The apparatus employed in the intravenous drip is packed and autoclaved in a special container, devised by Dr. Joseph Turner, director of the Mount Sinai Hospital. The feature of this box is a slot containing perforations which are open while in the autoclave and closed at all other times to prevent contamination.
Each set consists of a gravity flask and two lengths of translucent rubber tubing connected by a Murphy drip. The longer strip of tubing is attached to the gravity flask; the shorter, to an adaptor which fits a standard 20 gage, 1½ inch (3.8 cm.) needle.
The drugs are dissolved in a solution of triple-distilled water containing 5 per cent dextrose. Because of instability, the neoarsphenamine solutions were made up at hourly intervals, as has been previously described. In the present work, the content of an ampule containing 60 mg. of mapharsen has been dissolved in 600 cc.
