At the suggestion of the author in the Maternity Department of the Transcaucasian Midwife Institute since 1887, the following method of caring for the umbilical cord has been used: 1) bandaging the umbilical cord with an antiseptic paper or silk cord (preserved after an hour of boiling in an aqueous solution of mercuric chloride 1: 500 in alcohol 1: 500. 1000): 2) washing the remainder of the umbilical cord with a 21/2% solution. carbolic acid, wrapped in absorbent cotton wool (the remainder is then placed on the left side of the abdomen, covered with carbolic acid gauze, with two layers of plain cotton wool and bandaged).

Mercury Poisoning

Polyvinyl alcohol preservative (PVA) is used routinely in the laboratory for collection of specimens for examination for ova and parasites.1-4 PVA, presently used at Harbor-UCLA Medical Center, contains: 4.5% mercuric chloride, 5% polyvinyl alcohol, 30% denatured alcohol, 4.5% acetic acid, and 1.5% glycerin in an aqueous solution. The kit, as shown in the Figure, contains three bottles with 10-ml aliquots of PVA, wooden sticks for mixing the specimen, and written instructions for collection of the specimens. The bottles are clearly labeled as poison in English and Spanish, and specific verbal as well as written instructions are given to patients and their families when the ova and parasite kits are dispensed.

The One

The widespread use of the antiseptic or anti-rotting method in the last 20 years, which has yielded brilliant results both in general surgery, and especially in the surgical treatment of diseases of the abdominal and pelvic organs, also has its disadvantages, the main one of which undoubtedly should be considered poisoning when using various anti-rotting medicines. In the literature there is already a rich casuistic material of deadly poisoning when used as an anesthetic, iodoform, carbolic acid, mercuric chloride, etc., etc. antiseptics or antiseptic method of treatment, despite the quick and brilliant success, still left much to be desired and made, during this entire 20-year period, both in laboratory and at the bedside of the patient, to look for means to disinfect the wound, with on the one hand, and not having a harmful effect on patients and those around them, on the other. Carbolic acid was replaced by iodine preparations, iodine preparations with mercuric chloride preparations, mercuric chloride boric acid, copper sulfate, creolin, lysol and many others, some of which have already been abandoned, some are still being tested. The degree of concentration of solutions changed, the time of their contact with the early was limited, and nevertheless, cases of poisoning, which, however, became less common, nevertheless did occur.

Final Yield

It is shown that the reaction of formaldehyde with an ammonium salt to form hexamine is general. The rate of formation and the final yield of hexamine vary greatly with the different ammonium salts, being greater in the solutions of higher pH. When buffered at given pH, the various ammonium salts give approximately the same rates of formation and final yields of hexamine. Rate curves have been determined for the reaction of formaldehyde with ammonium nitrate in aqueous solutions buffered at pH 8.0, 6.0, and 4.0, at temperatures of 0°, 20°, and 40 °C. and over a range of initial mole ratios (formaldehyde: ammonium nitrate) of 0.75 to 3.0. For each set of conditions, three rate curves have been obtained on the basis of ammonia consumed, formaldehyde consumed, and material precipitated with mercuric chloride. In excess formaldehyde, it appears that a stable by-product is formed; its formation increases as the temperature is increased. In excess ammonium nitrate, by-product formation is decreased. A mechanism of hexamine formation is suggested in accordance with the data.

Negative Viscosity

In a recent paper published by the authors, some measurements of the viscosity of aqueous solutions indicated that it would be of interest to investigate more fully the viscosity of solutions, especially those which exhibit what is now generally known as “negative viscosity,” over a wider range of temperature.This has now been done to a certain extent, and to enable a comparison to be made between electrolytes and non-electrolytes in aqueous solution, some other substances have been included in the investigation. They are:—potassium chloride, potassium chlorate, ammonium iodide, potassium ferricyanide, potassium ferrocyanide; mercuric chloride, mercuric cyanide; carbamide.
