Reading edition
This property distinguishes it from the Mowbray Tri-Nitro-Glycerin, the latter contracting about one-twelfth of its bulk in congealing; further, the Nobel patents claim a preparation which congeals at 55°F, whereas the Mowbray Tri-Nitro-Glycerin congeals at 45°F. No further evidence is necessary to prove that a real difference of component parts exists between the two preparations.
