Units of measurement in France before the French Revolution (league) had a number of variations, particularly the "aune" (which was used to measure cloth The "loi du 19 frimaire an VIII" (Law of 10 December 1799) states that one decimal metre is exactly 443.296 French lines, or "3 pieds 11.296 lignes de la "Toise du Pérou"". Thus the French royal foot is exactly 9000/27,706 metres (about 0.3248 m). In Quebec, the surveys in French units were converted using the relationship 1 "pied" (of the French variety, the same word being used for English feet as well) = 12.789 English inches. This makes the Quebec "pied" very slightly smaller (about
Pied tamarin the pied tamarin from areas of its historical distribution. There are therefore multiple threats to the long-term survival off the pied tamarin that stem from habitat destruction and from interspecific competition. The pied tamarin's body measures 20.8–28.3 cm.; including the tail it measures 33.5–42.0 cm. Males weigh 428 grams ("n" = 4). Its life expectancy is approximately 10 years in the wild. Individuals live in groups of 2 to 15 members with little intra-group competition. Average group size in the Reserva Florestal Adolpho Ducke is 4.8 individuals per group ("n" = 41), and other areas around Manaus reported mean group
