Table des Monnaies, Poids et Mesures en usage a Guernesey, published by Frederick Clarke
In the mid-19th century Frederick Clarke produced in his establishment in the States Arcade this little booklet, attempting to distil in four pages the labyrinthine system of weights and measures at that time employed in the island. Its difficulty was compounded by the sheer number of currencies that island merchants and traders had to deal with. The information is taken literally from schoolmaster Thomas du Frocq's Nouveau Precepteur of 1818, which is a (mainly) applied mathematics primer of tortuous complexity and much greater length.
