it is figured in Plot's Nat. Hift. of Stafford- 
fhire. Tab. xi. Fig. 17. to one valve of this 
(hell I imagine, (or of Fig. 15, 16, of the fame 
plate, which is fomewhat of this kind, and alway^ 
found with its valves apart,) was fixed Fig. 13; 
Tab. XIII. of the fame work : my reafons are 
its being found at the fame place, viz. at Beref- 
ford in Staffordfhire; and the latter Fig. agree-* 
ing very near in fhape to Fig. 33. A. B. of 
this work. Plot having with deference to his 
readers defcribed a ftone, as the ftone of an aU 
mond, to which it did not in all refpeQs agree ; 
thus writes* of Fig. 13. of Tab. xiii. And I 
mull beg the fame licenfe for another of this kind, 
(flones formed like the fruits of trees) though 
one of the greatefl curiofities of this nature I 
ever met with, for notwithftanding it reprefents 
in general the true fhape of the bicapfular feed 
veflel of Digitalis fcrruginea, or of fome of the 
Verbafcums, having that patilous fiffure at the 
top, which the feed-veffel of that plant naturally 
has when it is ripe ; yet in the moft protuberent 
' part near the bottom, it is perforated with a 
fmall hole, round which there are feveral Jlrics 
or lineations bent (not equidiflant) but accord¬ 
ing .
