Will you please forward the enclosed resumé of my Geneva results to Professor Plantamour. He finds for the seconds' pendulum at Geneva 0.993378m. This is not corrected for the flexure of the stand. As well as I can estimate, his stand is 5 times the stiffness of ours, and his pendulum must weigh about 10 kilograms. According to this, the correction of his value would +0.000119 m which would give for
Plantamour 0.993497 ‡ 2 m
Peirce 0.993493 ‡ 3
This only shows that we have no reason to suspect any want of accordance, which is not owing to known causes, between our results.
He has a smaller probable accidental error, because he began in November 1864 and continued the experiments at intervals till August 1871. My constant error, I will venture to say, is much smaller, not exceeding 1/100.000 part at most; while his must be ten times that.
He writes to ask my result and therefore I should like the enclosed sent to him.
Yours very truly and respectfully
C. S. Peirce

P. S. My results for the single days are absolutely independent of one another. But the European observers cover up the real discordancy of their results by first using them all to calculate a single value of a certain constant , where most of the discordancy goes, & then applying that to the several days which are thus bound to agree, pretty well.
