acceptable to the Reader. Belides, this is by no means 
a grateful Subjed 5 and it had been happy if no body 
had ever had occafion to write upon it. But fince it 
has pleafed God to afRid Mankind with this Diftemper, 
it is neceffary to advife and acquaint them with what 
Obfervation and Experience has demonftrated for their 
Good and Benefit. I have fome Thoughts of treating 
upon this Subjed more fully hereafter, if God grants 
me Life and Health : For we cannot obferve without 
Grief, that there is ftill an opportunity for farther Ob* 
fervations, by the Phgue's continuing to rage in the 
Neighbouring Countries with great Violence 3 and I 
doubt not but there are diligent and attentive Perfons 
there, who will communicate to me their Obfervations. 
Thofe that labour’d here with me the laft Year, will, I 
hope, do me the Favour to fumifh me with what Ob- 
fervations they made. I fhall my felf add feveral things 
now omitted, among which will be fome curious Ob- 
fervations, viz. How it happened that Womeu with 
Child, being infeded, came to be happily delivered, 
and the Child fafe and well, tho’ the Mother died : 
Again, how the Mother has been fafely delivered of a 
live Child, and yet both in a few Days fnatch’d away. 
How Nurfes and Women that gave Suck have been in- 
feded, and yet as long as they gave Suck perceived lit- 
tle of the Diftemper $ but upon the Child’s dying, have 
followed it in a few- Days after. Of thefe and fuch like 
Obfervations, I have carefully fetdown a great many. 
To the third Part of this third Memorial Ifhould have 
added, why Iffues (of the ferviceablenefs of which many 
Learned Men have given Angular Inltances) are reckon’d 
among the Prefervatives in the Plague 5 and whether 
Clyfters, which yet in the Cure are feldom or not at all 
mentioned, are of any ufe to the infeded. All which 
(ball, God willing, be explained and fully demonftra- 
tedy hereafter.
