382 Mr. H. Denny^s Sketch of the Natural History cules^ which are coloured, laterally free, articulated to each other end to end, and containing very minute globules of fe-cula which turns blue on the application of iodine. The pol-len-tubes which penetrate between the utricules of this tis-sue are readily detected by their much greater tenuity, the absence of articulations, and the very minute granules inclosed in them. These observations satisfactorily dissipate all doubts as to the functions truly stigmatic performed by the parts which in the Campanulas correspond in position and appearance to the stigmas of other plants, and prove that these collecting hairs i^^ polls collecteurs'') exercise only a secondary office in fecun-dation.

I have only in-serted what have come under my own immediate knowledge and inspection, or have been communicated by scientific friends residing in the neighbourhood. There are many sources from which information might have been obtained to swell this list, I am fully aware, but to these I have not had access; such a ske-leton as it is,however,I am not without hopes maybe of service, as a foundation for the cultivators of natural history whose eye it may chance to meet, and whose means of acquiring import-ant additions or corrections will enable them to finish the sketch which I have only attempted in outline. Of the mam-malia frequenting this neighbourhood but little can be said; indeed little can be expected in the vicinity of large manufac-turing towns, surrounded on all sides by smaller seats of in-dustry, for such many of our villages are become, together with the clearing of moorland and inclosing of commons, nu-merous new roads, &c., the necessary concomitants of the spread of population and commerce, all of which are inimical to the wild inhabitants of a country.
