Moreover, this element of Ozone in our atmosphere, while of itself most vitally 

 important, is above all valuable as establishing a pure atmosphere, one practically 

 free from organic effluvia, the acknowledged source of malarial disorders. 



But it is obviously entirely beyond either the limits or province of this paper to 

 attempt any consideration of the complex relations of Ozone to health and disease. 

 At some future meeting of this Academy it may perhaps be my privilege to attempt 

 some such discussion. Probably no problem could be mentioned in which tlie 

 opinions maintained by prominent scientists have been so discordant and so chaot- 

 icalljr diverse. Bj^ one class of disputants the veiy possibility is denied of any 

 connection between the. presence of Ozone and the prevalence or absence of certain 

 types of disease. On the other hand, by another party equally eminent it is main- 

 tained that the relations of this element to sanitary conditions are of most vital and 

 paramount importance ; and that it only remains for us to reveal them by careful 

 research. Leading spirits of this latter party have expressed a firm belief in the 

 near proximity of a period of enlightenment, when in addition to piping our dwell- 

 ing-houses for water and gas, we shall not only add an additional pipe for carbonic 

 acid vinder pressure to shield us from the dangers of conflagration, but above all a 

 fourth tube for regulating our domestic atmosphere bj^ a well directed stream of 

 Ozone. Indeed it is only recently that a stock company was organized to this end 

 in the city of Chicago, having as its consulting oracle a well-known western chem- 

 ist, and for its avowed object the manufacture, upon an extended scale, of Ozone for 

 the purification of the private residences, public buildings and sluice-ways and sew- 

 ers of that most odorous city. Unfortunately, however, the efforts of this company 

 prematurely terminated in a prospectus soliciting purchasers of stock ! Enthusiasts 

 in this matter must bear in mind that the presence of an excess of this Ozone is 

 scarcely to be less deplored than its utter absence. It is well known that when 

 existing in the atmosphere in too great an abundance, it occasions attacks of bron- 

 chitis and other bronchial disorders. An explanation has been thus suggested by 

 medical authorities of the prevalence of these diseases, in certain seasons, in noi'th- 

 ern Minnesota. 



What is above all now needed is a general series of careful, patient and conscien- 

 tious observations extending through long periods of years. It is only from such a 

 foundation of well authenticated facts, that we can hope to deduce results of any 

 importance. The investigators of America are now rapidly awakening to the 

 importance of this work. Earnest observers are beginning thorough records in 

 various portions of the United States. It has been my object to call the attention 

 of the gentlemen of this Academy to the importance of organizing a series of care- 

 ful records of the Ozonic phenomena of Kansas. To any one disposed to assist In 

 this work I shall take pleasure in furnishing color scales. Iodized jviper and record
