In 1865 the Great Hall was enlarged by the architect David Bryce, who ordered the roundel portraits from George MacCallum. MacCallum was paid four pounds per profile, a total of £60 for the set of 15 ‘Heads with wreaths’.

The portraits appear along the frieze in the Great Hall. Each of the figures in the roundel portraits is surrounded by a laurel wreath which is both an aesthetic, decorative feature, and a classical symbol which emphasises the importance of the figure depicted in the portrait. Smellie is portrayed simply with the greatest amount of detailing seen in the depiction of his wig.

William Smellie (1697 – 1763)

William Smellie is particularly significant for his contribution to midwifery. By 1722 he was an independent apothecary in Lanark during which time he also gained experience in midwifery through assisting local midwives with complicated births. By 1737 he was focussing on midwifery and his main techniques were craniotomy and turning the child. He received his MD from Glasgow University in 1745. Thereafter his career was based in London where he worked as a teacher to both male and female students of midwifery. As part of his teaching he brought students to observe the cases of poor women, who in return were not charged any fees for their medical care during pregnancy.

In 1752 Smellie published A Treatise of the Theory and Practice of Midwifery (three volumes 1752 – 1764) and, 1754 A Set of Anatomical Tables, with Explanations. This work became significant in obstetric literature, advancing the practice considerably, and was translated into French, German and Dutch.
