fruits of the same travels, he disposed of to the late Mr. Payne 

 Knight, in the course of the next year, 1810. On both these 

 occasions Dr. Clarke displayed great liberality during the nego- 

 ciation, with much anxiety for the ulterior use and destination 

 of the collections. Early in the year last mentioned, the first 

 volume of his 'Travels' appeared, the second in 1812, the 

 third in 1814, the fourth in 1816, the fifth in 1819 : of the sixth 

 only twelve chanters were finished at his death ; the rest were 

 added by his friend the Rev. Robert WalpOle, to whom the pub- 

 lic are indebted for many interesting and valuable notes in the 

 former volnmes. 



The year 1817 opened with a most flattering testimony ot the 

 esteem' in which he was held in the University, by his election 

 to the office of Sub-Librarian, vacant by the death of Mr. 

 Davies, and the promotion of Mr. Kerrich to that of Principal 

 Librarian. His attention during this year was principally occu- 

 pied by his experiments with the * Gas Blowpipe,' most of 

 which he described in tire Annals* In the same year he con- 

 tributed two papers to the Society of Antiquaries, and one to 

 the Geological Society ; all which have been noticed in the 

 Annals: (vol. ix. p. 395, and N. S. vol. vii. p. 73). In 1819 

 he collected his experiments with the 'Gas Blowpipe' into 

 a small octavo volume, which was published under that title, 

 with engravings of the instrument, the safety apparatus, &c. 

 This year also produced his Dissertation on the Lituus, read 

 before the Antiquarian Society in 1820, and published in the 

 Archseologia for i 821. 



Dr. C. was one of the most zealous founders of the Philo- 

 sophical Society of Cambridge, and drew up, for the first meet- 

 ing, an address explanatory of the design and objects of the 

 Institution. This address is given in the Annals for March, 1821. 

 He afterwards communicated three papers to the Society, which 

 were printed in the first volume of its Transactions. 



The history now advances towards the close of a life which 

 had been long struggling with labours disproportion ed to his 

 strength, and was atlast seen to sink under the workings of a 

 mind too powerful and too active for the mortal part with which 

 it was united. The progress of his disorder was slow, but the 

 steps of it were strongly marked. At no time since his return 

 from his last journey, could his health be considered as well 

 established ; and besides many other occasional derangements 

 of his system, there was scarcely a single year in which the 

 exertions and confinement attending his Lectures did not bring 

 on some serious illness, frequently accompanying, but generally 

 following them ; and when these were over, instead of relaxation

 series of the Annuls contain papers on various other subjects by Dr. C. ; and the last he 

 ever wrote will be found in the number for March, 1822 ; N. S. vol. iii. p. 195.
