 The university 's second college , Hatfield Hall , was formed in 1846 as a response to the high costs of maintaining Castle . These costs arose from the students ' expectations of being provided with servants and room furnishings . The university struggled for the rest of the 19th century , held back by a lack of prestige and a distance from the centres of power in the UK . By 1882 , Castle contained some 79 undergraduates out of 205 at the university as a whole . Despite the university largely failing to gain recognition and prestige , a number of other colleges had opened by the end of the nineteenth century . Of these , Cosin 's Hall failed to become financially viable and was absorbed into University College in 1864 . Enrolment numbers continued to fluctuate .
