THE FIRST PART XV
Having already discussed the proportion of the hands, I will only show a sketch here for figure A. In the same problem, you can easily find how the hand turns and changes, as the figures B C D also demonstrate. Because once the charcoal is erased, the fingers form into the squares without much trouble, and sometimes the figures lengthen or shorten because the fingers extend or bend.
In Dutch: Having adequately measured the hands, I do not wish to show anything now beyond the draft; figure A (in the same display) and how you can easily find how the hands change and flex; just like figures B C D. And with charcoal, the fingers can be positioned in the square without much effort; sometimes the figures lengthen and shorten due to the bending and stretching of the fingers.
In French: Having mentioned the proportion of the hand sufficiently, I do not wish to demonstrate anything here except the sketch, marked by letter A. In the same problem, you will easily find how the hands change and bend, as does figure B, C, D. And having pointed with charcoal, the fingers form in the square without much effort. Sometimes the figures lengthen or shorten, as the fingers extend or bend.
In German: I have already indicated the measure of the hands; so now I will show nothing else, than simply the draft of figure A / in the same representation, you will easily find how the hands should be turned and twisted, as also in figures B C D. Once drawn with charcoal, the fingers will easily set themselves in the square; sometimes the figures lengthen and shorten as the fingers bend or extend.
