1. Luis Seabra Lopes did a statistical study of reported values for the alqueire in the 19th century, and found they fell into 7 groups. They are not necessarily province-specific; that is, in some provinces several different standards were in use. Group A includes the equivalence determined by the Academia das Ciências de Lisboa, 13.197 liters for the alqueire. According to Professor Seabra Lopes, the most frequently encountered values fell into groups B (24.3%) and D (24.9%).

2. The equivalences reported by Doursther and Nelkenbracher are provided as examples of 19th-century commercial values. Nelkenbrecher (page 545) treats selamin as a synonym for outava.
