STATEMENT OF REGISTRATION FROM VOLUME I OF THE REGISTERS 



TO JUNE 30, 1885. 



The mode of registration hitherto, owing to the practice of setting 

 aside sets of numbers for specialists working on Museum material, has 

 been very irregular. To avoid the trouble hitherto encountered when- 

 ever any question of registration has been raised, I have had a com- 

 plete collation of the books made, those entries which had been left 

 blank by inadvertence being assigned to the year most probable from 

 other considerations. This shows that to date 42,440 entries had been 

 made in the registers, a number equivalent, at the ratio of two and a 

 half specimens to an entry, a fair average, to 100,100 specimens regis- 

 tered and labeled. In 187G Dr. Lewis revised the whole of the Ameri- 

 can land and fresh-water shells, for which he used 4,050 entries, of 

 which about 3,500 were second entries of the same specimens, a plan 

 adopted to save time and trouble, but somewhat objectionable on other 

 grounds. Deducting these, leaves 07,350 specimens, to which may be 

 added 12,000 entries of about 30,000 specimens made since June 30, 1885. 

 There being at least an equal number of unregistered specimens, and 

 probably more, this would bring the census of the collection as a whole 

 up to 260,000 specimens as a minimum.
