40 THE PENYCUIK EXPERIMENTS. 



mustard. Though he kicked aimlessly when pinched, he 

 paid no heed to the application of either warm or very 

 cold substances to the skin. When a dog was first intro- 

 duced to Romulus, his excitement was intense. He rushed 

 about at a furious rate, striking as opportunity offered 

 Avith his fore-feet, holding his head high and stepping 

 high, as if moving through long grass, where other enemies 

 might lie concealed. Remus, on the other hand, when 

 two days old, allowed a yellow collie to lie down within 

 six inches of his muzzle, and only got up as a Dalmatian 

 approached, when a warning note was uttered by his 

 Avatchful parent. When the four 1897 hybrids and two 

 pure-bred foals were eventually weaned, Remus seemed to 

 mind very little. While one of the hybrids and a half 

 Arab foal were biting and kicking and rushing about as if 

 demented, Remus simply stood looking over the fence. 

 But by-and-by, when the others settled down, he set to 

 walking backwards and forwards behind the wall of his 

 court, exactly like his zebra sire, and though he still 

 keeps this up as if he were a caged lion, none of the 

 others have followed his example. When Romulus was 

 weaned, he for some days rushed about, as much like a 

 zebra v/hen highly excited, as his sire when upset by the 

 beating of carpets. Recently it was necessary to give the 

 hybrids milk containing thymol. The pure-bred foals 

 offered but little resistance, but all the hybrids fought till 

 they were exhausted, and nothing would persuade Remus 

 to swallow the first dose. 



As might have been expected, Biddy's foal is much 

 lighter in colour than Mulatto's. With the exception of 

 the muzzle and the lower part of the legs, the body colour 

 is a rich light bay; the muzzle and legs were, at birth, 

 more of a mealy colour, but are now of a bay colour. The 

 bands are much lighter, and consequently less distinct 

 than in Romulus. As a rule they are of a dark reddish 

 hue, being especially evident on the brow, the forearms, 

 and above and below the hocks. The plan of the striping 

 is the same as in Romulus ; but even at birth several of the
