PARALLELEPIPED SHAPED MOLECULAR CRYSTALS
1  HAVE 2 FACES THAT ARE PARALLELOGRAMS  2. HAVE 2 PAIRS OF PARALLEL SIDES      THAT ARE PERPENDICULAR      TO THE FOUR PARALLEL EDGES OF THE PARALLELOGRAM. ( MONO-CLINIC....SINGLE INCLINE....IS THE FORMER NAME FOR THESE CRYSTALS )
A PARALLELPIPED CRYSTAL	A VIEW OF THE SIDE & TOP
HERE YOU SEE THAT THE CRYSTAL HAS AN INCLINE OR SLOPE THEREFORE IT WAS CALLLED  MONO-CLINIC ( ONE INCLINE )	HERE YOU SEE THAT IN THIS DIRECTION THE CRYSTAL IS PERPENDICULAR TO THE TABLE TOP
1. THE PARALLELPIPED CRYSTALS ARE FOUND IN ANODIC       iDEPOSITS OF THE ELECTRICITY CONDUCTING METALS    2. A FEW QUARTZ TYPE VERY TRANSPARENT MINERALS        MAKE PARALLELPIPED CRYSTALS ABOUT 10 CM. LONG    3. VERY FEW COMPOUNDS HAVE MONO-CLINIC, PARALLELEPIPED        CRYSTALS OTHER THAN THOSE USED TO MAKE AMALGAMS
