From models specially made for this work we find that if leather was used at all it must be after the manner of No. 9 on Plate I. Here the rings are covered with the leather on both sides, so that there is no possibility of their gaping, and, in addition, the leather being pressed against the rings, on the outside by wear and usage and on the inside from the pressure of the body, would show ring-markings on front and back which might be represented in the manner shown in the illustration. The drawback to this theory is not only the weight of such a defence, but also the heat from lack of ventilation. By far the most practical theory put forward is that of Mr. Waller,[4] who gives an illustration of a piece of Oriental mail with leather thongs threaded through each alternate row of rings. This gives a certain solidity to the net-like fabric and yet does not add appreciably to its weight. No. 11 on Plate I shows this arrangement drawn from a model, and when we compare it with the figures below, taking into consideration the difficulty of representing such a fabric, we are forced to admit that this last theory is the most practical. This is especially so in No. 12; for the mail covering for the head is probably made in one piece with that of the arms and legs, but the leather thongs have been omitted on the head and hands to give greater ease of movement. Before leaving the subject of fabrics it may be well to warn those who consult Meyrick that this author is rather prone to enunciate theories of the different forms of mail which, like that of the banded mail, do not work well in practice. He mentions, among many other varieties, what he calls 'Mascled' mail. He asserts that this was formed of lozenge-shaped plates cut out in the centre and applied to linen or leather. He says that it was so called from its likeness to the meshes of a net (Lat. _macula_). Now when we consider that the word 'mail' itself comes to us from the Latin 'macula', through the French 'maille' and the Italian 'maglia', we find that Meyrick's 'Mascled mail' is but a tautological expression which can best be applied to the net-like fabric of the interlinked chain defence, and so his 'Mascled mail' would more correctly be styled a 'Mascled coat', and this coat would probably be formed of the chain variety as resembling the meshes of a net more closely than any other fabric. Double mail is sometimes to be met with on carved monuments, and this would be constructed in the same manner as the single mail; but two links would be used together in every case where one is used in the single mail.
