RAMC history extract - In 1857 the Medical Staff Corps was reorganised into the Army Hospital Corps, although it reverted back to its former name in 1884 and by 1898 there were two distinct organisations within the Army Medical Services, the Medical Staff Corps and the Medical Staff (i.e. the officers). These two separate organisations were reorganised into one Corps, the Royal Army Medical Corps, by Royal Warrant on 23rd June 1898.
Almost certainly the Militia Medical Staff Corps, the part time Medical Staff Corps, there are a number of them in Aldershot.
From a history of the militia:
The militia reserve consisted of men selected from the ranks of the militia for special enlistment for service in the regular army when called upon in emergencies, in the following proportions to the establishments of the various corps: — Artillery, one-third ; engineers and infantry, one-fourth; medical staff corps, one-half. Special regulations are made as to age, physique, and character. The militia reserve was first formed in 1867, and in 1900 numbered 30,000 men. During an emergency in 1878, 20,000 militia reservists joined the regular army. The term "militia" reserve is therefore a complete misnomer, and the force so called is purely an army reserve.
