INTRODUCTION. 
Indications of Cure, voluntarily flowed from the 
vtprbfick fate of the Sick , which proceeded i. 
from the Caufes Antecedent and Frcfcnt. 2. From 
the nature of the Difeafe, whither Similar , Orga- 
nic/:, or Common. 3. From the Symptoms., as be- 
ing Dangerous , or not. 4. From the Vital Powers, 
rejpethng the Strength or Weaknefs of the Dif- 
eafed Body. 
XI. ART BEING by thefe Advances , 
and Jo many Degrees , or Steps , brought on towards 
Perfeflion what remains for the Learned Pro- 
.feffor to do ? Truly to know what Difeafe it is 
which afflicts the P erf on, and by the Crifis, and 
manifejl Symptoms, to make his Medical Progno- 
Jiicks , whether the Patient be Curable or not that 
he may do every thing for the Reputation of his 
Arty and of himfelf So that if he fees the Sick 
paft hopes of Recovery, he may decline his At- 
tacks, and let the Relatives and Attendcnts know 
the Danger impending. But if there be Hopes of 
Life, (t ho' but [mail ) he may make his Artful and 
Mafierly Prefcriptions, according to the Indica- 
tions of Cure, which with a Rational and Modejl 
ajfurancc , he may hope and conclude, will not go 
without their dcfired Ejfefls. 
XII. LIKE ^15 THE Art of Rhetorick 
.was not ihe foundation of Oratory, or of the 
fir ft Orators , Demolthenes, Cicero, Lfc. but the 
Orators the foundation of the Art, out of whofc 
unexampled Oratipns, all its Precepts and Rules 
Black-Friers, London. 
mere Excerpted , or Gleaned , and by Wife Melt 
reduced into the form of an Art, by which all 
fucceeding Rhetoricians regulated and made their 
Orations : So the Medical Art , and all its Rules , 
even the Fabrick of the whole Art , mas Reared and 
Built out 0) Empiricifm, or Quackery ; and its 
Original or Foundation, was laid by Empiricks or 
Quacks, (as the Learned are p leafed to phrafe it) 
and that the firfi Phyficians were no other than 
Empiricks, Quacks, or Tryers of Skill ; out of 
whofe Trydls , Obfervations and Pratfifes, fame 
Wife Men colleLted a Set of Precepts and Ru'les ■ 
which being reduced into Method , we now call 
the Art of Phyjtck. But all the to be deplored 
Misfortunes of the. Art is, that it makes not a 
great many Real Phyficians, but too many Ignorant 
or Conceited Dollars, and too great a number of 
Formal and Rattle-headed Empiricks or Quacks. 
XIII. W H A T W E have farther to fay Is 
to commend the ftneere Lovers of Art , to the 
good Providence of God. That in their Search 
and Enquiries into Nature, and unravelling (as it 
were) the Rules and Precepts of Medicine, they 
may find the Anfwer of their ExpeSatwns\ and 
have their Minds or Souls, cnlightned with the 
Splendor and prevailing Excellencies , of true 
Wifdom and Knowledge fo as to be able to per- 
form the Great things , wrapt up in the My/leries 
of this Science they are Prof effort of-, for the 
Good of the Sick, their own Benefit and the Repu- 
tation of the ART of P H TS I C K.

I Requeft all thofe Gentlemen and others , who fend Letters to me , about their own 
Concerns, to be fo Civil, as to pay Portage for them ^ or elfe they may expert to go 
without an Anfwer. It is not reafonable that I (hould be at Charge for Perfons, I have no 
Acquaintance withall, and the Bufinefs their own. I (hould not fay this, was it but now 
and than a Letter. But to receive about two thoufand Letters a Year (as I have formerly 
done) upon other Peoples Affairs, or fome trifling Matter, and to pay Portage for them, 
makes a conliderable Sum. And befides, it is as Burthenfome and Troublefome to Aofwer 
hem, as it is Chargeable to Receive them.
