Usage examples of "solvitur".
It was as though those who had insisted on the derivation of all forms of the steam-engine from the common kettle, and who saw that this stands in much the same relations to the engines, we will say, of the Great Eastern steamship as the amœba to man, were to declare that the Great Eastern engines were not designed at all, on the ground that no one in the early kettle days had foreseen so great a future development, and were unable to understand that a piecemeal solvitur ambulando design is more omnipresent, all-seeing, and all-searching, and hence more truly in the strictest sense design, than any speculative leap of fancy, however bold and even at times successful.
