It is not necessary to quote further. In order to insure that everyone will recognize the great need of Kalak it is advised to test the urine for acidity by means of a group of indicator solutions sent out to the physicians. Methyl red is one of these and any urine showing an acid reaction with this is said to be open to suspicion. Paranitrophenol is another of the indicators and the explanations given of the behavior of the two and the conclusions to be drawn are questionable. The methyl red solution furnished is too concentrated for proper use and perfectly normal urines from normal individuals have given a rather marked color with it. This indicator gives some color at [H+] = 1.2 × 10^{-6} and a strong reaction at 3 × 10^{-3}. To condemn a urine on such a finding is entirely unwarranted. Sodium bicarbonate is the main constituent of the water. The value of the phosphate in such a combination, with so much calcium, is problematical. In case an alkaline reaction in the intestine is reached some of it would be left as insoluble phosphate. A few grams of bicarbonate daily would have equal therapeutic value with this water. The advice based on the indications of methyl red and the urine is bad. The committee’s report was sent to the Kalak Water Company for comment. The company promised to withdraw the advertising circular referred to in the report and disclaimed responsibility for the accuracy and value of the set of indicators which it sent out, but, on the whole, the previous advertising claims were insisted on. In view of the absurd and false claims made for the product the Council declared Kalak Water inadmissible to N. N. R.--(_From Reports of Council on Pharmacy and Chemistry, 1917, p. 148._) MINSON’S SOLUBLE IODIN “KELPIDINE” NOT ADMITTED TO N. N. R. Report of the Council on Pharmacy and Chemistry Minson’s Soluble Iodin “Kelpidine” was submitted to the Council by J. J. Minson, Washington, D. C., trading as the Kelpidine Company, with the statement that in future “literature” it was to be known as Minson’s Soluble Iodin, only. The following statement of composition was furnished: “Minson’s Soluble Iodin is somewhat of an indefinite character, chemically. Its formula is, Iodin 4 per cent., Distilled Water 6 per cent., and Absolute Alcohol _q. s._ 100 per cent. By a process of chilling and heating an iodid of uncertain character is produced, and because of the extreme sensitiveness of the product to chemical tests, it is hard to determine. So far as I have been able to judge, however, the result is about 3 or 3-1/2 per cent. free iodin and from 1/2 per cent. to 1 per cent. iodid, possibly ethyl and hydrogen iodid in combination.” The A. M. A. Chemical Laboratory reports that the preparation is an alcoholic solution containing free iodin and iodid, probably hydrogen iodid and ethyl iodid, but that the free iodin content was only 2.69 gm. per 100 c.c.
