The Naturalist. 



Liversedge, Birkby, Mirfield, and 

 Middlestown. The report of the 

 last meeting, held at Luddenden 

 Foot, on July 10th, as printed in 

 the "Naturalist," was unanimously 

 adopted, after which the president 

 briefly addressed the meeting, limi- 

 ting his remarks to congratulating 

 the members on the establishment 

 of a new Natural History Journal 

 in connection with the Society, and 

 strongly urging the desirability of 

 each member becoming a subscriber, 

 and as far as possible a contributor 

 to its pages. He concluded his 

 remarks by reverting to the loss the 

 Society had sustained in the death 

 of one of its oldest members, Mr. 

 John Hodgson, of Wakefield. — Mr. 

 J. Wilcock, of Wakefield, at the 

 request of tne president, then intro- 

 duced the subject of the conchology 

 of the district. Within a radius of 

 eight miles he stated he had col- 

 lected during the last few years 

 upwards of 195 species and varieties 

 of land and fresh water shells. He 

 considered the district very prolific, 

 and though there had been a large 

 number of species collected during 

 the ramble, had the weather proved 

 favourable, there might have been 

 many more. He then named the 

 specimens produced, amongst which 

 were the following : — Helix aspersa, 

 and its vars. conoides and tenua, 

 H. nemovalis, vars. hyhrida, major 

 and hortensis, H. virgata, H. 

 caperata, vars. major and ornata, 

 H. cantiana, H. hispida, H.pygmoea, 

 H. pulchella, H. aculeata, Zonites 

 stellaris, Z. nitidida, Z. fulvus, 

 Clausilia rugosa var. twmidula, 

 Pupa minuUssima, &c. The Rev. 

 W. Fowler, M.A., of Liversedge, 



was next called upon to report on 

 the Magnesian Limestone formation, 

 which he illustrated by organic 

 specimens and chemical analysis, 

 showing the difierent proportions 

 of carbonate of lime and phosphate 

 of magnesia in the Knottingley and 

 Warmsworth limestone, the former 

 containing the larger proportion of 

 carbonate of lime, and the latter 

 that of phosphate of magnesia. 

 The plants, numbering upwards of 

 100, were then named by the Rev. 

 W. Fowler, Mr. John Armitage, 

 and Mr. R. Jessop. The series 

 was of an interesting description, a 

 large number belonging more par- 

 ticularly to limestone districts, 

 amongst them being : Gentawea 

 nigra, Erigeron acre, Reseda lutea, 

 B. luteola, Silene inflata, Carduus 

 nutans, Conium macidatum, SoncJius 

 asper, Filago germanica, Epilohium 

 parmflorum, Origanum vulgare, 

 Agrimonia Eupatoria, Torilis 

 anthriscus, Echium vulgare, Senecio 

 erucoefolius. Polygonum Hydropiper, 

 Matricaria Chamomilla, Lycopus 

 europceus, Malva sylvestris, Alope- 

 curus genicidatus, Aira flavescens, 

 Holcus lanatus, Sedum acre, Ballota 

 nigra, Calaminfha Clinopodium, 

 Erysimum cheiranthoides, Inula 

 dysenterica, Silaus pratensis, Thal- 

 ictrummajus, Poa rigida, Pimpinella 

 Saxifraga, P. magna, Verhascum 

 Thapsus, &c. — The geology of the 

 district was treated upon by the 

 Rev. W. Fowler, who described 

 the various sti'ata above the coal 

 measures, comprising the lower red 

 sandstone, the magnesian lime- 

 stone, the lower red marl and 

 gypsum, the upper slaty limestone, 

 and the upper red limestone, &c.
