No branch of science appeals to us so deeply as the study of life; and it is the object of the following research to investigate some of the causes which tend to shorten life, and if possible to devise means of detecting these causes before they have produced permanent injury to the individual.
In presenting the subject I feel very keenly my inability to do it the justice which it deserves. But realizing that success is achieved in any line of research only after repeated efforts, and often after many failures, I am encouraged in the undertaking, believing that the closer we adhere to nature, the nearer we shall arrive at the truth. Also I regret that the limited time which is necessarily allowed for the presentation of the subject, prevents my giving proper credit to many authorities whose researches have rendered me valuable assistance in forming the following deductions.
