from
Bouvier's Law Dictionary, Revised 6th Ed (1856)
ACCUMULATIVE JUDGMENT. A second or additional judgment given against one,
who has been convicted, the execution or effect of which is to commence
after the first has expired; as, where a man is sentenced to an imprisonment
for six months on conviction of larceny, and, afterwards he is convicted of
burglary, he may be sentenced to undergo an imprisonment for the latter
crime, to commence after the expiration of the first imprisonment; this is
called an accumulative judgment.
