My words run:—It must not escape notice in experiments of the nature under consideration, that the state of the bladder, as regards fullness or emptiness at the time of the injection, will form an important factor in determining the character of the result obtained, by influencing the extent to which the urine secreted after the injection is diluted by that previously existing.” I dispute the truthfulness of the assertion that the observations of Seegen on diabetes, if the observa- tions are looked at as a whole, are opposed to the conclusion. They are to be found at p. 237 of his ‘ Glycogeuie Animate.’ There are irregularities un- doubtedly visible in the table given but it must also be said that these irregularities on being looked into are of a nature to cast the gravest suspicion upon the intrinsic correctness of the results with which they are connected. In disagreement with modern ac- credited authority, Seegen places the amount of sugar present under normal circumstances in the blood as high as 1-7 per 1000. He admits that in diabetes a close relationship exists between sugar in the urine and carbohydrate matter in the food. How is this relationship to exist except through the medium of the blood ?
