Whilst referring thus to our early lexicographers, allow me to allude to an anecdote respecting, Dr. Adam Lyttleton, who, when compiling his Latin Dictionary, announced the verb "concurro" to his amanuensis; the latter, imagining, from an affinity of sound, that the first two syllables gave the English meaning of the verb, said, "_Concur_, I suppose, sir." To which the Doctor peevishly replied, "_Concur_, condog." The scribe wrote down what he supposed his employer dictated, and the word "condog" was inserted, and stands as one interpretation of "concurro" in the first edition of the Dictionary; it is, of course, expunged from subsequent ones. I give this statement as I find it in print. I do not vouch for its correctness, not having the first edition of the Dictionary to refer to. Strange to say, however, "condog" was regarded as a synonym, or rather as an equivalent to "concur," long before the date of the first edition of Dr. Lyttleton's _Dictionary_. In Cockeram's _Dictionarie_, before referred to, sixth edition, 1639, I find the second alphabet, among the words which the author calls _vulgar_, the verb "to agree" defined "Concurre, cohere, _condog_, condiscend." Cockeram's _Dictionary_ was evidently a work of some authority in its day; it was dedicated to Sir Richard Boyle, and reached to, at least, a _sixth_ edition, which edition is announced in the title-page as "revised and enlarged," and therefore "condog" did not owe its place in it to the error of an amanuensis or transcriber. The book, although small, contains much curious matter, to which I may, perhaps, hereafter refer. In his "premonition to the reader," he says, "where thou meetest with a word marked thus +, know you that it is now out of use, and only used of some ancient writers." Among these words thus marked as obsolete in 1639, I find, on casually opening the book, the following, "abandon, abate, bardes, insanity." He also defines _Troy weight_ as "a pound weight of twelve ounces, wherewith _bread_, precious stones, gold and silver are weighed." Blount also (1670), and Cole (1685), say bread was sold by Troy weight; the latter adds medicines to the articles sold by that standard. Cowell, in his _Law Dictionary_ (1708), says, "Electuaries, and medicinal things, and _brede_, are to be weighed by Troy weight;" Bayley, in 1753, says, "Gold, silver, drugs," &c., are weighed by Troy weight, but does not enumerate bread. Can any of your readers inform me when bread was first directed to be sold by Troy weight, and when it ceased to be so? P. T. Stoke Newington. _Foreign Ambassadors_ (Vol. iv., p. 442.).--There is a list of French ambassadors, envoys, ministers, and other political agents at the court of England, in the _Annuaire_ of the Société de l'histoire de France for 1848, which is the twelfth volume of the series. The list commences in 1396, and is continued to 1830.
