YORKSHIRE NATURALISTS AT HARROGATE. 243 



four degrees. ' From this it appears that the anticlinal of Harrogate 

 dies out to the east, and that there is no great anticlinal ridge of 

 Carboniferous rocks below the Permian and Trias.' 



Time rapidly fled, and the party had no leisure to examine the 

 Boggs Field with its varied medicinal springs, so often described, 

 and of such vast importance and value ; therefore they briefly 

 examined the section of the Harrogate roadstone in the Cold Bath 

 Road. The dip is here in a south-easterly direction, about 20 , 

 but the anticlinal causes it to dip on the opposite side of the little 

 valley, at a steep angle nearly 6o° due north. This illustrates the 

 magnitude of the disturbance. This roadstone is extremely well 

 known, and Prof. Phillips considered it to be the equivalent of the 

 main or twelve-fathom limestone of the Yoredales, but, as the 

 Government geologists truly say, ' as it occurs at a considerable 

 distance from the nearest undoubted Yoredale Rocks, and is only an 

 mlier here at Harrogate along the line of the anticlinal, it is difficult 

 rather to fix its exact horizon.' However, that it is one of the 

 Yoredale Limestones there is no doubt, from its formation and its 

 fossil remains. This limestone has been described as an exceedingly 

 hard silicious rock or a calciferous grit, containing encrinites in great 

 numbers. All geologists know it from its constant presence on the 

 stone heaps by the road side. 



The remnant of the party were now thoroughly tired, and, more- 

 over, had missed the ' five o'clock tea,' arriving only just in time to 

 enable Mr. Adamson to put in a brief report at the general meeting 

 about seven o'clock. Still it was acknowledged that a valuable and 

 a charming excursion had been made, the instruction gained quite 

 neutralising the late arrival, and arousing a desire to see more of this 

 grand geological field. 



For the section of Micro-Zoology and Micro- Botany, its secretary, 

 Mr. J. M. Kirk, of Doncaster, reported that the water in most of the 

 ponds examined was too stagnant for the higher forms of life, and 

 Crimple stream too rapid to yield anything notable in the micro- 

 scopic line. The following is his list : — 



Infusoria. Rotatoria. 



Chilodon cucullulus. Hydatina senta. 



Dileptus folium. Diglena lacustris. 



Loxodes bursaria. Pterodina patina. 

 Euplotes monostylus. 



Vorticella nebulifera. 

 Stentor miilleri (abundant). 



Arachnida. 



Uvella virescens. Atax histrionicus (Hydrachna 

 Paramecium aurelia. histrionica). 



Uroleptus piscis. Tardigrada.
