410 Wernerian Natural History Society, 



of Clackmananshire, from the bed of the river Forth to the 

 base of. the Ochils, illustrated by a voluminous and very 

 distinct plan or section of those strata, done from actual 

 survey, and from the register of the borings and workings 

 for coal in Mr. Ersktne of Mar's estate in that district; 

 communicated by Mr. Robert Bald, civil engineer, Alloa. 

 In this first part Mr. Bald treated only of the alluvial strata* 

 In continuing the subject, he is to illustrate it still further 

 by exhibiting specimens of the rocks themselves. 



Mr. Charles Stewart laid before the Society a list of insects 

 found by him in the neighbourhood of P^dinburgh, with in- 

 troductory remarks on the study of entomology. It would 

 appear that the neighbourhood of Edinburgh affords no very 

 peculiar insects, and but few rare ones. The list contained 

 about 400 species ; which, Mr. Stewart stated, must be 

 considered as the most common, as they were collected in 

 the course of two seasons only, and without very favourable 

 opportunities. It was produced (he added) merely as an 

 incitement to younger and more zealous entomologists, 



At this meeting there were laid on the Society's table the 

 first two volumes 4to, with a volume of figures, of Comte 

 de Bournon's System of Mineralogy ; presented by the 

 author. 



At a meeting of this Society on the 13th of May, the 

 second part of Mr. Bald's interesting mineralogical descrip- 

 tion of Clackmananshire was read, giving a particular ac- 

 count of two. very remarkable slips or shifts in the strata, 

 near 1000 feet in depth, and by means of which the main 

 coal field of the country is divided into three fields, on all 

 of which extensive collieries have been erected. 



The Rev. Mr. Fleming, of Bressay, laid before the So- 

 ciety an outline of the Flora of Linlithgowshire, specifying 

 only such plants as are omitted by Mr. tightfoot, or are 

 marked as uncommon by Dr. Smith. This, he stated, was 

 to be considered as the first of a series of communications 

 illustrative of the natural history of his native country. 



Mr. P. Walker stated a curious fact in the history of the 

 common eel. A number of eels, old and young, were found 

 in a subterranean pool at the bottom of an old qua.rrv, which
