110 Account of a nexv Pummice Press, 



intended only for a model ; not adverting to the space 

 left for a much larger crib ; nor instantly perceiving that 

 both levers, acting xvliolly -within the machine^ press with 

 equal force, both upwards and do^vnwards ; but no one 

 who has examined it, has failed to express his opinion 

 of its promising fair to become really useful; and if it 

 shall prove to be so, it will aflbid me ample satisfaction 

 for my trouble. 



Be this as it may, I am convinced that the best chance 

 for becoming so, will be derived from your care and 

 attention, to which it is committed with the greater 

 pleasure, as I confide that you will allow me the credit 

 of a respectful attention. 



I am your most obedient, 



humble servant, 



T. Matlack. 



Hon". Richard Peters Esq^. 



President^ Agric. Society^ Philad*
