Notes of the action of aquafortis, and of salammoniac, on salt, and oil of tartar or potassium carbonate; and of crude tartar on the same, and of tartarum vitriolatum (potassium bisulphate) on same : with

p. 84, the remark that some fools call the result of the last reaction magisterium tartari vitriolati.

note, that salammoniac is less volatile than muriatic acid or ammonium carbonate, which seems to explain a quotation from D. von der Becke which follows.

note of calcination of lead with salt of antimony and salammoniac and of volatilization of arsenical tin when heated with corrosive sublimate and salammoniac.

pp. 85–92, extracts from Boyle.

p. 103, do. and of action of corrosive sublimate on antimony, silver, and mercury; of the heat produced by mixing oil of vitriol with water or spirit of wine; of the preparation of ether and oil of wine—not differing much from the account quoted on p. 64.

pp. 104, 105, note of warmth emitted on mixing water with spirit of antimony, and of sundry chemical reactions—the last on

saturation of spirit of antimony by different substances has blanks left for the quantities.

pp. 106, 107, other chemical experiments. Note of composition of fusible metal “ which in summer will melt in the sun,” with the (erroneous) remark that tinglas is more fusible than tin.

pp. 108–112, chemical experiments chiefly on preparations of antimony and scoria of regulus. Some of these (e.g. p. 111) are marked with an N in the margin.

p. 113, action of distilled liquor of antimony on salts of lead, iron and copper; action of heat on tartarised antimony.

p. 114, action of spar on distilled liquor of antimony, vinegar, and aquafortis, and of salt from clay of lead mines on do.; action of nitre on antimony.

pp. 115, 116, action of oil of vitriol on lead ore, and of an antimonial sublimate on several substances.

pp. 117–120, experiments with a substance to which the name ven. vol.” is given.

p. 121, note, that on May 10, 1681, and on the 14th and 15th he comprehended sundry alchemical names. This note has been scratched out, apparently in consequence of its having nothing to do with the subject of the other notes, but it is not certain that the foregoing experiments have not something to do with it.

p. 122, another note, that on May 18 he completed the solution of the alchemical symbol of the caduceus, followed by experiments on June 10 on sublimation of green and blue vitriol with salammoniac and the resulting sublimate with lead ore. Perhaps these experiments on sublimation were designed to test his interpretation of some alchemical symbols.

pp. 123 sqq. to 126, account of experiments in May and June, 1682; on sublimation of some salts with salammoniac, and some metals and alloys with the same, and with antimony.

pp. 127 to 130, June 26, 1682, and July 4, 1682, account of experiments on obtaining regulus from mixture of lead ores, antimony and bismuth ; and others similar.

p. 131, experiments on the action of various reguluses with spirit (? of salt).

pp. 132—4, other experiments on sublimation—the date, Tuesday, July 19, is given on p. 133; this must have been in 1683.

pp. 135 sqq., Feb. 29, 1683—4. An experiment in which he prepared the chlorides of mercury.

pp.
140
sqq.,

further experiments on " the net” which seems to contain iron and copper, and others of a similar kind. On p. 149 is the date, Friday, May 23.

pp. 262—4, blank. p. 265, recipe for ether, and its uses in medicine. p. 266, some recipes for medicines.

pp. 267, 8, continuation of experiments from p. 158. On this page is mentioned a liquor which dissolves the tinctures out of gold, silver, &c. and leaves only a white calx—but no directions for preparing it. Further experiments.

pp. 269–283, on regulus of antimony and alloys; similar in character to the former : rest of book blank, except 3

pages end, where is a list of prices of some chemicals in 1687 and again in 1693, and some notes of sublimation of vitriol with salammoniac.
