MDCCXLVI. In this condition the ulcers often continue 

 lor a long time ; while new tumours, with ulcers succeeding 

 them in the manner above described, make their appearance in 

 different parts of the body. Of the first ulcers, however, some 

 heal up, while other tumours and ulcers appear in their vicinity, 

 or in other parts of the body : and in this manner the disease 

 proceeds, some of the ulcers healing up, at least to a certain 

 degree, in the course of summer, and breaking out in the suc- 

 ceeding spring : or it continues, by new tumours and ulcers 

 succeeding them, in the spring season, making their appearance 

 successively for several years. 



MDCCXLVII. In this way the disease goes on for several 

 years ; but very commonly in four or five years it is spontane- 

 ously cured, the former ulcers being healed up, and no new 

 tumours appearing : and thus at length the disease ceases en- 

 tirely, leaving only some indelible eschars, pale and smooth, 

 but in some parts shrivelled ; or, where it had occupied the 

 joints, leaving the motion of these impaired, or entirely des- 

 troyed. 



MDCCXLVIII. Such is the most favourable course of this 

 disease; and with us it is more frequently such than other- 

 wise ; but it is often a more violent, and sometimes a fatal mal- 

 ady. In these cases, more parts of the body are at the same 

 time affected ; the ulcers also seeming to be imbued with a pe- 

 culiarly sharp acrimony, and therefore becoming more deep, 

 eroding, spreading, as well as seldomer healing up. In such 

 cases, the eyes are often particularly affected. The edges of 

 the eyelids are affected with tumour and superficial ulcerations; 

 and these commonly excite obstinate inflammation in the adnata, 

 which frequently produces an opacity of the cornea. 



When the scrofula especially affects the joints, it sometimes- 

 produces there considerable tumours ; in the abscesses follow- 

 ing which, the ligaments and cartilages are eroded, and the ad- 

 joining bones are affected with a caries of a peculiar kind. In 

 these cases, also, of more violent scrofula, while every year 

 produces a number of new tumours and ulcers, their acrimony 

 seems at length to taint the whole fluids of the body, occasion- 

 ing various disorders ; and particularly a hectic fever, with all
