 also be most fully enabled to ^^ive a reason for your 

 jutlfrement to him that askcth you. Hereby you 

 .see what reason may be given for medicines, and 

 also what great necessity there is for every phy- 

 sician to be an astrol(\gian. Notliing now remains 

 but that you daii}' labour to glorify God, and see 

 that you also duly answer the great e/)d of your 

 creation, in your several stations and situations in 

 life, and do good to yourselves first, by daily in- 

 creasing your knowledge; and afterwards by heal- 

 ing the sickness and bodil}- infirmities of your neigh- 

 bours. Some such characters as these, I hope are now 

 to be found in this nation ; to such shall 1 remain a 

 Friend, and that you may all receive much bene- 

 fit from my work, is the sincere wish of j'our ever
