For purposes of abatement, a general devise charged on any specific property or fund is a specific devise to the extent of the value of the property on which it is charged, and upon the failure or insufficiency of the property on which it is charged, a general devise to the extent of the failure or insufficiency. Abatement within each classification is in proportion to the value of property each of the beneficiaries would have received if full distribution of the property had been made in accordance with the terms of the will.
