II. 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, Orig.] 



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

 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
