The nature of Mowbray's patent "consists in combining the glycerine with a mixture previously cooled (consisting of sulphuric acid, six parts, and nitric acid, three parts, to one part of glycerine) by means of centrifugal motion. The advantages of this apparatus are, that the precision of a machine is substituted for the irregularity of hand-labor." (Patent Number 106,606)
