Such assent may be express or implied, and may by given either before or after the appropriation is made.

   Delivery to carrier.—(2)  Where, in pursuance of the contract, the seller delivers the goods to the buyer or to a carrier or other bailee (whether named by the buyer or not) for the purpose of transmission to the buyer, and does not reserve the right of disposal, he is deemed to have unconditionally appropriated the goods to the contract.
