How I hang over that case of treasures every time that I visit the Museum; foolishly fascinated perhaps, yet irresistibly so, looking and pondering. The fragment of a bulb that is left—for a fragment it is, only about three fourths of a whole—is, by the enthusiast’s valuation, beyond price. In one of the pipes, there is a piece of another bulb left sticking on the top; and, if you look closely, you will see the scored lines inside the pipe, and outside and inside the bulb, that were made so as to ensure close fitting when the bulb was pressed in. And look again, closely, and you will see at the top of each pipe, there is a little rim edge, and then a shallow groove about half an inch broad; and this, no doubt, was bound round with fibre or ivory or metal to prevent the splitting at the top, where the bulb was pressed in and made to fit securely, being, perhaps, slightly moistened by the lips, just as we do now when putting instruments together; and the operation was frequent, since the reeds, as I have said, were taken out after playing, and placed safely away in a little box called a tongue box. The pipes are three eights of an inch in bore, and the finger holes are oval and large, in their smaller diameter quite as large as the bore. I measured the distance between every hole, and so obtained the correct length of the instruments as in their original straight condition. By the kindness of Mr. A. S. Murray, then the esteemed chief of the department, I was able to take every particular I wished, and to calliper the bore of each pipe. The length of the longest pipe is thirteen and a half inches, and the shorter pipe is twelve inches and a quarter, just one and a quarter inches difference, which corresponds to the distance between each hole, showing that in depth of sound the pitch of the pipes differs by one whole tone. The details of measurement are of the greatest interest in the scientific analysis of these ancient musical instruments, and afford much valuable insight into the system upon which they were constructed in conformity with the music for which they were designed, and very evidently they tell us that the music played by the people was of a simple character and very limited in compass.
