;                                 Solution 2 was prepared as a well solution and
                                  mixed. A droplet containing 2 \ml of solution
                                  1 was delivered onto a cover slip; 2 \ml of
                                  solution 2 was added to the droplet without
                                  mixing.

;                                 Crystal plates were originally stored at room
                                  temperature for 1 week but no nucleation
                                  occurred. They were then transferred to 4
                                  degrees C, at which temperature well formed
                                  single crystals grew in 2 days.

                                  growth is very sharp. At pH 7.4 only showers
                                  of tiny crystals grew, at pH 7.5 well formed
                                  single crystals grew, at pH 7.6 no
                                  crystallization occurred at all.
