REPORT ON EXCHANGES. 



It has been suggested that the intervals between the receipt, by the 

 Smithsonian Institution, of packages and their delivery to the consignee 

 miglit perliai)s be lessened by some improved method of transmission. 

 If there is ground for complaint of tardiness in the delivery, such charge 

 can certainly not be made against the exchange office, in which but 

 very small delays occur between the receipt of exchange packages and 

 their transmission. 



In order to illustrate this assertion I now beg to submit the follow- 

 ing tables of transmissions to France, Germany, Great Britain, and 

 Italy. In each case twenty invoices have been selected at random, ex- 

 tending over a period of almost three years, and their history has been 

 traced from the ledger accounts as follows : 



FRANCE. 



GERMANY.
