Not clear whether this experiment was carried out or only planned:
 
Dissolved 94 g of crystallized ADP in 117 g H2O at 60 C forming a saturated solution.

On cooling to 38 C, 54 g crystallized (A14); saturation should be 52.3 g/dL.

On cooling to 34 C, 25 g crystallized (A16); saturation should be 48.3 g/dL.

On cooling at 29 C, 15 g crystallized (A18); saturation should be 43.9 g/dL.
