880 TRANSACTIONS OF THE AMERICAN INSTITUTE. 



all the substances found in the other Saratoga Avaters and in the 

 German Seltzer — to make it a most valuable remedial agent. 



Its physiological effects have been already tested by numerous 

 persons who have used it daring the past year, and it has been 

 proved to possess all the valual)le properties which have so justly 

 given the Saratoga waters their world-wide reputation. As a 

 cathartic, diuretic, alterative, tonic, &c., its action is found to be 

 most satisfactory. When properly bottled, the water retains all 

 its agreeable properties indefinitely, and remains perfectly clear 

 and free from sediment. 



The following new inventions were exhibited and explained : 



New Printing Machine. 

 Mr. Buell exhibited a new printing machine, intended chiefly to 

 facilitate copjang, though it may, however, be used to print circu- 

 lars, and almost everything used in offices. The type are all 

 arranged in a circle, all meeting in a common centre. They are 

 inked by a ribbon, as in the ordinary die stamp, and are acted 

 upon by a set of keys such as are used in pianos. The operator 

 strikes a key and thereby raises a letter, which prints a character 

 on the paper. The rapidity and accuracy with which this may be 

 done depends solely on the expertness of those using the machine. 

 A 2;reat advantag-e is ""ained bv arranofino; in the centre of the key 

 board those letters and combinations of letters Avhich most fre- 

 quently occur. Specimens of the work were handed round, and 

 were much admired by the audience. It was doubted if the 

 machine could print faster than a good penman would write. 



Machine foe Making Stereotypes. 

 Mr. Boyd Elliot described a machine somewhat similar, intended 

 to form a matrix for stereotypes, by making impressions in thick 

 soft paper of the letters, words and characters. The work can be 

 done three times as fast as printers can set type. By this process 

 a vast saving of labor can be efll'cted in composing rooms of all 

 printing establishments. Music can be printed perfect and with 

 great rapidity. After the impressions are made on the sheets of 

 thick blotting paper specially prepared, stereotype plates arc then 

 cast from the mould or matrix.
