with a violent pleurisy the J 8th day, but was relieved by bleeding. The blood 

 was the most viscid he had ever seen. It is remarked by Lancisi, that people 

 expectorate very little in disorders of the breast, when cold, dry, easterly winds 

 blow ; and Dr. H. has frequently observed the same. And this may be one 

 reason, why some asthmatic persons generally suffer a paroxysm at such 

 seasons. 



The swelling of the hands did not so regularly succeed the detumescence of 

 the face, during this constitution, as in other epidemic small-pox. Some had 

 very small, or rather no tumours at all. It was very rare that the legs and feet 

 swelled, till after the patients sat up, and then they had much pain in the 

 parts. 



Perhaps the succession of the tumours of the hands, to those of the face, 

 might partly depend on the later inflammation and suppuration of the pustules 

 of those parts: the pain and inflammation being a stimulus determining the 

 humours to the pained part : and it is particularly to be observed, that the 

 greatest pain of the hands and arms commonly happens at the time when the 

 salivation begins to cease : so that the tumour of the hands may in some mea- 

 sure prove a succedaneum to the spitting. It is the common observation, that 

 the pustules of the arms and hands inflame and maturate a day or two later than 

 those of the face ; and those of the legs and feet latest ; which may also be the 

 reason that the tumour of the legs succeeds that of the hands. Dr. H. has 

 been the rather inclined to this opinion, as he sometimes observed a con- 

 siderable swelling of the hands, the pustules being very painful and inflamed, 

 and that too in the distinct kind, when there has been little or none in the face. 

 Generally the more painful a bile is, the greater the tumour around it ; and 

 consequently the tumour of a part is in proportion to the painfulness of the 

 biles, and their number. 



From this he would inforce the use of epispastics applied above the wrists, a 

 little before the time the tumour of the hands is expected to rise, especially 

 when symptoms are threatening, as they are stimuli to be depended on, not 

 only attenuating and deriving the humours to the parts, but also discharging 

 them, and so proving a convenient outlet to the morbific matter, which before 

 was thrown off" by the now partly suppressed salivation. 



Blisters applied to the neck frequently relieve the extreme pain of the throat, 

 and difficulty of swallowing, which are sometimes exceedhigly troublesome to 

 the patient in the third stage of the small-pox, by drawing the humours another 

 way. Nay, in some, where vesicatories have been early applied, and continued 

 to run extremely, there has been less swelling, and less salivation, than .seemed
