1818.] the Rev. W. Gregor. 113 



Here he finally fixed his residence, performing with exemplary- 

 attention his various duties as a christian pastor and a magis- 

 trate; holding in difficult and doubtful times the even and 

 conscientious tenor of his way, dispensing to his neighbours both 

 spiritual and temporal benefits, and enlivening the society of his 

 friends by his cheerful and instructive conversation. The latter 

 years of his life, embittered as they were by bodily suffering, 

 only afforded him a more favourable opportunity of practising the 

 precepts which he taught, and of experiencing, personally, the 

 vital and consoling energy of those hopes and of those truths, the 

 enforcement and exposition of which had constituted his most 

 momentous and delightful employment. He died at Creed, on 

 June 11, 1817, carrying with him the regrets of his friends, and 

 the respect of the entire county. 



A detail of his professional publications, consisting of sermons 

 preached on particular occasions, and an address to a member 

 of the House of Commons on the subject of the non-residence 

 bill, is omitted in the present brief notice, the object of which 

 is only to exhibit the claims of Mr. Gregor to be remembered as 

 a man of science. 



In the year 1791 he communicated to the Journal de Physique 

 an analysis of a black sand found in the parish of Menaccan, 

 about six miles south of Falmouth. This substance he found to 

 contain nearly half its weight of a metallic oxide as yet unknown 

 to chemists, and to which Klaproth, in the elaborate essay which 

 he published some years afterwards on this and other ores of 

 the same metal, gave the name of titanium. 



In the Philosophical Transactions for 1805 is a paper by Mr. 

 Gregor, in which he shows that a mineral found at Stenna Gwyn, 

 in Cornwall, and which had been supposed to be a variety of 

 zeolite, is, in reality, a hydrate of alumine, not differing in any 

 essential particular from the wavellite of Barnstaple, which had, 

 just about that time, been analyzed by Sir H. Davy. The same 

 paper also contains an interesting examination of the uranite 

 found in the same mine with the preceding mineral. 



In 1809 he communicated to the Royal Society his discovery 

 and analysis of native arseniate of lead, also found in Cornwall. 



The Geological Society gladly enrolled him among its hono- 

 rary members ; and in the third volume of the Transactions of 

 that body is a description and analysis of the tremolite, which had 

 been recently found in the serpentine of Clicker-Tor, near 

 Liskeard. 



When the establishment of a Geological Society in Cornwall 

 was agitated, Mr. Gregor engaged warmly in support of the 

 measure, and contributed essentially to its success. In return 

 for these and other services, and partaking in the general regret 

 occasioned by the loss of this excellent man, Dr. Paris, then 

 Secretary to the Koval Geological Society of Cornwall, delivered
