_Pliny's Dentistry._--As your journal has become the repository of so many novel and interesting _facts_, I trust that the following data will be found acceptable to the readers of "N. & Q." Having had occasion, of late, to look over the works of Pliny, I was struck with the extent to which this ancient naturalist and philosopher has carried his researches on the above subject; as, in some editions, the Index of the article DENTES occupies several closely-printed columns. He recommends tooth-powder (_dentifricia_) of hartshorn, pumice-stone, burnt nitre, _Lapis Arabus_, the ashes of shells, as well as several ludicrous substances, in accordance with the mystic prejudices of the age. Amongst the remedies for fixing (_firmare_) teeth, he mentions _Inula_, _Acetum Scillinum_, _Radix Lapathi sativi_, vinegar; and loose teeth are to be fixed by _Philidonia_, _Veratrum nigrum_, and a variety of other remedies, amongst which some are most rational, and tend to prove that more attention was paid to the physiological (_hygeistic_) department relating to that portion of the human body than we have been hitherto aware of, as even the most recent works on Dentistry do not mention these facts. GEORGE HAYES. Conduit Street. _J. Farrington, R.A._--Having recently met with some views by J. Farrington, R.A., without a description of the locality, I shall be obliged by your insertion of a Query respecting information of what views were executed by this painter, with their localities, in or about the year 1789. As I am informed that those above referred to belong to this neighbourhood, and therefore would be invested with interest to me, I could ascertain their locality with precision. JOHN NURSE CHADWICK. King's Lynn. _Henry Crewkerne, of Exeter_, "Captain of Dragoons, descended from Crewkerne, of Crewkerne, in Devonshire," died at Carlow in Feb. 1664-5. Was he descended from Crewkerne of Chilhay, Dorset? His pedigree would be very acceptable. Y. S. M. _Dr. Johnson._--Johnson says somewhere that he never was in a tight place but once, and that was when he had a mad bull by the tail. Had he held on, he said he would have been dragged to death over a stubble field; while if had not held on, the bull would have gored him to death. Now my Query is, what did Dr. Johnson do, hold on or let go? G. M. B. _Latin "Dante."_--Is there not a literal Latin _prose_ translation of Dante, somewhat rhythmical? Has not Stillingfleet cited it in the _Origines_? If so, where is its _corpus_? And in what form, MS. or printed? Of metrical Latin versions there are several beside those of the Jesuit Carlo d'Aquino and Piazza. The Query is as to the prose? PHILIP ASKE.
