departments of the reign of nature. In external form,, hues, 

 and clothing, there is quite sufficient of general likeness betwixt 

 plants and insects to stamp them as productions of the same 

 designing mind and matchless skill. In clothing, wool, hair, 

 spines, and scales are common to both. Flowers alone emulate 

 the colours of the more splendid butterflies and beetles. The 

 delicate veined leaflet or petal are prevailing similitudes of 

 form drawn yet closer in the papilionaceous tribe; the purple 

 pea- flower and the yellow broom telling us, in poetic per-

A general analogy of internal structure is well known to 

 prevail throughout the animal and vegetable kingdoms; but 

 of this correspondence there is perhaps no particular instance so 

 close and striking as that which has been noticed between the 

 origin and development of lepidopterous insects (moths and 

 butterflies) and those of perfect plants. The egg and the 

 seed the caterpillar and the bud the expanded insect and 

 the expanded flower arc correspondences not fanciful but 

 existent ; and, as a flower in its rudiments can be discerned 

 within the bud, where, protected by successive leaf-scales, it 

 sometimes remains throughout the winter,"* so the future 

 butterfly lies enfolded within the numerous successive skins of

 Du Hamel, quoted in " Insect Transformations," p. 136.
