He is sure that Linnaeus accepted the former student, and he hopes that Linnaeus will take similar care of his son and help him to reach the goal of his studies. It is not yet decided if his son will study theology or medicine, but whichever he chooses, it would be a great help and favour for him to have Linnaeus as his tutor [Johan Christian Petersen von Heidenstam studied medicine under Linnaeus and in 1758 pro exercitio defended the dissertation, Dissertatio de cortice PeruvianoLinnaeus, Carl Dissertatio de
