falutary eruptions appeared, but in the latter were, 
as he juftly apprehends, checked by the exceffive 
cold weather ; and fhould it appear, that by inocu- 
lation the fame regular eruptive fever has been pro- 
duced, with every llage, and the fame fymptoms as 
arile in the fmall-pox ; the nature of this diftemper 
will then be afcertained. 
I (hall now proceed, my Lord, to lay before your 
Lordfhip and the Society the accounts I have received 
relating to the infedion and inoculation of the cattle, 
and make fome obfervations on the experiments made 
at Iffurtille. 
So long, my Lord, as the diftemper has raged in 
Great Britain, not one attefted proof has been brought 
of any bead having this difeafe regularly more than 
once. I make no doubt but thefe creatures may be 
liable to eruptions of different kinds; but as all forts 
of eruptions, fays Dr. Mead (6), are not the fmall- 
pox, nor meafles, fo every puftule is not a fign of 
the plague. Thro’ ignorance, or fraud, perfons may 
have been deceived in purchafing cattle, and have loft 
them, as well in England as in the provinces of 
France mentioned by the Marquis ; but until a fe- 
cond infedion be proved, the general opinion muft 
prevail in this cafe, as in the fmall-pox: for tho' 
many have infilled on the fame thing with regard to 
the fmall-pox, yet a fingle inftanCe, properly vouched 
and attefted, has never been produced, either after 
recovery from the natural way, or from inoculation ; 
unlefs what is frequently the cafe with nurfes and 
others attending the fmall-pox, that is, puftules
