Father Johannes Baptifta Villalpandus, ajefuit 
of Cor dou a in Spain , in his Apparatus Ur bis et 
Tempii I-liercfolymitani , printed in folio at Rome 
in 1604, exhibited a table of the proportional weights 
of the (even metals and fome other fubftances, from 
his own experiments, made with great care as he 
tells us, by the means of fix equal folid cubes of the 
fixed metals, and a hollow cubical vefiel 8 times as 
large, for the comparing Mercury, Honey, Water, 
and Oil with the fame. His numbers, which are 
inferted under his name in the following tables, 
were alfo again publifhed afterwards by Job. Hem. 
Aljledhts in his Encyclopaedia univerfa, printed in 
2 vols. in folio at Her bom 1630, and by Henry 
Van Etten , in his Mathematical recreations , from 
whence they have been often tranferibed into other 
books. Villalpandus's book, which is only the third 
volume of a work begun to be publifhed feveral 
years before, was itfelf printed fo foon after Ghetal- 
dus’s, that it is probable he either never faw that 
author, or not at leaft till after his own experiments 
were made. 
Mr. Edmund Gunter , in his Hefcription and 
Ufe of the Settlor, printed after his death by Mr. 
Samuel Fofler in 1626, having occafion to make 
mention of the fpecific weights of the feveral fixed 
metals, quoted Ghetaldus , and made ufe of his pro- 
portions, and fo did alfo Mr. William Oughtred , 
in his Circles of Proportion, firft publilhed in quarto 
1 633, with this only difference, as to the form, 
that he changed Ghetaldus’ s unit into 210, whereby 
he expreffed all his relations in whole numbers. It 
is likewife probable that©. Henrion took from the
