This article describes a custom-designed 'garden' sundial commissioned as a 40th birthday gift for Campbell Forsyth of Faversham. It is an inclining horizontal dial for latitude 40°N, tilted 11.5° southwards, with a unique gilded 'box' feature that indicates the exact date and time (8 December, 12 noon) on his birthday. The dial is a work of scientific art by Ben Jones, with a pedestal by Clive Sherwood.

This article describes a collection of miniature crested 'Goss' china sundial ornaments produced from the 1880s. These decorative horizontal dials, typically featuring local heraldic arms, were collected as souvenirs and are now considered rare treasures, despite often having incorrect hour-line delineations.

This historical essay details the Meridies Media sundial designed by Dr Tadeusz Przypkowski for the Old Royal Observatory at Greenwich in 1967. It describes the dial's function using an analemma to indicate standard mean time, true noon, and date. The article recounts the author's involvement in its installation, the initial design error, and the eventual reconstruction of the wooden dial in 1969, which remained until 1991.

This article recounts the theft and subsequent recovery of a brass horizontal sundial by George Adams Jnr from Belmont House. A BSS member, Andrew James, identified the stolen dial on a dealer's website, leading to its return. The piece highlights the crucial value of the BSS Register and members' expertise in recovering stolen historical dials.

A short, light-hearted poem likening the dandelion flower and seed head to a natural sundial, marking sunny hours by its bloom and dispersal of seeds.
Mottoes

This article traces the history and invention of the analemma, a 'figure-of-eight' shaped curve that corrects for the equation of time on a sundial. It discusses the contributions of Jean-Paul Grandjean de Fouchy and Johann Philipp von Wurzelbau, and notes that the analemma first appeared in English publications in 1889.
Equation of Time

This part of the article discusses the history and application of the analemma in equinoctial sundials, particularly in Great Britain and the Netherlands. It details inventions by Major-General John Ryder Oliver, William Pilkington, and William Homan, and provides strong evidence suggesting Johann Philipp von Wurzelbau invented the analemma around 1716, predating Jean-Paul Grandjean de Fouchy.

The Chairman reflects on the importance of acknowledging errors in the field of dialling and maintaining high standards within the British Sundial Society. He shares personal anecdotes of past mistakes and discusses common misconceptions about sundials, such as their role in timekeeping, reasons for their decline, and the historical evolution of their appearance, emphasizing the need for accuracy and critical examination.

The chairman discusses the British sundial heritage, noting its rapid decline due to neglect and vandalism. He emphasizes the importance of the Society's ongoing work to catalogue, record, and research sundials in Britain for their preservation and restoration. He also cautions members about offering restoration advice without professional expertise and highlights the need to identify outstanding sundials for national protection.

This lecture explores the practical aspects of 16th and 17th-century navigation, highlighting the crucial role of sundials and similar instruments for determining time at sea. Mariners used celestial observations for latitude, magnetic compasses for direction, and various tools like traverse boards, sand-glasses, nocturnals, astrolabes, and cross-staves for navigation and timekeeping.

This article describes 18th-century slate sundials at Tawstock and Marwood churches by John Berry, the Tawstock dial being notable for its "domifying circles" or "circles of position". Berry, a local stonemason probably had help from a Cambridge don in laying out these sophisticated dials. These unusual domus lines indicate which astrological (rather than astronomical) zodiacal house the sun is in. The dial also features zodiacal signs, time of noon in various places, azimuth lines, and diurnal arcs for day length.

Christopher St. J.H. Daniel discusses the significance and selection of emblems for scientific societies, using nautical examples. He explains why the British Sundial Society chose the equinoctial sundial as its emblem, symbolizing gnomonics and its fundamental role in dialling. Despite some member criticism, the equinoctial dial design is deemed simple, clear, and representative of the art's ancient origins and scientific principles.
