors of plants. Such practical questions 
as the depth of sowing, the character of 
the seed bed, the quantity of seed per 
acre, and the treatment of seedling 
plants may all be studied in a new light 
when it is appreciated how very greatly 
seedlings differ from each other. As, moreover, the study is not
