2 Jackson, Deposit of the Lozver Bann Valley. 



and with the kind assistance of Messrs. R. Welch and 

 R. Bell, both of Belfast, he accumulated a considerable 

 amount of material, both in specimens and details of 

 various sections. His keen interest in the matter led him, 

 in 1903, in spite of his advanced years, to go over and 

 personally investigate the district under the guidance of 

 the above-named gentlemen. It was his intention, ulti- 

 mately, to record his observations and give a detailed 

 account of the various finds. Failing health and other 

 causes prevented him from carrying out his project, and 

 in 1907 he requested me to carry on his observations, 

 placing all his MS. notes, and fine collection of imple- 

 ments, since presented by him to the Manchester Museum, 

 entirely at my disposal. 



At his request I spent some time in this district early 

 in 1908, and made many further useful observations. 



His death has, unfortunately, somewhat interfered 

 with my original plans, and I have, therefore, thought it 

 advisable to place on record the observations made, so far 

 as they have gone, and to describe the more interesting 

 objects in his collection, along with others contained in 

 the magnificent series belonging to Mr. R. Bell, and 

 coming from the same locality. 



Various accounts of implements found in this neigh- 

 bourhood have been written by several authors, including, 

 amongst others, the late Sir John Evans ; the Rev. James 

 O'Laverty ; Mr. Robert Day, junr., of Cork, and Mr. W. J. 

 Knowles, of Ballymena, a bibliography of whose papers 

 will be found at the end. 



The peculiar character of many of the objects 

 described in this paper has not been touched upon 

 by previous writers, they having only been revealed 

 during the recent extensive working of the diatomaceous 

 deposit.
