that day in faint lining a book of this size, would be nearly six 

 months, independent of the time required for cross ruling. The 

 worli reflects much credit upon Mr. Boynton, to whom the 

 Institute awarded its gold medal. 



Specimens of binding from Messrs. Bowne & Co., N. Y., and from 

 Messrs. Collins, Bowne & Co., were of an excellent character and 

 highly creditable. a. c. 



STEREOTYPE PLATES MADE FROM GUTTA PERCHA. 



Specimens of Stereotype Plates, made of gutta percha, were 

 a short time since presented at the rooms of the Institute, with 

 moulds taken from the type in the same material. These plates, 

 as far as the type was concerned, were as perfect as any metal 

 plates we have ever examined, and even more so. This new art 

 is progressing in the hands of ingenious men, and there is a rea- 

 sonable probability of its eventual success. The result will be 

 to lessen the cost of type iised, by lessening very materially the 

 quantity ; one set of moulds made from moveable type, will pro- 

 duce any number of sets of plates, and if applied to printing 

 newspapers, the saving in the expense of the moveable type will 

 be large. . a. c. 



GLOBES. 



Mr. Charles Copley, of Brooklyn, L. I., presented at the Fair, 

 specimens of Globes of his own manufacture, of very superior 

 quality, constructed from surveys up to the present time, embra- 

 cing all the new discoveries in all parts of the world. 



The celestial globe has been drawn upon the most scientific 

 principles, every star being laid down in its true position. Mr.
