GERMAN SCIENTIFIC APPARATUS. 

 To THE Editor of Science : At the In- 

 ternational Exposition, Paris, 1900, the 

 jury having in charge Group III., Class 

 15, Instruments of Precision, Moneys and 

 Medals, were very much impressed with the 

 German exhibit. This exhibit was arranged 

 in a different way from that used by any 

 other nation. Germany made a joint ex- 

 hibition of mechanicians and opticians, and 

 arranged their apparatus in sections em- 

 bracing certain classes of instruments, and 

 thus departed from the usual custom of 

 arranging the exhibits under various firms. 

 This enabled the jury to see at once all in- 

 struments of the same kind grouped to- 

 gether in one case. 



The German Association printed com- 

 plete catalogues describing and illustrating 

 the apparatus exhibited, and these cata- 

 logues and descriptions were of very great 

 assistance to the jurors in making awards. 



The catalogues printed an introduction, 

 which gave in a very condensed form the 

 history of the work done in Germany in 

 improving the manufacture of instruments 

 of precision. I enclose an English transla- 

 tion of this introduction furnished by the 

 German Association, and suggest that it be 

 published in full in Science, inasmuch as 

 it shows by what methods the German 

 mechanicians have been able to produce 

 such splendid results. j. x. Eees
