FRIDAY EVENING, APRIL 9, 1858. 

 Charles P. Croker, M.D., M.R.I.A., Vice-President, in the Chair. 



The Minutes of the previous Meeting having been read and con- 

 firmed — 



Mr. R. P. Williams exhibited a black-and-white variety of the field 

 mouse {Mus sylvaticus), which had been presented to the Society by C. 

 J. "Walmeslie, Esq., whose attention was first called to the specimen in 

 question by the fact of its being possessed of the power of producing a 

 chirping noise. Instances of these so-called '' singing mice" had already 

 been noticed on several occasions, the so-called song being, probably, 

 dependent on disease in the animal. Varieties of this species as to colour 

 were rare in the wild state.

 in selecting from the many notes which I have made regarding the deep- 

 water animals of the west coast, especially the fishes. 



The existence on the west coast of Ireland of botanical and zoolo- 

 gical types similar to those of the shores of Cornwall and Devon, and of 

 Spain, Portugal, and the Mediterranean, has often afforded subject- 

 matter for the meetings of this Society. It has been supposed that 

 currents setting from the southward, and here mingling, have raised the 

 temperature of the water, and carried to these shores the denizens of 

 those around the Tagus and Mediterranean. It is known to nautical 

 men that a stream more or less perceptible, and termed Rennel's Current, 

 has had the effect of carrying ships out of their course to the northward, 

 when seeking to make the Cape from the "Western Ocean ; but it has
