legal document dated 3rd May 1765 between Peter Dollond & John Bridge for the sum of £500.00 Footnote: These bonds were connected with another deed drawn up on the same date, and were used to make sure that the covenants referred to in the deed were kept to - for instance, building a house to a particular specification, or producing title deeds on request. The covenants themselves are not repeated in the bond, so the deed needs to be present in order to make sense of this type of bond.
