Saluki and there is a more pronounced depression at the 

 nasion. The teeth are strong and well developed as in the 

 Saluki, but the mandible is slightly prognathous with the 

 lower incisors fitting in front of the upper, giving somewhat 

 disturbed dental occlusion. 



The Saluki is of normal size while the Pekingese is a dwarf, 

 as is clearly shown by figures 1 to 4 in plate 34. The height 

 of the Saluki at the withers is about two and a half times that 

 of the Pekingese. The F x hybrid, with its short legs, is only 

 half as tall as the Saluki, but it is large and strong in body 

 and weighs about as much as the Saluki and three times 

 as much as the Pekingese. The two F x hybrids shown in 

 plate 34 are closely alike in all their measurements and 

 features with the exception of coat color, and this was mixed 

 in the Saluki ancestry. The length and texture of coat is 

 intermediate, being heavier and more uniform than in the 

 Saluki and not so feathery as in the Pekingese. In disposi- 

 tion the F! is very active and playful. It also lacks both the 

 elegance of posture of the Saluki and the haughty arrogance 

 of the Pekingese. 



The pair of F x hybrids just described produced four litters 

 of six, four, five and two puppies. Eight of these seventeen 

 Fo offspring survived to adult age ; nine were studied only as 

 young and immature animals. Plate 75 shows the eight adult 

 Fo hybrids, and plate 73 (figs. 5-12) shows profile views of 

 the same animals arranged in a similar order. 



None of these dogs carries the tail curled over the rump, 

 as does the Pekingese, but several carry it as a high open 

 circle over the back in Saluki fashion. No. 2111 $ (fig. 12,
