DANGERS OF WIRELESS.

The latest in the list of occupational maladies is "wireless operators'. disease." A German authority says: — "Wireless telegraphers are subject to anaemia,' in which the number of red globules, as well as their content of haemoglobin, is diminished. This malady has certainly various causes; in the first place, the defective sanitary conditions of the stations, especially on board ship. It is equally probable thai the strong ozonisation of the air, due t6 the use of alternate ing currents of high frequency'to send the ihetsages, plays an important part. Similar'troubles, such as paleness, headache, loss of appetite, and bad digestion, have often been noted among the electrical workers employed in high-tension plants,' such as those at Niagara. The future will show us whether electric waves have any physiological effects. A Viennese physician, Dr Beer, has noted the production of subjective glows when a powerful electro-magnet is brought near the head. . . . . An Ameri-

can electrical engineer named Collins has made experiments on a sleeping cat, and asserts that, underthe influence of electric waves the animal leapt into the air as if an alternating current had been sent through it. Collins concludes tEat powerful electric waves may cause characteristic accidents, possibly fatal ones. Nevertheless, no absolutely conclusive proofs have yet been obtained."
