[We are indebted to our valued correspondent JANUS DOUSA, for a transcript of the following important letter--the original of which is preserved in the Remonstrant Library of Amsterdam--and for which our correspondent acknowledges his obligations to the great kindness of Prof. des Amories van der Hoven.] "St. Giles's, in Dorset, Feb. 8-13. 1705. "Sir,--Having once writt to you in my own Language, I continue to use the same Privilege. I am sorry that I am in no better a condition to acquit my self of my Promise to you. My Recovery has been so slow, that I am scarce yet got up: and I have been unable to hold any Correspondance with my Friends in Town. Mr. King promisd to send me the Papers I mention'd to you of Mr. Lock's; who, it seems, had begun some Memoires of his own relating to my G^d Father. These however imperfect, yet as being Mr. Lock's own I should have been glad to send you with what supplement I could make myself: But Mr. King's Engagements in the Publick affaires has made him delay this so long, that according to the account you have given me of the shortness of your Time, I must wayt no longer: but content my self with giving you what I can out of my own head, without other Assistance. "Mr. Lock came into my Grandfathers Family in the summer of the year 1666, recommended by his Friend[1] Mr. Bennet of y^e town of Shaftesbury. The occasion of it was thus. My Grandfather had been ill for a great while after a Fall, by w^{ch} his Breast was so bruised that in time it came to an Imposthumation (?) within, and appeard by a swelling under his stomach. Mr. Lock was at that time a student in Physick at Oxford: and my Grandfather taking a journey that way to drink the Waters (having Mr. Bennett in y^e Coach with him), He had this young Physician presented to him: who tho' he had never practic'd Physick; yet appear'd to my Grandfather to be such a Genius that he valew'd him above all his other Physicians, the great men in practice of those times. Accordingly on his advice and allmost solely by his Direction my G^d Father underwent an Operation w^{ch} sav'd his Life, and was the most wonderfull of the kind that had been heard of, till that time. His Breast was layd open, the matter discharg'd, and an Orifice ever afterwards kept open by a silver pipe: an Instrument famouse {98} upon Record, in the Writings our Popish and Jacobite Authors, who never faild to reproach him with this Infirmity.
