Mr. Yarrell read a letter addressed to him by Dr. Lukis, of Guernsey, containing 

 some observations on the natural history of the Channel Islands, and stating, among 

 other things^ that each island had to a certain extent a fauna of its own, as certain 

 reptiles, quadrupeds and insects found in one were not found in another, although 

 the distance between them was not more than eight miles in one case, and twenty 

 miles in another. Mr. Yarrell mentioned as a fact within his own knowledge, that 

 although the water in the canal at Stockbridge, Hants, was always one degree colder 

 than in the adjoining river Test, yet the May-flies invariably appeared from the canal 

 some days sooner than from the river.
