Thus, despite much effort, no gelling agent has yet been discovered that possesses all the properties and benefits of agar. Agar continues to be the best all-arounder: versatile, cheap, and established. And, if Gelidium agar should ever run out, and another colloid is not at hand, microbiologists could revert to culinary agar, which, although not as pure and transparent, offers a low-cost alternative to lab-grade agar.
书中穿插了不少诙谐故事、民俗谚语，调和了学术理论的严谨与抽象。譬如“韩延寿巧断争田案”中的“县官误解风土”，某郡太守向一县官问话：“此地风土如何？”县官不知道“风土”指的是风俗习惯，于是答道：“风不大，土沙也不乱飞。”太守又问：“黎庶还好吗？”县官更不懂“黎庶”指的是老百姓，回答说：“梨树今年开花少，估计要减产。”看似闲笔，实则暗合执法施政必须考察风土民情的道理，让读者在会心一笑中领会中华法系的吏治知识。
