 The Masonic signs Holmes makes to the Chief Inspector are: the  Duegard of the Entered Apprentice (right hand palm down over left  hand palm up), the Sign of the Entered Apprentice (drawing the right  hand from left to right across the throat), a variation of the Real  Grip of a Master Mason(the handshake with the thumb and little  finger extended), and finally the Sign of a Fellow Craft (drawing  the right hand across the body from the left breast to the right  hip). The Signs all refer to the penalties associated with the  divulging of the Orders secrets to outsiders, i.e., having the  throat slit and the chest opened and the heart torn out. The Duegard  refers to the gesture of holding the Bible during the initiation  ritual in the left hand, with the right resting upon it.
