DISEASES OF THE OX AND SHEEP. 333 



The pulse may be about 120 in the case of an adult, about 

 160 in that of a child, and the temperature may be nearly 105° F. 

 during the first day. The patient may be delirious, or may even 

 exhibit a tendency to coma. 



On the second day the rash may make its appearance on the 

 chest, fore-arms, lower part of the abdomen, and upper part of 

 the thighs, and at about the middle of the third day it reaches 

 its greatest intensity. At first it consists of very minute rosy 

 spots or papules which may possibly be due to the conical 

 elevation of the cutis around the points wherefrom the individual 

 hairs emerge. These spots afterwards enlarge and become 

 more red, and they may blend in some degree so as to impart 

 to the skin a uniform scarlet hue, although if the skin be 

 closely inspected the papular character of the rash can still be 

 observed. The spots situated on the chest and neck may not 

 unfrequently become vesicular. The rash is usually attended 

 wiih more or less infiltration and thickening of the cutis. It 

 may be the case, though very rarely, and either when the rash 

 is at its height, or at the beginning of its decline, that a serous 

 fluid is extensively poured out beneath the epidermis, especially 

 that of the trunk, so that the surface becomes covered with 

 small flat blebs which tend to become continuous. This con- 

 dition necessarily leads to a larger and coarser desquamation 

 than usually occurs. If the skin be pressed, as, for example, 

 by drawing the edge of the nail firmly over it, the vivid 

 redness of the skin disappears for a second or two. The rash 

 varies greatly both in regard to its intensity and to its diffusion, 

 and it may be limited to the parts in which it first appears. 

 The rash is often especially marked on the neck, chest, 

 abdomen, and inner aspects of the thighs and arms. The feet 

 and hands may not uncommonly be stiff with it, and the 

 oedema which attends it. 



The rashes of the specific fevers sometimes illustrate the 

 similar origin of the parts which they affect. For instance, the 

 rash of the fever we are now considering, namely, scarlet fever,., 

 may occur in many parts of the body which have been developed 

 from the epiblast. It may occur on any part of the skin, 

 and is only rarely distinctly marked on the face, although 

 there are frequently irregular patches of redness on it. How- 

 ever, the rash may be only seen on the face with some diflSculty,.
