14 ON NATURAL HISTORY MUSEUMS. principally casts, illustrating the famous case of the Ancestry of the Horse. To all these collections which bear on natural evolution great value is imparted by the long descriptive labels, which have been drawn up by Mr. W. Cole. Not only here but all over the museum there are large labels and tablets, admirably composed, which make the collections self-interpreting, and offer to the visitor, who cares to read them, an excellent epitome of informa- tion on many branches of natural history. It is probable that by the casual visitor as he hurries through the museum they are unread and unheeded. Even the student who lingers over them may have but a faint notion of the labour involved in their composition. To put a scientific statement concisely yet clearly and in popular language is a task, the difficulty of which is known only to those who have had to face it. The labels in our museum are neat and legible, being either printed or type- written, whilst they appeal by their simplicity of expression to that unscientific individual, our familiar friend, who passes now- adays as the "man in the street." An American has said that our labels ought to be clear enough to "attract the newsboy and the boot-black."1' I hardly think our critic would find much fault in this respect at Stratford. The prime object of the Essex Museum is, of course, to illustrate the natural history of the county. The greater part of the Invertebrata are represented by a large and valuable collection of shells, crustacea, insects and other objects which are, or will be, preserved in two mahogany cabinets that have recently been placed in the museum. These beautiful cabinets contain upwards of 100 glass-topped drawers, each having a stop at the back so that it may be partially drawn out by the visitor, and its contents inspected without fear of damage. In this way the specimens will be preserved from deterioration by exposure to light, and yet remain freely accessible to the public. Notwithstanding the efforts of the curator there are still many gaps in the local collection, and members of the Essex Field Club may be reminded that they have it in their power to render the museum very material aid by contributing from the spoils which they collect.
