三牲

三 = 一 + 二 : Mnemonic symbol: a Cartesian coordinate system with three (三) axes.

Socrates (s-) is performing in front of the anthill (-an1). He created an electrical flute by attaching a large capacitor (二) to the flute (一), so that he can get the attention of all the ants. Moreover, he's balancing on a Cartesian coordinate system (三). Unfortunately, only three (三) ants stop to watch the performance.

牲 = 牛 + 生 : The bull (牛) got a child and is watching over it in its cradle (生) in front of the engine ((e)ng1). He has to be very attentive because Sherlock Holmes (sh) wants to use the newborn as a sacrificial animal (牲).
