It is impossible to make too many notes of a monument, and quite easy to make too few. The nature of the great majority of such notes must be left to the discretion of the traveller; but concerning all antiquities, from buildings to beads, it may be said that, at any rate, material, colour, dimensions, condition of preservation, arrangement of parts and character of ornament must be jotted down in the ever ready note-book. In the case of buildings, notes giving all dimensions are especially important, since the camera can seldom be brought to bear on all parts and details, and there is often not opportunity to draw out a plan on the spot. Of inscriptions certain facts must be recorded, viz., form of the stone; condition of its surface; the material and colour; on what sides complete, and on what not; actual dimensions; height of lettering; general character of lettering; whether well or ill cut, plain or ornate. Epigraphists’ notebooks are procurable in Germany and Austria containing divisions for the notes on all these points, together with a ruled space for the actual inscription. In the case of coins, the material, the ancient value, the weight (if possible), the state of preservation, and the images and superscriptions should be noted; of sculpture, the material, the dimensions, the degree of finish, and a minute analysis of the subject, the dress of the figure or figures, their gestures, attributes, and so forth. B.—CLEANING AND CONSERVATION. The traveller will not have occasion to render more than ‘First Aid’ to objects of antiquity, _i.e._ to clean them so that their true character may appear, and to consolidate them with a view to safe transport. He should do the least that is absolutely necessary, leaving all elaborate treatment to experts at home. The hints here given are therefore elementary, and concerned mainly with portable objects. In this connection these are best classified by the materials of which they are made. (_a_) _Gold._—Gold requires no immediate treatment, unless it be laid over a core of other metal, _e.g._ copper or bronze, which has oxidised out through cracks. This oxide can usually be removed by picking or by sharp scaling blows with a small hammer and chisel. If it is obstinate, use dilute hydrochloric acid laid on with a brush. The proportion of pure acid should not be more than one part to ten of water.
