The word hereof is actually not a legal term. Its meaning in court documents is no different from its ordinary dictionary definition -- Merriam-Webester defines hereof as meaning of this.. It's one of those words used by lawyers and nobody else.
The variety of cabbage commonly known as the Flat Dutch, shown in Fig. 6, of which there are many strains, is a moderately long-season variety. The head is very solid and flat; it measures about 12 inches across and 8 inches deep, and weighs from 8 to 12 pounds.
Cabbage sizes can be as small as a softball or as big as a basketball. Specifically, these would have measurements of around 1 to 2 kg or 2 to 3 kg. The appearance of the red cabbage is similar to the green cabbage except, of course, for its color. In size, it is smaller, but also tightly packed and fresh-looking.
