REPORT OF THE COMMITTEE ON CLIMATOLOGY. The chairman, E. U. Jones, M.D., Taunton, made some extended remarks on ozone. Following is an abstract: Every thing in the air bears a relation to disease. and the action of medicines. Ozone has been known for about forty-two years, and was discovered by Schönbein, who considered it to be peroxide or binoxide of hydrogen, and not an allotropic form of oxygen. He maintained that the amount of electricity in the air influenced its production. Others have regarded ozone as the result of the action of electricity on oxygen. This has not been substantiated it has been found that the slightest trace of hydrogen with oxygen suffices for the production of ozone. Investigation shows that there is but little ozone over cities, probably on account of heat. Sea-air is full of ozone. It is not proved that ozone has a direct causative effect on production of disease. With an increase of ozone, there is a prevalence of certain classes of disease, such as mucous diarrhoea, acute catarrh, bronchitis, muscular rheumatism, etc. In other seasons, when ozone is decreased, we may have dry coughs, serous rheumatisms, acute pleuritis, Ozone may have some influence on the selection of remedies. etc. Dr. N. R. Morse of Salem asked how it can be explained that there is so much ozone in the atmosphere at Taunton, and so little at Boston, near the salt water. Dr. Jones thinks that heat may have something to do with it; also the absence of vegetation in a large city, that being a conservator of ozone. Humidity in the country, arising from the ground, may have some influence. It is possible, too, that ozone may be found in cities, but at a higher altitude.
