   <dcterms:abstract>We present several ruler and compass practical geometric constructions that can be performed in the lemniscate curve. To be precise, we provide recipes for halv- ing, doubling, adding, subtracting, and transferring lemniscate arcs with ruler and compass. This note complements the instructions for the lemnatomic equilat- eral triangle and pentagon discussed in a previous paper, giving the details for the construction of the lemnatomic regular 17-gon</dcterms:abstract>
