DDT AND MALARIATHAT DDT, already acclaimed for success in aborting

the typhus epidemic in Naples, now is helping to controlmalaria and fly-borne diseases, is reported by MajorGeorge C. Brother, of the Medical Corps, attached tothe Fifteenth Air Force. Units of enlisted airmen di-rected the killing of adult mosquitoes and flies in thearea, using a 5 per cent. DDT solution in kerosene, apply-ing it with power paint sprayers, hand spray guns andpaintbrushes to prevent the spread of malaria and dis-eases carried by flies. The mixture is applied by two-manteams to military mess halls, kitchens, latrines, andcivilian as well as military sleeping quarters.DDT arrives in Italy in hard, waxy lumps, which are

pulverized in a meat grinder. The solution is made upby adding the pulverized DDT to kerosene and pouringit into five-gallon oil cans. Cans of this mixture arestacked in the sun to hasten solution and are rolled aroundon the ground every twenty-four hours. A good solutionis obtained in about four days.

Spraying teams, after a half-day of schooling inmalaria control, begin applying the poisonous solution towalls, doors and screens of buildings. The men wearprotective masks. These teams also seek out near-bybreeding places of flies and of mosquitoes which mightinfect soldiers with malaria.Some reports indicate that the insecticide did not have

immediate results. However, after several days medicalofficers were convinced of its effectiveness. Observationsshow that areas have to be re-sprayed about every monthor six weeks.According to Major Brother, the results have been

spectacular from the standpoint of pest control, and DDTcan be considered valuable in the prevention of bothmalaria and enteric diseases.-ROBERT N. FARE.

ITEMSA MEMORIAL to be erected in honor of the defenders of

Leningrad will include new buildings for Pulkova Ob-servatory, according to Professor Grigori Neuimin, di-rector of the observatory. Pulkova Heights was one ofthe keypoints in the defense of Leningrad, so it is fittingthat the memorial, which will form an architectural wholewith the observatory buildings, be erected there. Thestaff of Pulkova Observatory, which was evacuated toTashkent, Turkestan, nearly three years ago and con-ducted observations with instruments belonging toTashkent Observatory, is now preparing to return home.Several years will probably be needed, however, to putthe observatory back into shape, although the instrumentswill be in use long before that time, according to theSoviet Information Bureau at Moscow. Part of theobservatory buildings will be restored to their formerappearance, the rest will be modernized.

ALMOST twice as many cases of undulant fever havebeen reported to the U. S. Public Health Service so farthis year as during the corresponding period of 1944.

The total up to February 3 was 354, compared with 184for the same period last year. Undulant fever is alsoknown as Malta fever and brucellosis. It is not oftenfatal but is a long drawn-out sickness, lasting sometimesfor years. The suffering, disability and economic lossare considerable. People get undulant fever, usually,from drinking raw goat's milk or raw cow's milk thatcontains the germs. Pasteurizing milk is a sure safe-guard against undulant fever from this source. Humansmay also get the hog variety of brucellosis, but this isnot very common. Farmers, vegetarians, slaughterhouseemployees, butchers and even cooks can get it fromhandling infected meat or from close contact with in-fected animals. Reporting of cases of undulant fever isnow required in all 48 states and the District of Columbia.Last year, however, was the first in which all states re-ported the disease. It is possible that during this firstyear not all cases were reported while more are beingreported this year. This might account for some the theincrease.

A PARALYSIS that afflicts honeybees, causing wholesaledeath in the hives, has been found to be caused by afilterable virus, just as infantile paralysis in humanbeings is caused by another virus. The bee disease wastraced to its microscopically invisible cause by Dr. C. E.Burnside, of the Bureau of Entomology and Plant Quar-antine. Loss of hair from the bees' bodies, hitherto con-sidered a symptom of honeybee paralysis, was found tobe undependable as a means of diagnosis, for the beesto which he purposely gave the disease in his experimentsdid not become partially naked and shiny. Dr. Burnsideis inclined to believe that loss of hair is not a true symp-tom at all, but is probably due to the tendency of otherbees to bite and pull at the sick ones in an effort to getthem out of the hive. Much more dependable symptoms, hereports, are sprawled legs and wings and a generaltrembling of the whole insect. Now that the disease hasbeen traced to a virus, means of prevention or cure canbe sought for more intelligently, and with greater hopeof ultimate success.

SYNTHETIC rubber now can replace natural rubber inanother field-in the production of chlorinated rubber forship-bottom paints, anti-fouling paints, and non-inflam-mable paints. Chlorinated synthetic rubber can be usedalso in the preparation of sand-core binders for moldingoperations, adhesives and other products. The new syn-thetie chlorinated rubber Is a development of the Good-year Tire and Rubber Company in its laboratories atAkron, Ohio. The new chlorinated synthetic rubber is a

creamy white powder containing from 60 to 70 per cent.chlorine. It is equal to the natural rubber product inevery way, it is claimed. It is soluble in all aromatichydrocarbons, including benzene and toluene, and alsoin esters like ethyl acetate and in chlorinated hydrocar-bons. It is nbn-inflammable, is resistant to both acidaand alkalis and has excellent anti-corrosion qualities.
