fire; 3, White porcelain biscuit, of a smooth, wax-like 

 appearance, of similar properties with the preceding ; 4, Jasper, 

 a white porcelain of exquisite beauty, possessing the general 

 properties of basalts, together with the singular one of receiving 

 through its whole substance, from the admixture of metallic 

 calces, the same colours which those calces give to glass or 

 enamels in fusion — a property possessed by no porcelain of 

 ancient or modern composition ; 5, Bamboo, or cane-coloured 

 biscuit porcelain, of the same nature as the white porcelain 

 biscuit ; and 6, A porcelain biscuit remarkable for great hard- 

 ness, little inferior to that of agate — a property which, together 

 with its resistance to the strongest acids, and its impenetrability 

 to every known liquid, renders it well adapted for the formation 

 of mortars, and many different kinds of chemical vessels. The 

 above six distinct species of ware, together with the " queen's 

 ware" first noticed, have increased by the industry and in- 

 genuity of different manufacturers, and particularly by Wedg- 

 wood himself and his son, into an almost endless variety of 

 forms for ornaments and use. 



Josiah Wedgwood closed a life of useful labour on 3rd 

 January, 1795, in the sixty-fourth year of his age. Having 

 acquired a large fortune, his purse was always open to the calls 

 of charity, and to the support of every institution for the public 

 good. To the poor he was a benefactor in the most enlarged 

 sense of the word, and by the learned he was highly respected 

 for his original genius and persevering industry in plans of the 

 greatest national importance.
