IV. A ^tjcripion of a new kind oj Walnut tree^ dij^ 
covered by Monfieur Reneaume, of the Koyal 
Academy of Sciences. 
T He Walnut-tree, which the Gree;^/ called fometimes 
X<*fw*6 Bct(r/MK», and fometimes ngjir/jt», in LaHh Nhx 
'jiiglans five Regia, is a Tree known to every Body, ''tis 
defcribed by very many Authors, who f neverthelefs) feem 
to have known but fix Species of it, tho I can reckon 
nine. They confounded (unkfs Vm deceiv'd) wth 
the common fort^ that which the Country people call l<loix 
Angleufes^ which one may call Nux Juglans pufamine du- 
rljjimo, which appears to me to be that which in Hermo- 
Id^is^ and in the Hiftoria Lugdunenfis i^ called Morati£ m^- 
racill^^ and which C^falpm calls Surd£. 
I don't fee that the fame Authors have diftinguifbed 
another Species,^ which might be called Nhx Juglans 
fruUii pr^coci^ becaufe they are (ooner ripe than the others, 
and eaten about the Feaft of St John en Cerneaux^ which 
has given them, amongft the Country people, the name 
of Noix Jodnnettes, As for that fpecies I am to treat 
upon, I can t find any Author that knew of it, and there- 
fore I (hall call it Nhx Jnglans^ folio eleganter dijfe&o, 
or Acanthi' folia. 
I (hall not fpeakof the ufes of the Walnut-tree, nor of 
its Fruit, which it yields in great plenty. I will 
only fay, that the Oil which is preffed out of it, in 
certain Provinces is ufed inftead of Butter and Oil-Olive, 
In Berry, where they have very good Wool, and where 
they Trade very much in Cattle, they have yet but very 
little Butter 5 and that little which they have is worth 
nothing, and is very dear 5 fo that they ufe Nut-Oil in 
dreffing
