Evidence as to document unmeaning in reference to existing facts.

When language used in a document is plain in itself, but is unmeaning in reference to existing facts, evidence may be given to show that it was used in a peculiar sense.

Illustration.

A sells to B, by deed, "my house in Kolkata". A had no house in Kolkata, but it appears that he had a house at Howrah, of which B had been in possession since the execution of the deed. These facts may be proved to show that the deed related to the house at Howrah.
