    In these instances the variolous: eruption has | rarely been regular, being designated as small-pox disarmed, diminished, ae R : ° Characters of mitigated or modified ; the pocks few in number, and incrusta- the small-pox tion happening on the 5th or 6th day, without secondary fever. - Six of these correspondents have, however, stated that they have seen the disease taking the course of regular small-pox; three mention having seen a case or two that proved severe, and two state cases under their care were considered dangerous. In general no particulars are afforded ofthe previous vaccina- tion, except that it was deemed to have been suflicient; but a few represent these occurrences to have taken place, in those, whom they themselves vaccinated and attended during the progress of the cow-pox. In a severe case which Mr, Fulcher of Hingham met with, the patient had been vaccinated 20 years before, and stated ichor to have. been taken from a single vesicle to vaccinate others with. Mr. Barber of Hin- dolvestone represented the pocks, in two cases which he met with, to have been surrounded by a red circle; they had been formerly vaccinated by himself. The interval which elapsed between the vaccination: and: the occurrence of the variolous eruptions has commonly not been mentioned by my correspondents. The shortest interval Rai, specified is stated by a surgeon who vaccinated an infant which smalt pox has oc- three days old, and watched the cow-pox through its regular cured after progress, (during which the child was carried into a house where the small-pox was prevailing,) but three years after- wards it had the latter disease, which left scars, and fur- : nished matter for inoculating many others. The interval mentioned by 8 other surgeons is not less than five years, varying from that number to twenty. The mildness of many of these eruptions which are reported as small-pox after vaccination, has been the frequent cause of. dispute as to their nature, and the term that ought to be applied to them. In regard to their frequency, I have been
