A survey is given of a set of five theories, which can be applied to crystal growth from solution. These theories are (I) the morphological theory of Hartman and Perdok, (II) statistical mechanical surface theories, (III) computer simulation models, (IV) in conjuction with two dimensional nucleation theories and (V) the BCF step models. Using reasonable presuppositions it can be shown that these theories are compatible with each other. The loosely coupled network of theories should be confronted with coupled experiments concerning (i) accurate measurements of rates versus supersaturation, (ii) observation of step propagation over crystal surfaces, (iii) observations of dislocations and (iv) morphological data. Although progress has been made, critical experimental tests of the theories for crystal growth from solutions have not yet been carried out.
