Your correspondent J. M. (Vol. iii., p. 340.) asks what has been accomplished at Herculaneum in the late investigations. Alas! a few thin folios at my side contain all that the most unwearied exertion, and ever-renewed patience, have been able to bring to light. A few tracts of Epicuros, Philodemos, Colotos, Polystratos, Demetrios, and Carneiscos, are the results of the labours at the "City of the Dead." It is much to be desired that the investigations should be recommenced when the troubled condition of the kingdom of Naples will admit of it. I refer J. M. to M. Morgenstern's excellent article on the subject in the _Classical Journal_, vol. vii. p. 272. _sqq._, and the _Herculanensium Voluminum_, Oxonii, 1824-1825 (Press-mark, 604 f 15, British Museum), and the splendid folios of Naples, 1793-1844 (Press-mark, 813 i 2.). KENNETH R. H. MACKENZIE. MS. NOTE IN A COPY OF LIBER SENTENTIARUM. (Vol. iv., p. 188.) _Peter Lombard, Gratian, and Comestor_ (Vol. iv., p. 188.).--Your correspondent W. S. W. alludes to the above-mentioned worthies. I extract from Bishop Jeremy Taylor a passage or two in support of the story of their brotherhood: "It is reported of the mother of Peter Lombard, Gratian, and Comestor, that she having had three sons begotten in unhallowed embraces, upon her death-bed did omit the recitation of those crimes to her confessor; adding this for apology, that her three sons proved persons so eminent in the church, that their excellency was abundant recompense for her demerit; and therefore she could not grieve, because God had glorified Himself so much by three instruments so excellent: and that although her _sin_ had _abounded_, yet God's grace did super_abound_. Her confessor replied, '_At dole saltem, quod dolere non possis_ (Grieve that thou canst not grieve).'"--Sermon "On the Invalidity of a late or death-bed Repentance." _Sermons_, p. 234. Lond. 1678. And again: "To repent because we cannot repent, and to grieve because we cannot grieve, was a device invented to serve the turn of the mother of Peter Gratian."--_Holy Dying_, "Practice of Repentance in Sickness," Sect. vi. Rule 5. Lond. 1808. RT. Warmington. W. S. W. (Vol. iv., p. 188.) invites attention to a manuscript note in his valuable copy of Peter Lombard's _Sentences_ (ed. Vien. 1477), by which Lombard, Gratian, and Comestor are described as "_fratres uterini_." Antoninus, Archbishop of Florence, wrote about A.D. 1445. His account, therefore, of this clearly fabulous story must be somewhat earlier, as it is (at least in one particular) more curiously circumstantial. His words are (_Chronic. Op._, cap. vi. p. 65., ed. Lugd. 1586):
