In 1918, the constituency was largely replaced by two new county constituencies. The Western Isles constituency was created to cover Outer Hebridean areas of the county of Inverness, as well as part of the county of Ross and Cromarty. The Inverness constituency was created to cover the rest of the county of Inverness, including the parliamentary burgh.
The original electorate for this constituency was limited to substantial landowners. The 40 shilling freehold qualification used for English county constituencies, which was not adjusted for inflation since it was first set in the 15th century, was significantly lower than the Scottish county qualification. In Scotland the qualification was land worth 40 shillings "of old extent", which prevented inflation lowering the real value of the property qualification required.
The county electorate, in Scotland, was significantly extended in 1832 and was further expanded in 1868 and 1885. The change, before and after 1832, can be seen by comparing the 32 votes cast at the contested election in 1802 with the 467 votes cast in 1832 (when the new registration system recorded a registered electorate of 669).
Unless otherwise indicated, the primary source for the results listed was Craig. Candidates identified by Craig as Conservatives, in the 1832-1835 Parliament, are listed as Tories. In elections before the formal creation of the Liberal Party, shortly after the 1859 general election, candidates identified by Craig as Liberals are classified as Whigs. There were no Radicals candidates in this seat, according to Stooks Smith. Craig's registered electorate and vote figures are sometimes different from those of Stooks Smith, but Craig's figures are used below. For details of the books of Craig and Stooks Smith, see the Reference section below.
The calculations of change in% vote and swing, for the 1835 general election result, relate the performance of the Conservative candidate to his achievements as the Tory candidate in the 1832 general election.
