Note on the foundation of Queen Charlotte's Hospital.

One must presume that Schoener derived two more crases in the same way: 'dry' with 'hot' and 'cold' balanced, and 'moist' with 'hot' and 'cold' balanced. In his opinion the yield was then eight combined crases, plus four simple crases and the eucrasic state in which 'hot' and 'cold', and 'warm' and 'moist' were equally balanced. But it should be obvious that in the simple crasis 'hot' (where 'hot' predominates over 'cold') 'moist' and 'dry' must be in balance, and so on for the remaining simple crases. Thus there can be only four combined and four simple crases in addition to the eucrasic state. The matter is clearly explained by Galen in Chapter VIII of Book 1 On Crases (Kuehn I, pp. 554-59). He says that the four combined dyscrasias, 'hot' and 'moist', 'hot' and 'dry', 'cold' and 'moist', and 'cold' and 'dry' are well known to physicians and philosophers but they have neglected the 'first and best' of the crases-eucrasis, where 'hot' and 'cold', and 'moist' and 'dry' are in balance-as well as the remaining four, which are constituted, he says, by 'half' of the combined dyscrasias. In justifying the existence of the last four Galen states that when 'hot' predominates over 'cold' it is not necessary that either 'dry' or 'moist' predominate as well; they may be in balance. And so on for the remaining qualities. This being the case, Galen concludes, we have no reason to doubt that there are nine crases (ennea tas pasas einai ton krase3n
