The result, of course, would be the same where the parties, knowing the full facts, fraudulently clothe the transaction in the garb of a an out and out sale of the property, and there is, no erroneous representation made by the transferor to the transferor as, to his, ownership. "But where an erroneous, representation is, made by the transferor to the transferee that he is, the full owner of the property transferred and is authorized to transfer it and the property transferred is not a mere chance of succession but immovable property itself, and the transferee acts, upon such erroneous representation, then if the transferor happens, later, before the contract of transfer comes, to an end, to acquire an interest in that property, no matter whether by private purchase, gift, legacy or by inheritance or otherwise, the previous transfer can at the option of the transferee operate on the interest which has, been subsequently acquired, although it did not exit at the time of the transfer." (pp. 478,479).
