mentioned, to have appeared in many countries in which it had 

 never appeared before. 



" Among the uncertain accounts which we have in authors 

 on this subject, nothing has been more common than their con- 

 founding the miliary eruptions with the petechiae ; and they 

 have all been called by the common name of Purpura. There 

 is some sort of foundation for maintaining the connexion, as 

 the same kind of putrid fever is sometimes attended with the 

 one, and sometimes with the other eruption ; but the proper 

 petechiae are always much more expressive of putrefaction than 

 the miliaria." 



DCCXV. From the time of its having been first particu- 

 larly observed, it has been described and treated of by many 

 different writers ; and by all of them, till very lately, has been 

 considered as a peculiar idiopathic disease. 



It is said to have been constantly attended with peculiar 

 symptoms. It comes on with a cold stage, which is often con- 

 siderable. The hot stage, which succeeds, is attended with 

 great anxiety, and frequent sighing. The heat of the body be- 

 comes great, and soon produces profuse sweating ; preceded, 

 however, by a sense of pricking, as of pin-points, in the skin ; 

 and the sweat is of a peculiarly rank and disagreeable odour. 

 The eruption appears sooner or later in different persons, but at 

 no determined period of the disease. It seldom or never appears 

 on the face ; but discovers itself first upon the neck and breast, 

 and from thence often spreads over the whole body. 



DCCXVI. The eruption named Miliary is said to be of two 

 kinds, the one named the Red, the other the White Miliary. 

 The former, which in English is strictly named a Rash, is com- 

 monly allowed to be a symptomatic affection ; and as the latter 

 is the only one that has any pretensions to be considered as an 

 idiopathic disease, it is this alone that I shall more particularly 

 describe and treat of in the present chapter. 



DCCXVII. What then is called the White Miliary erup- 

 tion, appears at first like the red, in very small red pimples, 

 for the most part distinct, but sometimes clustered together. 

 Their slight prominence is distinguished better by the finger 

 than by the eye. Soon after the appearance of this eruption, 

 and at least on the second day, a small vesicle appears upon
