 philosophical and chemical apparatus, and optical and 



mathematical instruments. The business in Baltimore will 

 be continued under the care of his brother, who will be kept sup-

 goods in Baltimore, which may be a convenience to Southern

the manufacture of Apparatus, will enable him to meet the orders 

 of his friends, with increased satisfaction and greater promptness. 

 In addition to articles of his own make, his personal acquaintance 

 with the principle makers of Europe, gives every facility for the 

 importation of instruments; and at the same time, secures an 

 early knowledge of all improvements made there : this assistance, 

 joined to a constant attention to the progress of experimental sci- 

 ence, puts it in his power, he trusts, to supply every description 

 of apparatus, for demonstration or research, on very favorable 

 terms. 



Special attention will be, still, given to the manufacture of the 

 more accurate class of instruments required for refined observa- 

 tions — particularly in Meteorology — both for Stationary Stand- 



ards and portable instruments.
