 M. P. c. MEDICAL AND SANITARY NOTES
 Eyesight of Soldiers.-The Lancet states that a surgeon in the United States navy reports as the result of an examination in Japan the finding in that country, among 1,200 soldiers, some ]. .5S per cent who were red blind 1 and O.S33 per cent who were green | blind; among 373 boys, per cent who 1 were red blind, and among 270 girls, | 0.4 per cent. Of 596 men in Kioto, | 5.45 per cent showed defective color l sense. Dr. Fielde, of Swatow, China, examined 1,200 Chinese of both sexes, | using Thompsons we'll known wool tests; among COG men were nineteen who were color blind, but among 500 women only one. It seems, therefore, that the percentage of color blindness among Chinamen is about per cent, and consequently does not vary great ly from that in Europeans. It was found, however, by Dr. Fielde that fully half the number who were test ed mixed I'D blue and green, and, ac- cording to this Investigation, many of that race are quite blind to the per ception of violet colors.
 Household Sources of Disease.-TO avoid some of the liabilities in this direction, the official inspector, of plumbing in Providence, R. l., calls the attention of householders to cer- tain points, among which are the fol- lowing: That the fixtures on the diff | feremt floors be placed over each other, so as to avoid horizontal soil and waste pipes, and that all the pipes be air tight, as shown by prop | CT test; that the continuation of the l house drain outside of the house to the sewer or cesspool be properly laid; that each water closet have suffic- tent supply of water, discharged with sufficient force when emptied com pletely to SCOUT the traps and branch
 waste pipes; that all objects be ex- 1 cluded from the water clasat> --w';iiidsn are likely to obstrylct the pipes, the
 traps to be so. arranged also as to
 resist siphlone ge. The point is also
 made that wien a fixture IS not to be
 in use for some time arrangements
 are necessary for preventing the wa
 ter seals in the traps from being
 broken, by substituting oil for wa
 ter.
 Safety Surgical Instruments. The arrest of bleeding in surgical opera tions is now said to be assured by l means of an instrument due to the in. genuity of Lawson Tait. A platinum | wire, so arranged as to carry cur rent of electricity, is inclosed in the blades of pair of steel forceps o1 l any other required instrument, tht } wire for this purpose being insulated 7 by bed of burnt pipe clay. This ar rangement being perfected, a currenr of suitable voltage is turned on, the
 artery seized and compressed, and il [ few seconds the tissues and ameria walls are so agglutinated that tht l passage of blood is rendered impossi

 about lS0 degrees F., the fact being
 thus apparent that the principle in {: volVed in this device is different from
 that of electrical cauterizing instru
 ments.
 Chemical Adulteration of Milk ? According to a statement in the Re
 Vue Scientifique, the chemical adul :; iteration of milk is one of the hygi
 chic factors now to be dealt with. T. ) seems that M. Deniges of Bordeaux
 having obtained possession of three samples of yellow powder used by
 certain milkmen of Bordeaux to pre-
 serve their milk, made a chemica
 analysis of it. This analysis showet 9 that two of the powders were com posed wholly of neutral chromate O 3 potash, that the third was a miNtur, Of one part bichromate of potash an(
 1%aI oI,
 the suspected milk had been adulter 9 ated with the last substance in tn, 7 proportion of 0.30 gramme to the litre t say hve grains to the quart The al ? kallne chromates are, in fact. DOW s erful antiseptics, capable. even il 3 small quantities, of retarding lacti l fermentation very noticeably, if no t Of stopping it entirely. But becaus l of the deleterious action of these salt. s on the organism, the Revue calls em e phatically for their complete exclu l sion from food substances, and par tlcularly from milk, of which so man, e young children drink relatively larg
 quantities.
 e Air of High Attitudes . upon the fact of the marked enlarge : ment of chest capacity which is oftel V found after few months residence 1n the high Alps, and the tendency t, I development of compensatory em ? physema around the diseased and con
 tracing portions of the lungs, a writ
 CT in the Hospital refers to the evi = dence, as recently shown, that no ,. only do the chest muscles adapt them r selves to the new conditions present - ed by that region, but that the bloc,
 itself becomes altered in response t, a the lessened amount of the more rare ], fled oxygen which each blood corpus
 cle can cslrry. The effect noticed 0 ,, this process of adaptation is that th
