M^r Newton Our former aquentance Imboldeneth me to troble you with these few lines: which is to Intreat your {fawor}{faivor} If that an oppertunity will serve: To peruse over this Small Table of the Suns Azimuth for the Latitude of ${52}^{\mathrm{degrs}}{00}^{\min }$ which is for Every Hour of the day & night: being from the Equinoctiall to 24 degrees of declination being Eather North or South for Every 4^th degree of declination: the Azimuth Being from the East or west Eather North wards Or South wards{.} And Likwise this Table of the North Stars Azimuth which is shewed from the North for Every hour Eather above or belowe the pole which is for Every 10^th degree of Latitude from the Equinoctiall to ${60}^{\mathrm{degs}}$ of Latitude: which I would intreate your favour to Examine & give me notice thereof whether the proportions hold good or not: vizd whether these Tables Shew the Sun or North Stars True Azimuth as I have heare shewed by these tables or not. As for this way of Azimuth it is by a way of my owne contriveing by such a way as I never see nor heard of before which maketh me more desirus to have your oppinion thereof: As for this way of callculation I do not at all conserne my selfe with the Altitude {illeg} {o}nley with the Declination: so that the Azimuth for Every Hour is found as soone or sooner then the Hourly Altitude which is by such a duble way of workeing for the Hour of l0 & 2 for North Declination & 10 & 2 for South Declination & the Hour of both sixes is wrought by the product of one Multiplication which is to be Added to or Subtracted from a Nother Summ & then takeing $\frac{1}{2}$ thereof sheweth 6 Hours Azimuth: So that the whole 24 hours Azimuth is wrought per the produce of five multiplications by being Added or substracted from An orther given summ which is Allwayes a certane Summ for that hour & Latitude to any declination{.} I have heare in some places not onely sett downe the degrees & minutes but have shewed by pricks to a quarter of a minute in some places{.} But if I would have bene presise in this Calculation per this way of callculating of the North Stars Azimuth I could have sett downe not onley the minute But likewise that to one thousand part of a minute & that by the same Radius by which this was Calculated{.} But this I Suppose is neare enough if that the proportions hold good which I would desire you to Examine & give me notice thereof which if it be within 14 dayes After the {dait} of this I may Receive it If that you direct your Letter to M^r William Kings Junior Silkeweaver In three horshoo alley in Old Streete in London I shall Receve it: Haveing no moore at present But my dutye to my {unckle} & my service to your selfe hopeing that you ar both well as praised be god I am I Remane

A your Command to serve you Arthur Storer

London Sept 4^th: 1678

I sent you a former table by {unckle} Babington of the North Stars Hourly Altitude & Azimuth
But in that {thereof} table of the Suns Azimuth was Omitted which I hope you have Receved before this{.}
