THOHKR. [To,,,M-s] 

 THORESBY, RALl'H (born 1888, died 1725), a virtuoso 



It cunt 

 origin 



no 



and antiquary, ami an early Fellow of Ihe Royal Society. 

 was the son of a merchant at Leeds, and born in that town. 

 He hail his early education iU grammar-school, 



but, lieinir intended hv .it life, lie 



did not pass to any ol the lii.:h II 



had however what m.n a liljeral eommeieial edu- 



iter to Holland lor the pu 



of becoming acquainted with the mode of conducting I>UM- 



.ilrv. and of ac(|uirini; the modern lan- 



,s to London lor a similar pin; 

 "led in his native town, where his i. 



nected with some of the principal persons who titeit formed 

 the society . id wheie he hail a busiin ss | ir , j. 



for him, winch had I his 



lather, vvlto died when the son was ji. 



Thoresby possessed fioiii a Tery early pi-nod of In 

 ea^er curiosity respecting the things and , ound 



him which presented any lealures of historical interest, and 

 a desire of collecting ubjeels ol c niioMtv, natttial or artifi- 

 cial. His father bad soinethinit of th ivin? 

 pureha-sed the collection of coins and medals which had 

 Been formed by the family of Lord Kairtax, the parlia- 

 mentary general, and this collection : the 

 miiseiim formed in a lew \eais by the son 

 \\as a means of bringing him acquainted with all the 

 biated antiiniarie.s and naturalisi.s of the time, and wan a 

 perpetual attraction to persons of curiosity, who oftvn 

 visited Leeds for no other purpose than to see it. It is not 

 too much to say of it that it was perhaps the best museum 

 ever lornied in KnirUuul by a gentlemen of private and 

 rather small fortune: contaminj. il "ine things 

 which would now be esteemed of not the smallest v 

 but also many object!, of very hi^h value, especi- 

 ally in the two grand departments of manuscripts and 

 coins. 



As lie advanced in life, the curiosity which had at first 

 been directed upon the objects more immediately around 

 him became expanded so as to comprehend objci 

 suore general interest, and in fact the whin what. 



is usually understood to be comprehended in the term an- 

 tiquarian literature. In the department of natural history 

 he was also not merely a collector, but an observer, and he 

 made many communication!, esteemed of value, to Ills 

 private friends or to the Royal Si . 



With this turn of mind, it will hardly be supposed that 

 he was very .successful in his mercantile affairs. He had 

 however the good sense In withdiaw houi 



:mie was entire!) lost to him, and about Ihe 



sixth year of his ms to have wliollv letned from 



it, and to have formed the determination of living on the 



little income which the portion of his propeitj that re- 



1 would afford him. 



Besides ain.i"in_' Mich manuscript matter as he eouJd by 

 any means become possessed of, lie wax himself a labo- 

 rious transcriber, ami accustomed to commit to 

 vvi;tiiiLT notes of things which he observed, or information 

 eollectid liom his iriciid-. or the old people of Ins time. 



U'hei: com the can new, he had leuura to 



il he entered upon the prepaia- 



tion for the piess of two vvoiks. which It w;i.s intended by 

 him should contain all that he had gathered in what hud 

 been from the first his iavourite subject, the illustration of 

 the history, and whatever belonged to it, of his nativetown. 

 One of them was to be in the form of a topographical 

 survey of the whole of the laryc parish ol LIMN, and of 

 a few of the smaller parishes which are supposed to have 

 been comprehended under the \eiy anlient local term 

 Khnete:' t he other, a history of the various transactions 

 of which that district had been the id more enn
