NOTES AND QUERIES. [ii s. VH. MAR. s, 1913.
Nevertheless, this same list gives Lawson's
" Synopsis of all the Data for the Construc-
tion of Triangles, 4to, 2s. 6of.," and as this
pamphlet contains only 24 pages, a forty-
page pamphlet might well cost " 3s. 6d."
In The Mathematician for July, 1849 (iii. 313), T. S. Davies (a most careful and accurate writer) remarks: "....it is less to be regretted that Lawson did not com- plete his translation than it otherwise might have been."
But did Lawson publish anything beyond the fragment described above ?
On p. 122 of his ' Elementary Treatise on Cross -Ratio Geometry ' the Rev. J. J. Milne has the following foot-note :
" On the outside cover of an Appendix (1847) to Potts' larger edition of Euclid there was a notice that it was proposed to publish by sub- scription a translation of Simson's ' Restoration of the Porisms.' The translation was to be pre- ceded by a discussion of their peculiar character, together with a full development of the algebraical method of investigating them."
" If a number of subscribers had been obtained sufficient to defray expenses it was intended to print the ^ork at the University Press in octavo, and to issue it at a price not exceeding ten shillings."
In The Mathematician for July, 1849 (iii. 312), T. S. Davies writes :
" I am not without the hope that Mr. Potts' translation of the [Porisms]. .. .with valuable explanatory notes and illustrations, will not be long delayed."
And in The Mathematician for September, 1850 (iii., Supplementary number, p. 42), occurs this sentence from the pen of T. S. Davies :
" In the notes on Mr. Potts' translation of Simson's Porisms, I shall give a sufficiently full account of Mr. Noble's views . . . ."
Was Potts's translation ever published ?

HERBERT SPENCER'S PATENT. It will be remembered that in his ' Autobiography ' Herbert Spencer relates that he invented and patented a kind of paper-clip which brought him in, if I remember rightly, about 70Z. It was soon superseded by a novelty nowise superior to it in the same kind. Are any examples of Spencer's invention still to be met with ? Does any corre- spondent happen to possess one ?
HYLLARA.
CRECY. Can any one kindly inform me where I may find a list of those who fought at Crecy (1346), especially of the Welsh knights present, with details of biography, &c. ? GAUCHO.
MLLE. FENNYVESCI. Where could I find
more particulars about this lady ? She is
mentioned in Lady Lyttelton's letter dated
from Windsor Castle 24 Aug., 1839. She
drove out with the Royal party, and sat
with Lady Charlotte Dundas and Lady
Lyttelton in the same carriage.

DATE OF 'BOOK OF HOURS.'
(11 S. vii. 108.)
THIS appears, without doubt, to be one of the printed Horae issued by Antoine Verard, the Paris publisher, and the copy which your correspondent has is No. 241 (p. 112) in Mr. Macfarlane's monograph on Verard, and No. 143 in Brunet. There are vellum copies in the Bibliotheque Nationale, the Fitz- william Museum (Cambridge), and in the Bodleian. There should be eight leaves without signatures, followed by 114 un- numbered leaves. This Horae, believed to be for the use of Chartres, was completed on 21 July, 1508. The device of the pub- lisher, Verard, is composed of three initials A. V. R. Your correspondent has not noticed that the V is formed by the space between the A and the R. If he will look again, he will see the V quite clearly. Ve- rard's devices have been illustrated in Silvestre's 36 and
ii. 26. Before 1489 the device used
by Verard was rough, and had variations ;
see Picot's ' Catalogue of the Library of
Baron James de Rothschild,' under the
entry of ' Les Lunettes des Princes.' For
the sets of initial letters used by Verard,
see Macfarlane's monograph, p. xxv; and
for the origin, &c,, of Verard's illustrations
to his Horae, see the same work, p. xxix and
Appendix. For the types he used, consult
Proctor, ' Early Printed Books ' (pp. 603-4).
Verard had a doubtful reputation, and the
mutilation or deletion of the colophons to
his books (as in your correspondent's copy)
is not unusual. The reasons are not quite
clear, but they appear to be connected with
a desire to get rid of the date. Verard's
business of publisher was carried on at
various addresses, and when the book which
is the subject of this query was issued his
house of business was close to Notre Dame,
where he had moved in September, 1503.
