The second figure measures the daytime arches. Originally prepared in French by Abbot M. Pluche and translated into Castilian Spanish. Engraved by Jose Andrade for publication in Volume VII, Part 4 of D. Gabriel Ramirez's Espectaculo de la Naturaleza, O Conversaciones a Cerca de Las Particularidades de la Historia Natural.
