Chap. XV. NOT BLENDING. 93 



either perfectly furnished with these organs or are quite destitute of them. 

 According to Kengger, the hairless condition of the Paraguay dog is either 

 perfectly or not at all transmitted to its mongrel offspring ; but I have seen 

 one partial exception in a dog of this parentage which had part of its skin 

 hairy, and part naked ; the parts being distinctly separated as in a piebald 

 animal. When Dorking fowls with five toes are crossed with other breeds, 

 the chickens often have five toes on one foot and four on the other. Some 

 crossed pigs raised by Sir E. Heron beet wen the solid-hoofed and common 

 pig had not all four feet in an intermediate condition, but two feet were 

 furnished with properly divided, and two with united hoofs. 



Analogous facts have been observed with plants : Major Trevor Clarke 

 crossed the little, glabrous-leaved, annual stock (Matthiola), with pollen of 

 a large, red-flowered, rough-leaved, biennial stock, called cocardeau by the 

 French, and the result was that half the seedlings had glabrous and the 

 other half rough leaves, but none had leaves in an intermediate state. That 

 the glabrous seedlings were the product of the rough-leaved variety, and not 

 accidentally of the mother-plant's own pollen, was shown by their tall and 

 strong habit of growth. 18 In the succeeding generations raised from the 

 rough-leaved crossed seedlings, some glabrous plants appeared, showing 

 that the glabrous character, though incapable of blending with and modi- 

 fying the rough leaves, was all the time latent in this family of plants. The 

 numerous plants formerly referred to, which I raised from reciprocal crosses 

 between the peloric and common Antirrhinum, offer a nearly parallel case ; 

 for in the first generation* all the plants resembled the common form, and 

 in the next generation, out of one hundred and thirty-seven plants, two 

 alone were in an intermediate condition, the others perfectly resembling 

 either the peloric or common form. Major Trevor Clarke also fertilised the 

 above-mentioned red-flowered stock with pollen from the purple Queen 

 stock, and about half the seedlings scarcely differed in habit, and not at all 

 in the red colour of the flower, from the mother-plant, the other half bearing 

 blossoms of a rich purple, closely like those of the paternal plant. Gartner 

 crossed many white and yellow-flowered species and varieties of Verbascum; 

 and these colours were never blended, but the offspring bore either pure 

 white or pure yellow blossoms; the former in the larger proportion. 10 

 Br. Herbert raised many seedlings, as he informed me, from Swedish 

 turnips crossed by two other varieties, and these never produced flowers 

 of an intermediate tint, but always like one of their parents. I fertilised 

 the purple sweet-pea (Lathyrus odoratus), which has a dark reddish-purple 

 standard-petal and violet-coloured wings and keel, with pollen of the painted- 

 lady sweet-pea, which has a pale cherry-coloured standard, and almost 

 White wings and keel; and from the same pod I twice raised plants per- 

 fectly resembling both sorts; the greater number resembling the father. 

 So perfect was the resemblance, that I should have thought there had
