Experiments refpeEling the Vacctne Dlfea/g. 315 



be diftinguifhed from thofe of tliefmall-pox, and which were 

 wholly unexpeded from the orighial defcription by Dr. Jen- 

 ner. No explanation hitherto given confills with the ob- 

 iervations relative to thefe eruptive cafes : but the fads are 

 as Dr. Woodville dates (Med. Mag.), that they have oc- 

 curred much lefs frequently this fummer than in the fpring 

 and winter preceding. In my private practice, not a fingle 

 cafe with eruptions rcfembling the fmall-pox has occurred 

 thefe laft four months, and but a fmall proportion with any 

 eruptions of other kinds. From my correfpondents I have 

 not had a fmglc cafe of eruptions like the variolous fince that 

 of Dr. Redfearne's of Lynn ; not one of this forj; in Mr. Kel- 

 fon's, of Seven Oaks, report of about 100 patients j not one 

 in Dr. Mitchell's, of Chatham, of about 50 patients ; not 

 one in the report of near 100 patients from Dr. Harrifon of 

 liorncaiile, connnunicatcd to the Rt. Hon. Sir Jofeph 

 Banks ; and, in fliort, not one cafe with thefe eruptions ap- 

 pears in the accounts from my other correfpondents. 



4. The arms have manifefted, in many indances, a much 

 more cxtenfively fpreading red areola around the laocuLited. 

 part than is ufual in the fmall-pox ; which rcdneis fomc- 

 timcs extended over the greater part of the whole arm. This 

 appearance is very alarming to both the patient and the in-» 

 fxpericnccd practitioner ; but no danger fcems to be attend- 

 ant on fuch a Hate of the parts, for it difappcars in at mofi; 

 iwo or three days, by no means gives pain in proportion to 

 its appearance, and, in the cafes I have foen, affefts the 

 conftitution very little. I would rather call this fpreading 

 rednefs of the (kin erythema than eryfipelas. As to phage- 

 denic ulcers, as they have been called, enfuing from the 

 inoculated part, nianv fore arms have beeni produced ; but 

 nine out of ten were occafioncd, or at lead much aggravated, 

 by the lightnefs of the clothes ; by allowing the linen to flick 

 to the fore; by fcratchiug llie pullulc ; and fometimcs by emol- 

 lient poultices. The experience we have iiad, then, fince .Ta- 

 liuiirv )a(t, iu Loudon and in the country, does not agree ex-
