For purposes of abatement, a demonstrative devise of money or property payable out of or charged on a particular fund or other property is treated as a specific devise; but if the particular fund or property out of which the demonstrative devise is to be paid is nonexistent or insufficient at the death of the testator, the deficiency is to be payable out of the general estate of the decedent and is to be regarded as a general devise and must abate pro rata with other general devises. Abatement within each classification is in proportion to the amounts of property each of the beneficiaries would have received, had full distribution of the property been made in accordance with the terms of the will.
