MALLERY.] TYPES OF HAND POSITIONS—THEIR USE. 549 
NOTE CONCERNING THE FOREGOING TYPES. 
The positions are given as they appear to an observer facing the 
gesturer, and are designed to show the relations of the fingers to the 
hand rather than the positions of the hand relative to the body, which 
must be shown by the outlines (see OUTLINES OF ARM POSITIONS) or 
description. The right and left hands are figured above without dis- 
crimination, but in description or reference the right hand will be 
understood when the left is not specified. The hands as figured can 
also with proper intimation be applied with changes either upward, 
downward, or inclined to either side, so long as the relative positions 
of the fingers are retained, and when in that respect no one of the types 
exactly corresponds with a sign observed, modifications may be made by 
pen or pencil on that one of the types, or a tracing of it, found most 
convenient, as indicated in the EXAMPLES, and referred to by the letter 
of the alphabet under the type changed, with the addition of a numeral 
—e. g., A1, and if that type, i. e., A, were changed a second time by 
the observer (which change would necessarily be drawn on another 
sheet of types or another tracing of a type selected when there are no 
sheets provided), it should be referred to as A 2.
