Probably the most important master's degree introduced in the 19th century was the Master of Science (MS in the US, MSc in the UK). At the University of Michigan this was introduced in two forms in 1858: "in course", first awarded in 1859, and "on examination", first awarded in 1862. The "in course" MS was last awarded in 1876. In Britain, however, the degree took a while longer to arrive. When London introduced its Faculty of Sciences in 1858, the University was granted a new charter giving it the power "to confer the several Degrees of Bachelor, Master, and Doctor, in Arts, Laws, Science, Medicine, Music", but the degrees it awarded in science were the Bachelor of Science and the Doctor of Science. The same two degrees, again omitting the master's, were awarded at Edinburgh, despite the MA being the standard undergraduate degree for Arts in Scotland. In 1862, a Royal Commission suggested that Durham should award master's degrees in theology and science (with the suggested abbreviations MT and MS, contrary to later British practice of using MTh or MTheol and MSc for these degrees), but its recommendations were not enacted. In 1877, Oxford introduced the Master of Natural Science, along with the Bachelor of Natural Science, to stand alongside the MA and BA degrees and be awarded to students who took their degrees in the honours school of natural sciences. In 1879 a statute to actually establish the faculty of Natural Sciences at Oxford was promulgated, but in 1880 a proposal to rename the degree as a Master of Science was rejected along with a proposal to grant Masters of Natural Sciences a Master of Arts degree, in order to make them full members of the University. This scheme would appear to have then been quietly dropped, with Oxford going on to award BAs and MAs in science.
