Final answer:
The university referenced as serving Devonshire cream is not specifically mentioned in the context provided. Both Oxford and Cambridge have long histories that could suggest pastoral features like a farm on their campuses. Without direct evidence, the specific British university cannot be identified.
Step-by-step explanation:
In the 1820s, the British university campus that was once a farm and served Devonshire cream to strollers is not specifically mentioned in the historic facts provided. However, by considering the two British universities mentioned, Oxford and Cambridge, one might infer that either could have had such pastoral features in the 1820s, given their long histories and extensive campuses. Nonetheless, without direct historical evidence regarding the Devonshire cream tradition, one cannot definitively answer the student's question with the information provided.
Nevertheless, it is well-established that in the early modern era, prestigious universities like Oxford and Cambridge existed primarily to train privileged male students for careers in civil service or fields like medicine, law, or theology. The curriculum at that time tended to uphold tradition over innovation, although connections with wealthy patrons could sometimes finance more innovative research outside of the university setting.
