This report completes my labours for the present on British Fossil 
Potyzoa. The reports are not all that I could have wished, and in the 
earliest—the Carboniferous Report—there are many defects in the style, 
composition, and descriptive text that I, at present, lament, but the 
whole were unavoidable at the time. In the compilation of the various 
reports I have received from specialists much kindly help and attentive 
consideration—for all of which I return them my sincere thanks. To 
Professor P. Martin Duncan, F.R.S., and also to Dr. H. C. Sorby, F.R.S., 
names associated with mine as the Committee for the compilation of 
these reports, my thanks are also due for the extremely kindly manner 
in which they have given advice, and help by way of suggestion, when- 
ever solicited for the same. The General Committee of the British 
Association must also be remembered by me on account of their kindly 
consideration of my humble efforts, and for their pecuniary help. 
Fourth Report of the Committee, consisting of Professor W. C. 
Wituiamson and Mr. W. H. Batty, appointed for the purpose 
of Investigating the Tertiary Flora of the North of Ireland.

[PLATE I.] 
Tue Secretary regrets the unavoidable delay which has occurred in sup- 
plying this report, which should have been presented at the last year’s 
meeting of the Association. He has lately had an opportunity of 
pursuing his researches on the Tertiary Flora of the North of Ireland, 
and has been enabled to obtain some additional information as to the rela- 
tion of these deposits with that of other portions of the British Islands. 
Most important amongst these fossil plants is a second example of a 
fossil fern, which he believes to be identical with Lastrea Stiriaca (Unger). 
* I shall be sorry if such is the case, but I may have overlooked some papers on 
Paleozoic and Mesozoic Polyzoa. If so, I hope authors will communicate with me,
