93C, 94C, 95C, and 96C, Plate IX., represent a specimen in my collection. Of these, some of the keys entered at the end of the tube; others are put in at the side, as shown in fig. 97C, Plate IX. The key, which, like the lock, is of brass, is placed in a handle, which shuts up like the handle of a knife (as shown in fig. 96C, Plate IX.) for convenience of transport. Another specimen from Japan (represented in figs. 98C and 99C, Plate IX.) resembles exactly the Toomkoor specimen from India, the springs being compressed by means of a revolving key. This must certainly be regarded as the first stage of improvement upon the original Roman lock, and its employment in Europe, India, and Japan is noteworthy. Amongst the specimens of these tubular spring locks, which appear to show evidence of connection over wide areas, are those which are constructed in the forms of animals. Figs. 100C and 101C, Plate IX., is a representation of a bronze padlock in the form of a fish, now in the Louvre, at Paris, figured by M. LIGER. It is there described, though not without hesitation, as an Egyptian lock; if so, it is probably of the Romano-Egyptian period: the springs enter at the mouth of the fish, and are released by a key put in at the tail. Figs. 102C, 103C, 104C, Plate IX., represents a precisely similar fish-shaped padlock of iron from India, and now in the India Museum. Figs. 105C and 106C, Plate IX., is a Roman bronze lock in the form of a lion or horse, in the possession of Dr. JOHN EVANS, F.R.S., and here copied by his permission; a similar one is in the British Museum. Figs. 107C, 108C, and 109C, Plate IX., is another, also in the form of a lion, and about the same size, from China, in the collection of Mr. CHUBB, the well-known locksmith. In all these the springs enter at the stern of the animal, and the other end of the bolt turns up and back in the form of a tail, and enters the neck of the animal behind the head. The key in the Chinese specimen has a peculiar secret contrivance to prevent its being inserted in the hole for it by anyone not acquainted with its construction. The head of the key will not enter the keyhole unless the handle end is put in first and slipped along the shank of the key, as represented in the drawing, fig. 109C, Plate IX. Mr. ROMILLY ALLEN, whose work on Scotch wooden tumbler locks I have already quoted, refers incidentally in his paper to spring locks, and says that he has himself seen them used in Persia in the forms of animals. We are thus led to infer that the practice of making them in these forms may have existed, or may still exist, continuously throughout the region referred to, and that, like the mechanism itself, and like many other articles of commerce, they may have passed by traffic from place to place, and been copied and adopted in the localities in which they are found. Fig. 110C, Plate IX., is a padlock obtained by me at Cairo; similar ones are in common use on out-houses
