The space between two veins is called an intervenÃum; this interval
between the veins, if it is between venae dilatatae is entirely hidden underÂ

Venae profundae differ
greatly one from another in width, for some of
them are one fathom wide, some are two cubits, others one cubit; others again
are a foot wide, and some only half a foot; all of which our miners call wide
veins. Others on the contrary, are only a palm wide, others three digits,
