III. A Letter from Mr. John Fergufon, Sur- 
geon , fo William Chifelden, Efq ; Surgeon 
to Chelfea College, F. R. S. &c. contain- 
ing an Account of the Extirpation of part 
of the Spleen of a Man . 
SIR , Strabane , 18. 1734-f. 
T HOUGH 1 have not the Honour to be known 
to you, I make bold to trouble you with the 
following Cafe, which lately happen'd in my Practice. 
I imagine it uncommon 5 for though you have taken 
the Spleen out of a Dog, without any remarkable In- 
convenience 5 yet it has never been attempted, that I 
know of, in a human Body. I affine you the Affair is 
literally true, and, if required, could have it attefted 
by feveral who were Eye-witndfes. As I believe you 
to be a Gentleman that is curious, and fond of any 
Difcovery that is new, I flatter myfelf you will not be 
offended with the Freedom I now take ; and that if 
you think this worth your Notice, you will be pleas'd 
to favour me with your Opinion of it, and whether 
you have known fuch a Cafe happen before. This 
will add to the Obligations I acknowledge myfelf 
under to you, for the Benefit I have already received 
from your Writings, which I greatly efteem, and am 
with the greateft Refpeft, Dear SIR, 
Tour moft obedient , 
humble Servant ,
