36 ON NATURAL HISTORY MUSEUMS. from room to room ; but the practice does not appear to have been always satisfactory. At any rate a visitor in the beginning of the last century, was led to complain that the conductor treated the company to "witticisms on various subjects of natural history, in a style of vulgarity and impudence, which I should not have expected to have met in this place."52 Formal demonstrations in a museum are generally attended with more difficulty than most people imagine ; and after much experience, both as a listener and as a demonstrator, I was led some years ago to suggest that the formal demonstration, or lecture, should be given in a neighbouring room rather than in the midst of the cases.53 It is gratifying to find that at the Essex Museum arrangements are now being made, whereby a convenient room, with electric lantern and screen, will be placed at the disposal of those who desire to give demonstrations in illustration of the contents of the museum. In a paper on the utilization of local museums read at the last meeting of the British Association, the Rev. W. Johnson, of York, described the excellent work of Mr. Crowther, the Curator in Leeds, in lecturing to the schools, which systematically visit the museum ; and considering the great value of such work he strongly advocated its extension, with payment by the local authorities for the additional labour thus thrown upon the Curator. "This work," said Mr. Johnson, "is at any rate as well worthy of this support as are free libraries, or municipal bands, or art-galleries."51 Apart from formal lectures and demonstrations, a visitor to a Museum would often be glad of a description of some particular object, or group of specimens, of exceptional interest, and would be quite willing to pay a small fee for such a description by some competent person. Prof. Anton Fritsch, of Prague, has playfully suggested that the day may come when a visitor, standing in front of some interesting specimen, will have simply to drop a coin into a slot connected with a phono- graph, and forthwith he will hear a short discourse on the specimen in the very words, nay, even the very voice, of some 52 Journal of a Tour and Residence in Great Britain, in the years 1810-1811.
