Section 195 Valuation by reference to other interests.

If in determining the value on death of any interest to which the claim relates, any other interests, whether in the same or other land, were taken into account, an addition shall be made to the sale price of the interest; and the amount of the addition shall be equal to the difference between the value on death of the interest and the value which would have been the value on death if no other interests had been taken into account.
