they might see that the Entoinostraca of to-day were the survivors of a 

 very ancient race, as shown by their fossil remains in the rocks, where 

 bivalvecl forms were abundantly represented, some being of gigantic 

 size. Such visits to the Museum would be found both interesting and 

 instructive, and the place itself a very diiferent one from what it was 

 to people who, wandering aimlessly through the building, seemed only 

 to be trying how many miles they could cover in the course of an after- 

 noon. The late Prince Consort always insisted upon a systematic way 

 of visiting the Museum, and would not allow the Royal family to roam 

 about the galleries, but invariably arranged beforehand what they were 

 to be shown, and they were at once taken to that particular part of the 

 collection, and after having seen it, and had it explained to them, the 

 visit ended. Museum headaches and boredom are thus avoided.
