I. Tart of a Letter from the Tgverend Mr. Wafle, 
( T^eftor of Aynho in Northarnptonfihire, to 
Dr. Mead, concerning the difference in the Height 
of a Human Tody , between Morning and Night . 
I Have obferv’d feveral Soldiers difcharged for being 
a little under the Standard, and having experienced 
the difference of a Man’s Height in the Morning and 
at Night, I mentioned it to an Officer, and thereby 
kept Tome Perfons from being turn’d out of the Ser- 
vice. Since , that Time I have meafured Sir H. A .... , 
Mr. C , and a great many fedentary People, 
and Day-Labourers, of all Ages and Shapes, and find 
that Difference to be near an Inch. I try’d my felf, 
w henfitting, and found it in like manner ; particu- 
larly, Augujl z i . 17x3. Weather warm, no Wind, at 
Eleven in the Morning I fat down, and fixed an Iron 
Pin fo as to touch it, and that but barely. After that, 
I fatigued my felf for half an Hour with a Garden- 
Roller, and the Confequence was, that at 12 Ho. 30 
Min. I could not reach theNail fitting, by about 5Tenths 
of an Inch, or the Breadth of one of the Rods of 
Hunt's Sliding-Rule. At 2 the fame Day I wanted 
near fix Tenths of an Inch. On the 21ft, at 6 Ho. 30 
Min. in the Morning, I touched the Nail fully ; and af- 
ter the above-mentioned Exercife for only a Quarter 
of an Hour, at 7 Ho. 14 Min. I fell fhort almofl as 
much as before. On the 27th, having fat up late with 
fome Friends, I was faint, and felt my felf heavy upon 
the Ground, and without any Spring, and at 9 that 
Morning I did not reach the Nail, though I had us’d no 
Vol. XXXIII. P Exercife.
