DISEASES OF THE OX AND SHEEP. 337 



pointed out, they generally become enlarged and present on the 

 surface opaque patches which have been secreted by the glandular 

 follicles. In mild cases the soreness may be very slight and 

 speedily subside. Very often, however, sometimes at the begin- 

 ning, but more frequently in the second or third week, the 

 tonsils suppurate, ulcerate, or slough, or buboes and abscesses 

 form near them, or a false membrane appears on the surface 

 and extends to other neighbouring parts. 



During the febrile stage of the disease, the urine is scanty and 

 high coloured, contains a diminished quantity of chlorine, and, 

 according to Dr. Gee, not necessarily any increase of urea. 

 Subsequently it becomes more abundant and of lower specific 

 gravity. Albumen is often present in the urine, and its presence 

 is important. Many of the cases very severe in onset escape 

 albuminuria, while many of the mildest sufifer severely. Albumen 

 has been detected on the second or third day of the disease, but 

 more commonly in the course of the second or third week, during 

 the period of desquamation. The amount of it varies^ as also 

 does the time during which it persists. Not unfrequently the 

 urine is smoky, and when it is examined by the microscope, 

 hyaline and epithelial casts of the renal tubules are found, and 

 usually also blood-corpuscles, or casts containing altered blood. 



During the height of the disease, the skin is generally dry and 

 feels hot, and in malignant cases " petechise " often appear. The 

 temperature of the body attains a marked elevation very early 

 in scarlet fever. It often reaches 104 deg. or 105 deg. when 

 the eruption is fully developed, and very occasionally it rises to 

 even 110 deg. or 112 deg. It is unlike small-pox in that the 

 temperature rises instead of falling when the rash appears, and 

 unlike measles in that it subsides slowly after the rash has 

 reached its acme, instead of undergoing a sudden fall. 



The patient complains of soreness of throat, and has some 

 headache and giddiness, and general aching of the limbs ; but 

 the pains are not so severe as in many other febrile disorders. 

 In the beginning of the disease the patient is usually restless and 

 sleepless, and often a little delirious. When the eruption comes 

 out, and during the time of its persistence, the patient may still 

 be restless and excited, or dull and somewhat inclined to coma or 

 delirium. If the fever is of a very grave kind, violent delirium 

 may be one of the earliest symptoms. In children convulsions
