The mother who puts drops in her child 's nose, or sprays it to relieve a icold, may inadvertently give him pneumonia or other serious lung trouble. So may the lay person who uses a eertain typo of nose spray, or drops for his own cold. This danger was pointed out by Dr. Paul E. Cannon,. of the TJniversity of Chicago, before the Federation of American Societies for Experimental Biology. Ho and Dr. Theodore Walsh found in animal studies that the oil of sprays and drops may get into the lungs, frequently causing edema, or watery swelling, and pneumonia. The partieular kind of nose sprays which Dr. •Cannon warned against are those in which the medicinal substanees are dis-. solved in light oils. Mineral oils are used in many of the preparations beeause they keep better than plant oils. Plant oils, however, are safer, beeause if they do get into the lungs the tissues can dispose of them. If these sprays and drops' are used expertly, as .by. a physician, there is probably little danger. It is their indiscriminate use by tho untrained person that may cause serious trouble.
