Pre-Columbian Musical Instruments in America.—In a recent article in the Popular Science Monthly (November, 1898), entitled Was Middle America Peopled from Asia? I insisted that if there had been any invasion, peaceful or otherwise, sufficient to have affected even in the slightest degree the arts, customs, and religious beliefs of middle America, then, associated with these influences, we should find traces of Asiatic utensils, implements, structures, such as sandals, weapons, pottery, wheels, plows, roofing tiles, etc.; in other words, just those objects most intimately associated with man. I especially considered the absence of stringed musical instruments and coincided with Dr. Otis T. Mason in the belief that there was no evidence of a pre-Columbian stringed musical device. This question has been variously discussed and the following references bear on the subject: A short note in the American Antiquarian for January, 1897, by Dr. D. G. Brinton, entitled Native American Stringed Musical Instruments. The author frankly admits, however, that the cases cited may all have been borrowed from the whites or negroes. Mr. M. H. Saville in the American Anthropologist for August, 1897, described A Primitive Maya Musical Instrument, though he makes no pronounced statement of its pre-Columbian origin. Dr. Mason, in the American Anthropologist for November, 1897, discusses the question under the title Geographical Distribution of the Musical Bow, and in this paper says, "I have come to the conclusion that stringed musical instruments were not known to any of the aborigines of the western hemisphere before Columbus." In my paper I insisted that "had this simple musical device been known anciently in this country, it would have spread so widely that its pre-Columbian use would have been beyond any contention." Mr. Saville finally, in the American Anthropologist for September, 1898, shows apparently the existence of a pre-Columbian stringed musical device in a paper entitled The Musical Bow in Ancient Mexico, and presents his proof in the form of a reproduction from an ancient Mexican codex of an orchestra of six performers. One of the figures, according to Mr. Saville's interpretation, is holding a musical bow in his left hand while with his right hand he is striking the cord with a forked stick. Claiming no skill in the interpretation of these quaint and concentrated Jack-of-heart figures, I readily yielded to the authority of Saville in this matter, and so acknowledged in a footnote in my paper which I was enabled to insert after the pages were made up. Within a few days I have received a letter from Mrs. Zelia Nuttall, the eminent American paleographist, to whom we are indebted for the most profound researches in connection with these ancient codices. In this letter Mrs. Nuttall refers to Sahagun's great manuscript, wherein she says: "The native musical instruments are repeatedly enumerated. The turtle's shell figures among them, but there is no trace of a stringed musical instrument ever having been known or employed in ancient Mexico." (The Italics are hers.) Mrs. Nuttall then says that the object held under the arm of the musician which has been recognized as a musical bow is undoubtedly a turtle's shell. In support of this view she sends me a tracing of the figure from the original manuscript which is now in Vienna, in which the entire object under the arm of the player as well as the forked stick is colored blue (Fig. 1). A photograph is also inclosed from another ancient Mexican manuscript in course of publication by Mrs. Nuttall. In this (Fig. 2) the player has the turtle's shell and is pounding on it with a pronged stick, horn, or branch, while in the other hand he holds a rattle and at the same time sings, the notes being graphically portrayed as they come from his mouth. It will be observed that it is the plastron or ventral surface that he is striking, as shown by the notches in its forward and hinder edges, though the plates are incorrectly drawn. In the figure given by Mr. Saville the player is holding the turtle's shell in precisely that position that would enable him to strike the plastron. Even in Mr. Saville's figure the marginal plates of the shell are plainly indicated. By holding the figure face downward the shell is thrown in a normal position with the back uppermost, and what was mistaken for the string of the instrument is the outline of the back of the turtle correctly delineated. With the above figures I give the outline of the left arm and body of a friend who posed for me while holding a large South American turtle under his arm. I have drawn the plates of the carapace to more clearly indicate the position of the turtle's shell. In the original codex, as before remarked, this portion is colored blue. In this attitude the flat plastron forms the drumhead, so to speak, the carapace acting as a resonator. I am sure that Mr. Saville will agree with me that Mrs. Nuttall's attribution is the correct one.

