382 Mr. H. Denny's Sketch of the Natural History 



cules, which arc 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 arc 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 

 ("polls collecteurs") exercise only a secondary office in fecun- 

 dation. 



XLVII. — Sketch of the Natural History of Leeds and its 

 Vicinity for Twenty Miles. By Henry Denny, Esq. 



In submitting this outline of the vertebrate inhabitants of the 

 district of twenty miles round Leeds, I do not wish it to be con- 

 sidered as anything like perfect or complete. 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. 



Beginning with the order Ferae, I very much doubt whether
