Gentleman in the Name of the Roy^l Society^ to en- 
deavour by repeated Obfervations to confirm (bme of 
my late Difcoveries, and to fet them in To clear a Light, 
as to (lop the Mouths of the mod incredulous Gain- 
fayers. 
With regard to this, I beg leave to obferve to you, 
that I examine a great many different SubjetSls, of 
which I commit no account to Paper, bccaufe the Re- 
fult is the fame with what I have already deferibed; 
and that whenever 1 make any Difeovery, which I ap-

a Moufe lying befide them, in order to have as many 
Eye-W’itnefTes as poflTible, of their being of the fame 
fize in thefe two Animals, and 1 ufc the fame Method 
in fuch other of my Obfervations, as are likely to ap- 
pear incredible to other Perfons. 
In fpeaking formerly of the fmall FihrtlU^ that help 
to fufpend the TeQicles of a Ram, I forgot to men-
