![cease with the motion of the Chord; but I chose to ex- press my self as I have done that You might the more clearly understand me. In altering the Proposition I altered the 4th line of Page 366 by putting PI, Pm, Pn instead of Pn, Pm, PI; & in the 2d line of Page 367 in- stead of [ob brevitatem pulsuum] I have put it [ob angus- tos limites vibrationum] for it would be truer & more to the purpose to say ob magnam pulsuum distantia\m\ than to say ob brevitatem pulsuum. In Your Example taken from Mr Sauveur the latitude of the Pulse is about 10 foot, when perhaps ye space of Vibration is not above ye 10th of an Inch at ye utmost. If You consent to my Alteration of the Proposition the Figure must be altered. I propose to have it cut like ye Figure I sent You, which does better express the disproportion of ye breadths of ye Pulses & Vibrations than the former Figure. I am Sr. Yr &c. LETTER XXXI. COTES TO NEWTON. Sr Sept. 4th 1711 I received a Letter from you about a Month ago, & sent You an Answer to it the next day by ye Carrier, in which I gave You my reasons why I was not yet satisfied as to ye Inconsistency in the 48th Proposition & its Corol- lary which I formerly mention’d to You. I have not heard from You since y* time, & therefore I fear that either my Letter or Your Answer to it has miscarried. I shall be glad to know Your resolutions concerning this 48th Propo- sition assoon as You have leasure that the Press may go on. There were some things relating to the 3d Book in my former Letter, I hope You will not forget to let me know Your mind concerning them also. I am Sr Yr. &c.](https://iiif.wellcomecollection.org/image/b28738317_0162.jp2/full/800%2C/0/default.jpg)
