300 Nolices respecting New Booh. 



These experiments make it evident, that metaUic manganese 

 mJiy be united to cast iron by mixing it with a portion of char- 

 coal; and it is probable that a siniilar effect would take place ia 

 the puddling furnace. But as in these experiments with the 

 charcoal in mixture, the iron was not decarbonated or refined 

 enough, it cannot be porsitively inferred that the metallic man- 

 ganese would remain alloyed with the iron during the whole pro- 

 cess of refinement.

LX. On the Cosmogony of Moses. Bi/ 3. C. Frichard, Esq, 



To Mr. Tilloch. 



Sir, — X OUR correspondent F. E s has vainly flattered 



himself with the idea of having extorted from me a confession 

 v.hich I have not made. Far from allowing that I never sup- 

 posed him to have uttered the assertion 1 had imputed to him, 

 I pointed out the particular jiassage in which that proposition is 

 to be found, and where it is expressed in words the sense of 

 which can only be eluded by a mere quibble. 



F. E s having at length abandoned his attack on all the 



points which I have been anxious to defend, and contenting 

 himself with taking up a position on wholly different ground, 

 I am very willing to leave him in undisturbed possession of his 

 new quarters. 



I have the honour to be, sir. 



Your obedient servant, 

 Brjitol, Oct. 14, 1816. J. C. Prichard.
