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
Clearflight Pied budgerigar mutation over half the body area affected, although the clear areas in cocks tend to be larger than those of hens. The Clearflight Pied gene is located on one of the autosomal chromosomes. There is no known linkage of this gene with any other mutation. There is no universally accepted genetic symbol for either the locus or mutant allele, so the symbol "Pc" for 'Pied, clearflight' will be adopted here for the wild-type allele at this locus, and the symbol "Pc" for the Clearflight Pied mutant allele. Both Taylor and Warner and Martin used just "P" for the Clearflight Pied locus,
