HENRY MARSHALL TO LORD BURGHLEY.
[MS. Lansd. 101, Art. 16. Orig.]

Right Honorable,_Forasmuch as I have of late devised two rare inventions, the which may be profitable to my contrye, and damageable to the enemyes thereof; I thought it my dutie (having found your honour alwayes my especiall good lord) to offer the discoverie of the same to your lordship before anye other. The which if your honour shall thinke worthie, maye be then imparted unto Her Majestie. The first is an engine, whereby the walle of anye towne or castle maye be defended from the force of anye canon: and the other is an engyne, which shall breake the araye of anye battell being readie to joyne: the which engynes are easilie made, and yett neither verie chargeable nor paymefull to transporte. And because I understand your honour to be delighted with such rare inventions, I thought it good to make modelles of the same, whereby your lordship may the easelier conceave my intention, and the better judge of the benefitt and sequell pretended. Thus fearing to be troublesome to your honour, and craving pardon for this my rashe boldnes, I wish your honour good health and long life to God’s pleaSure.

Your honour’s most humble in all duetifulnes,
HENRY MARSHALL.

Lord Burghley, Lord High Treasurer of England, London, the 1st of June, 1595.

WILLIAM LOWER TO THOMAS HARRIOT.

[MS. Addit. 6789. Orig.]
Ira 'venti, March 4th, 1611.

Sir, I never loved huntinge till you furnished mee with dogs, I will henceforward prove another Nemrode; indeed I sought both arkes and tangents in the tables by proportion onlie; so, in a worde, you have made me see my faulte; in two or three more you have taughte me to amende it; onlie your curre dog Petiscus will not come into my sighte; but after a weekes vaine anger and points in seekinge for him, I found at last it was not the poore curres faulte, but Mr. Bills, that, sendinge me the second edition of the Origonometria, sente me onlie the tables; so as turninge the pages 75, 76, 78, 79, of the first edition (which is all I have) I found no such thinge as you sited, nor no such examples as you added. This is not the first time that Bill hath sent me imperfect copies; I pray let him understand so much. So you see I am defeated of the curre dog, savinge what I pick out of

your letter, which indeed is not enough to give me satisfaction. Let Kitt, when he goes next to London, speeke to Bill, or att the Blackfriers, for a perfect copie of Petiscus; my brother the captaine will send it to me speedilie. The touch that you give of your doctrine of differences or triangular nombers, . . . . me of them, wherin to understand somethinge, I will one day bee a begger unto you. Your dog, that hunts by the sines onlie, and I am growen familiar, and he is an excellent dog; but your she bitch hath no fellow for . . . . , onlie she is slow; I had not lost hir, but knew hir goodnesse wel enough: the reason why I did nott use her in the former workes, was because, beinge in way of calculation by the tables onlie in that practise, I endevored to cleare that way of all rubbs; also because I conceaved it to be the shortest, I hastned (so greedie was my desire) to see the issue of my worke; so that by the assistance of thes dogs of yours I grow so confident as to undertake to pursue in chace anie game: but then onlie I shal be sure that nothinge doe escape me, when you shall please to imparte unto me a betch of your triangular kinde. I need not bee so curious to send you my doubts in individuo, for howsoever you satisfie me in private as you have done now, nevertheless, because you require it, I have sente them in two supplements, the one unto my letters that you have alreadie, the other unto thes, which, unlesse you had remembered me of, I should have omitted againe. My worke is crowned now you allow of it, and indeed ther wanted in mee nether will nor industrie to accomplish it, nor in you will nor skill to instruct me in the sacred wayes of arte; be you therfore ever of me unconquerablie respected, or be I not att all. You have recomforted mee much to intimate that anie greate difference in my workes will discover a farther misterie; for I was almost dismaied to find thes second observations give an Aphelie different for the former 3 or 4 degrees. Of this later worke I send you all the numbers given and found, and had also of manie more by this time, if the impossible issue of this last worke had not stayed my proceedinge till I receaved your censure of it. As you direct me I will proceede to doe them all, for I am growen verie experte in this calculation. I did not mistake that a 3 in the diagramme I sent you was double the eccentricitie, and therfore, before the recepte of your letter, in this second worke I had placed 3 att the center, and o att the centrorde, not onlie that a 3 mighte still remaine with Kepler the single eccentricitie, but to make it also corresponde with your vice royall probleme beare with

this imitation. Concerninge the Joveall starres I writte nothinge of them last, because I had nothinge to writte; for indeede, although both I and the yonge philosopher att Hanbesbrooke have often and in verie cleare nights (when Presepe was most plaine to bee seene without the cylinder); when wee, I say, have often diligentlie observed Jupiter, wee could never see anie thinge; I impute it to the dullnesse of my lighte, for onlie with your greate glasse I could se them in London. That you have made so manie exellent observations of them I am most glad of, for you have gotten the starte of all in limitinge ther periods. Ther periods are verie merveilous, especiallie that of Jori proarimus, whos scituation also is no lesse merveilous, beinge not one diameter of Jupiter of from him. Of thes thinges and thos other mirabilia quae indies juvenis, I longe to bee with you to discourse of them. My wife is well. Now you know all my comfortes. I have lost my second boy also, and wel neere eighty catle of the murraine, and the die still ; now you know all my discomfortes and losses. Farewell, and lett not the hugenesse of this missive discourage you from reedinge of it; doe it at leisure and by peeces accordinge to your best opportunities, and sometimes use the power you have in me, which is to dispose of mee accordinge to the utmost of

all or anie of my abilities. Your faithfull frind, WILLIAM Lower.

By the helpe of your dogs, I will revew all thos workes of anie that exhibite the distance in the ellipses, equal or neerest to the same distance found before (for the workes uppon the former positions of 3 in the eccentricke, which were onlie to find out this, I thinke you care not for); and when I have perfected them, I will send them unto you, with all the numbers given and found, whether the quesite consent or no, since you so require it.
