[1352] Digby MS. 55 contains a treatise on grammar falsely attributed to Bacon; inc. ‘Scientia est ordinatio depicta in anima.’ See Opera Ined. p. lxv.
[1353] Royal MS. 7 F vii (see above) speaks of eight sciences, i.e. including what Bacon calls ‘scientia de communibus naturalibus.’
[1354] See the works under the heading, Alchemy: cf. ‘Excerpta ex libro sex scientiarum’ in Sanioris medicinae, &c. (Frankfurt, 1603), p. 7: ‘Quarta vero scientia non modicam habet utilitatem ... et est Alchymia speculativa.’
[1355] The Breve Breviarium includes a treatise De vegetabilibus et sensibilibus, and another De medicinis et curis corporum; edition of 1603, pp. 228 and 156; MS. Bodl. E Musaeo 155, pp. 549 and 553.
[1356] Printed in Opera Ined. p. 359 seq.
[1357] The special treatise on alchemy in this work does not seem to be extant. Cap. vii of the Communia Naturalium begins, ‘De generacione. Habito ergo de principiis naturalibus generacionis.’
[1358] Sloane MS. 3744, p. 71 (sec. xv) contains Errores secundum Bacon. Inc. ‘Scito enim quod omne corpus aut est elementum aut ex elementis compositum.’ According to Charles (p. 71) this is the De Erroribus medicorum.
[1359] Charles, R. Bacon, p. 76. It is often, perhaps rightly, attributed to John de Rupescissa.
[1360] Brewer reads, ‘Explicit liber tertius De Consideratione quartae Sententiae S. Magistri per Rogerum Bacon,’ &c. His whole account of this MS. is not very trustworthy; Op. Ined. p. xxxix.
[1361] Cf. MSS. Sloane 284 (sec. xiv), 477 (A. D. 1309), and 2411; Digby 150 (sec. xiii), f. 106, ‘Extracciones a Thezauro pauperum, libro scil. preceptorum medicinalium.’
