A more thorough explanation:

MOLITURAE

Moliturae is a term used in Scots law to refer to tolls or fees paid for grinding grain. It is also known as multures. When used in the phrase "cum astrictis multuris," it refers to defined payments for grinding with astricted multures. This means that the landholder is bound to pay a certain mill a specific portion of the grain in exchange for grinding the rest of it.

An example of moliturae would be a farmer taking their grain to a mill to be ground into flour. The miller would charge a fee for this service, which is the moliturae. Another example would be a landowner who is required to pay a certain amount of grain to a specific mill in exchange for grinding the rest of their grain.

When used in the phrase "cum astrictis multuris," an example would be a landowner who is required to pay a specific amount of grain to a mill for grinding, rather than negotiating the fee each time they bring their grain to the mill. This ensures that the landowner knows exactly how much they will have to pay for the service each time.

These examples illustrate how moliturae and cum astrictis multuris were used in Scots law to regulate the fees paid for grinding grain. They show how the landowner and miller would negotiate the terms of the agreement, and how the landowner would be bound to pay a specific amount of grain to the mill for grinding.
