288 Obituary — Joseph Nolan. 



on and around the coral or bryozoan masses was deposited a coccolitli- 

 ooze of the same constitution as that lying under them. The 

 formation of corallian or bryozoan limestone was not connected with 

 any particular period, so that these rocks va^y occur at any horizon 

 in the coccolith-limestone, the corals in island-like reefs but tlie 

 bryozoa in extended sheets. 



The Uppermost Chalk of the Baltic contains neither Belemnitella 

 mucrouata, as stated by Prestwich (Geology, 1888, ii, pp. 7 and 302),. 

 nor any other belemnite. It was formed in the period between the 

 Upper Maestrichtian and the Eocene, and has no marine equivalents-

JOSEPH NOLAN. 



BoKN 1841. Died April 20, 1902. 



The late Mr. Joseph Nolan, who died at Clonturf, Dublin, on the 

 20th April, was born in Queen's Countj'^, Ireland, in 1841. In early 

 life he attained a sound knowledge of geology from attendance at 

 Jukes's lectures in the Museum of Irish Industry (now Koyal 

 College of Science), Dublin, 



In 1867 he was nominated by Professor Jukes (then Director of 

 the Irish Geological Survey) for appointment as one of the Assistant 

 Geologists, and in this capacity surveyed with great keenness many 

 important districts in Ireland. Prominent amongst these were 

 the complicated areas of South Mayo and the volcanic region of 

 Carlingford and Slieve Gullion, ot which latter the late Sir Andrew 

 Eamsay wrote (in his preface to Mr. Nolan's memoir on Sheet 70' 

 of the one-inch geological map of Ireland) : " There is as much 

 interesting matter for discovery and description crowded into a small 

 area as there is to be found in any part of the British Isles." The- 

 geological features of the wild mountainous tract which extends 

 through North Tyrone into the Dungiven region in Co. Derry, of 

 the country surrounding Derry City, and portions of Donegal, were 

 ably dealt with by Mr. Nolan ; his work in the field being 

 explained in numerous descriptive memoirs which he wrote to- 

 accompany the maps. 



Mr. Nolan, who was for some thirty years a member of the 

 Eoyal Irish Academy, took deep interest in the literature, lore, and 

 antiquities of his native country, and his work on the " History and 

 Antiquities of Glendalough " is well-known in antiquarian circles. 



Upon the reorganization of the Irish Geological Survey in 1890, 

 Mr. Nolan was appointed " Senior Geologist " to take charge of the 

 office, a post from which he retired only within the past year. 

 His kind and gentle presence will long be greatly missed by his- 

 colleagues on the Survey, and by all others who enjoyed the 

 pleasure of his friendship. E. C.