Rebreathed Air as a Poison.—The following extracts are taken from an article by Dr. John Hartley, in the Lancet: "The fresh-air treatment of consumption" appears to be made up of three essential factors: (1) the discontinuance of the supply of bacilli from without; (2) the supply of an abundance of nutritive material to the tissues; and (3) the supply of an abundance of fresh air uncontaminated by the products of respiration. This seems to mean that the tissues, if not too enfeebled, may be trusted to deal with the bacilli already present if their metabolism is kept going at high pressure. Fresh air is now the "official" remedy in the treatment of tubercle. Why is it so ignored in the case of other diseases? Has the pneumonic or bronchitic no need of special ventilation because his microbe is of a different breed? The air was intended not only for phthisical patients or patients suffering from pneumonia but for all—diseased and healthy alike—and it is still the natural medium in which the poisonous products of tissue metabolism excreted by the lungs are further broken down and rendered harmless. Dr. A. Ransome has done great service not only by his onslaught on "air sewage" but also by his coinage of the term; for a thoroughly good opprobrious epithet resembles a good wall-poster in its power of arresting and enchaining the attention of the many. It was long ago pointed out that certain constituents of expired air are intensely powerful nerve poisons. These considerations should surely make us look on rebreathed air and sewer gas, not as mere carriers of accidental poisons, such as influenza and pneumonia and the like, but as poisons per se, and I wish to be allowed to record a few very imperfect observations made by myself during some years past chiefly on the subject of rebreathed air, with certain inferences which I think tend, however feebly and imperfectly, to show that the poisons we expire have per se very definite effects on tissue metabolism and need not a mere perfunctory admixture with fresh air but very large and very continuous dilution before they are rendered innocuous—that is to say, innocuous to all; for while some persons appear to be almost immune, others seem intensely susceptible. The first observation I will allude to was made in the autumn of 1896, in cool weather. I had to take a long night journey by rail after a long and hard day's work. The train was full and the compartment I entered was close; so, as I was tired and fagged, I sat in the corridor by an open window, well rugged up, throughout the journey. The compartment was completely shut off from the corridor by a glass door and windows, through which I could freely inspect its occupants. Two remarkably fresh-complexioned, wholesome-looking young fellows got into the compartment at York. They formed a remarkable contrast to the pallid and fagged-looking travelers already there. The windows and ventilators were carefully closed, and the newcomers, with the rest, settled off to sleep and slept soundly for nearly four hours, with the exception of a few minutes' interval at Grantham. When aroused on nearing London they, like the other occupants of the compartment, were haggard and leaden-hued, their fresh color was entirely gone, and they looked and moved as if exhausted. I examined my own face in the lavatory mirror at the beginning and end of the journey and could see but little alteration in my color; if anything, it was rather improved by the end of the journey. The second case occurred early in 1897. I was asked to see a woman, aged about forty-eight years, who had been treated in a neighboring town for many weeks for bronchitis and asthma following influenza. She had relapsed about a week when I first saw her. She was then sitting up in bed; her face was leaden-colored, her skin was clammy and sweating, with a feeble, quick pulse, and the heart sounds were indistinguishable owing to wheezing; there was some crepitation at the bases. The temperature was about 101° F. The weather was cold, but after wrapping her up, with a hot bottle to her feet, the window was well opened. Her color improved in a few minutes and the sweating ceased soon after. But it and the blueness returned if the window was shut for any time. It was directed to be kept open night and day, and I could see from my house that this order was carried out. Although on one night the thermometer showed 14° F. of frost the chest was clear of noises and she was convalescent in eight days. If fresh air needs warming she ought to have died. Why do most men feel so tired after an afternoon's work in a crowded out-patient room? Why is a long journey in a full railway carriage, even with a comfortable seat, so exhausting to many people? Personally an hour or two in a full carriage with the windows shut will give me numbness in my feet and legs and knock me up for the day, while a railway journey in an empty carriage with open windows does not affect me at all. But most people will be willing to admit that any kind of crowd is tiring. It is to me difficult to resist the impression than an overdose of waste products, whether of one's own or other people's, must generally interfere with the metabolism of nerve tissue. Women as they grow older are apt to live much indoors. I believe the fat, flabby, paunchy woman, whether purple or pale, with feeble, irritable heart and "inadequate" kidneys, is usually the victim of rebreathed air. A "close" room will infallibly give me an abdominal distention and borborygmi within half an hour, and I am inclined to think the purity of the air breathed by the dyspeptic quite as important as his regimen or his teeth. It must, I think, sooner or later be recognized that many of the increasing ills which it has been the fashion to charge on the "hurry and brain fag" incidental to a high state of civilisation and a large population are in reality due to the greater contamination of the air we breathe by the waste products of that population, and that toxines excreted by the lungs will in time take high rank among these as both potent and insidious. If this should come to pass, the present ideas anent ventilation must be abandoned as utterly futile, and the need will be felt, not of letting a little air in, but of letting waste products out.
The Utilization of Wave Power.—The utilization of the energy which goes to waste in the movement of water, in waves, tides, and waterfalls, has been a much-studied problem during recent years. The only one of these three phenomena which has as yet been at all extensively commercially harnessed is the waterfall. There have, however, been a number of wave and tide motors constructed. The most recent and perhaps the most promising of these is the type invented by Mr. Morley Fletcher, of Westminster, England. He has made a special study of the problem of motion of the sea, and has already successfully constructed a hydraulic pump, an electric motor, and a self contained siren buoy in which the energy is obtained entirely from wave motion. The great possibilities in this direction for cheap and efficient power plants have not been appreciated by seacoast towns, but it is stated in Industries and Iron, from which we have taken the above particulars, that Mr. Fletcher is at present devoting his attention to devising schemes and designing apparatus for pumping sea water for shore purposes, ore washing, driving electric machinery for town lighting and power plants, buoys for marking harbors with beacons and fog horns, and the many other purposes to which such a constant and inexhaustible source of energy is applicable.
