'Abyssum duplicatum cum Hyrogliphis', illustrated by a few pen-drawings of alchemical apparatus, and 14 water-colour symbolic figures from the 'Viridarium chymicum' of Daniel Stolcius, published at Frankfurt in 1624. The contents of Volume I seem to be a transcript of Anton Joseph Kirchweger's 'Aurea catena Homeri', the title of which, beginning 'Eine Beschreibung von dem Ursprung der Natur [etc.]', is found on the third leaf. This work was first published at Leipzig in 1723 [cf. Ferguson, 'Bibliotheca Chemica', Volume I, pp. 469-471]. The second volume is concerned with the 'Introitus apertus ad occlusum regis palatium' by Eirenaeus Philaletha [cf. Ferguson op. cit. Vol. II, pp. 190-194], and it is noted that the German translation of this work published at Hamburg in 1705 has the title beginning 'Abyssus Alchymiae exploratus'.

The three volumes, which are paged continuously from 1 to 1497 are throughout written in the autograph of Charles Alston (1683-1760), Professor of Botany from 1720-1760. The heading is "Lectures on the Materia Medica. Begun in November 1720 and since several times revised, corrected and enlarg'd. By C. A." Wide margins have been left throughout, in which later additions have been inserted. The latest date is 1754.

Papers of Thomas Andrews including papers relating to his research which fell into four main fields;

(1) studies of acids and metals in electrolytic experiments; (Papers 6 to 11 and 32)

(2) the calorimetry of chemical reactions, in particular those between acids and bases, and between metals and halogens; (Papers 13 to 16, 18 to 22, 40 and the manuscripts printed as 52 and 53)

(3) the properties and constitution of ozone; (Papers 31, 33 to 35, 37 and 45)

(4) the condensation of gases to liquids at high pressures (Papers 36, 38, 41, 47, 49 and 50)

The eight volumes of manuscripts described as 'Notes of Experiments' at the Royal Society contain the laboratory records on which most of his work is based.

The contents are described as far as possible in Thomas's own words from the title pages of each Book. Where the title page is uninformative then suitable headings have been chosen from the body of the notes. These title pages may have been written much later than the experiments since in 1862 there is the phrase 'critical point' which he probably invented only for his Bakerian Lecture of 1869. Some experiments or paragraph numbers are displayed on the title page of each Book. Those that are not, but are listed only on the pages themselves, are shown at the right-hand end of each line. The numbering of the experiments is again erratic; for example 376 may be followed by 277.

The reading of the notes on the experiments on the liquefaction of gases in Volumes 7 and 8 is helped by comparing them with the analysis by C.G. Knott 'Andrews' measurements of the compression of carbon dioxide and of mixtures of carbon dioxide and nitrogen' (Proceedings of the Royal Society of Edinburgh, 30, 1-22, 290 [1909-1910])

These papers show Davy's first ideas for an electric telegraph from his early sketches in 1836 of a frictional electric telegraph to one worked by electromagentism which he developed 1836-1839. His first patent was lodged in 1837 in opposition to Cooke and Wheatstone's first patent. The papers indicate his efforts to find a purchaser for the patent rights and to establish a company to develop the telegraph. He made agreements with several business men but none of these arrangements bore any fruit. He also negotiated with the railway companies and demonstrated the telegraph for them. The papers record the efforts of his father, Thomas Davy, and several others, to continue Davy's negotiations with the railway companies and the arrangements which were made to re-exhibit a working model of the telegraph. The papers also relate to the sale of the patent to the Electric Telegraph Company in 1847. Fahie's memoir on Davy is included in the papers.
