IT. The Autobiography of Sir Samuel Mor land, in a letter addressed 

 to Archbishop Tenison. From the original manuscript preserved 

 in the library at Lambeth Palace. 



[MSS. Lambeth, 931, Grig.] 



SIR, I am not ignorant of the various reports of the excessive 

 prodigalities and other sins of my youthful daies, that have now for 

 a long time been spread abroad by the credulous and censorious 

 world ; especially since it has pleased Almighty God of late years, to 

 visit mee with manifold crosses and afflictions which have kept al-

 mortality, and knowing well that I address myself to a true Natha-

 give you an abbreviat of the history of some part and passages of 

 my life, being willing to carry the rest into the grave with mee, by 

 reason of the circumstances of the age wee live in, there to bee 

 buried in oblivion. 



Having received my education in Winchester Colledg, I was re- 

 moved to the University of Cambridg, where having spent nine or 

 ten years, I was sollicited by some freinds to take upon mee the 

 ministry, for which, fearing I was not fitly qualified, I betook myself 

 to the study of the mathematicks. Soon after, an occasion present- 

 ing itself, I accompanied an ambassador, (among several other gen- 

 tlemen) sent by the protector to the queen of Sweden. At my re- 

 turn, I was recommended to Secretary Thurlo for an assistant, and 

 in a few months time after, sent by Cromwell as an envoy to the 

 duke of Savoy in behalf of the protestants of the valleys of Pied- 

 mont. And from thence to Geneva, as his resident, to manage the 

 affayrs of those poor people together with other forraign ministers, 

 as likewise to transmitt the moneys collected in England for their
