From L. J. Jones 1 November [1881]1
102 Mount St. | London, W.
Nov 1st,
Dear Sir.
On page 165 of your recent work on Vegetable Mould the number of pounds ejected per square yard is given as 83.87. This is an obvious misprint, & I at first thought that the decimal point had slipped into the wrong place. The total however of 18.12 tons per acre gives, it seems to me 8.353 lbs per sq. yd. instead of 8.387.2
I am unable to arrive at quite the same total from the data given on the preceding page, as
1lb. 13oz for of days
= 7.477 lbs. per sq. yd.3
The deep interest with which I have read your book and the importance of accuracy in details of which it is so signal a proof must be my excuse for troubling you on a point which has probably attracted your attention long before this.
I remain | your obedt. servant | Lawrence J Jones.
