Among the local Museums of recent foundation, it would be difficult to find one of more scientific interest and importance than that of the Malton Field Naturalists' and Scientific Society. The commencement of the collection, indeed, was made so lately, that it might naturally be expected to have attained little beyond the nucleus-stage; but as an exponent of local Natural History it already rivals many of the older Museums, and the object of the present notice is briefly to call the attention of palæontologists to the material it affords for all interested in the investigation of Jurassic and Cretaceous fossils.
