securing of greater uniformity in the modes of tabulating and 

 publishing results. In order to understand how far the mem- 

 bers of our society may be able to co-operate with the British 

 Association, it may be well to glance at the constitution of the 

 latter. The work of the Association is divided into eight 

 sections, each identified by a letter from A to H. The sections 

 are as follows : — A, Mathematical and Physical Science ; B, 

 Chemical Science ; C, Geology ; D, Biology ; E, Geography ; 

 F, Economic Science and Statistics ; G, Mechanical Science ; 

 H, Anthropology. Each section has its own committee of 

 management, and, in addition, there are special committees 

 appointed to investigate special subjects ; it is with these special 

 committees that the corresponding societies can most usefully 

 co-operate. Mr. Gray then dealt with the work of a number 

 of the special committees, pointing out the way in which our 

 Naturalists' Field Club may usefully co-operate with them. Under 

 section C — Geology — he referred to the Underground Waters 

 Committee,appointed to investigate the circulation of underground 

 waters, and their quality and quantity, questions of the deepest 

 importance in towns and districts where wells are habitually 

 used, and particularly in Belfast, where costly wells are often 

 sunk for trade purposes. The work of the Erratic Boulders 

 Committee, the Seacoast Erosion Committee, and the Geological 

 Photographs Committee was dealt with as affording fields in 

 which the Club may render valuable aid to the Association. 

 Mr. Gray stated that the photographs of geological subjects, 

 sent from Belfast to the Leeds meeting, were highly appreciated. 

 In the section of Biology the work of the Committee on Fresh- 

 water Fauna and Flora, and of the Committee on the Disappear- 

 ance of Native Plants, may well fall within the scope of our 

 Society ; and in the Anthropological Section a wide field is open 

 to us in the way of assisting the work of the Prehistoric 

 Remains Committee by systematically cataloguing and mapping 

 the ancient monuments in which our district is so rich. Mr. 

 Gray here exhibited the 1 -inch scale Ordnance Maps of Counties 

 Antrim and Down, on which all the ancient monuments which
