1. Formulae. (Group C.). [Oxford: c.1878].
Bifolium (222 x 142 mm). Cyclostyled. Without wrappers, as issued. Rare cyclostyled pamphlet, with Dodgson's manuscript corrections in his characteristic purple ink. The formulas correspond to the topics in sections G and L of A Guide to the Mathematical Student in Reading, Reviewing, and Working Examples (1864). All of Dodgson's cyclostyle pamphlets were produced in unknown but small numbers.
2. Formulae. [Oxford]: 19 March 1878.
8vo. (218 x 140 mm). 1 p. Cyclostyled. Without wrappers, as issued. Another rare cyclostyled piece. Dodgson acquired his "electric pen" in 1877 and describes it in a letter dated 28 June 1877: it "seems to be quite the best thing yet invented for taking a number of copies of MSS, drawings or maps. The 'pen' consists of a needle, in a holder like a pencil: the needle is worked in and out with enormous rapidity by electricity and projects far enough to go through a thin sheet of paper... the paper thus prepared is placed in a frame with blank paper underneath, and an ink roller is passed [over it]... copies are easily worked off at a rate of 2 a minute." This work consists of 18 formulas corresponding to the topics in section L of the pamphlet A Guide to the Mathematical Student in Reading, Reviewing, and Working Examples.
3. Algebraical formulae and rules for the use of candidates for responsions. [Oxford: University Press, 1870.]
Bifolium (230 x 144mm). Printed on cream paper. Dodgson's diary mentions only Algebraical formulae for responsions (WMGC, 65) which he took to the University Press on 21 May 1868. It is possible that the present pamphlet is an expanded and improved version.
4. Arithmetic. I. [Oxford: University Press, c.1870].
Bifolium (227 x 144mm). Printed on cream paper. First edition, rare. The pamphlet consists of templates for 33 examination problems divided into 5 sections: integral numbers, vulgar fractions, decimal fractions, concrete numbers, and rule of three. The problems are stated in skeleton form, leaving blanks for the variables, so that new problems can be generated easily.
Four mathematical pamphlets offered together, preserved in a folding clamshell case. Each is quite rare; ABPC records only one other copy of each, the Falletta copies, selling at auction in the past thirty years (Christie's, November 30, 2005). $ 24,000.00
