The "Gentleman's magazine" section is a digest of selections from the weekly press; the "(Trader's) monthly intelligencer" section consists of news (foreign and domestic), vital statistics, a register of the month's new publications, and a calendar of forthcoming trade fairs.

Biographies of more than 100 Irish scientists (or those with strong Irish connections), in the disciplines of Chemistry and Physics, including Astronomy, Mathematics etc., describing them in their Irish and international scientific, social, educational and political context. Written in an attractive informal style for the hypothetical 'educated layman' who does not need to have studied science. Well received in Irish and international reviews.
