It is proper to say, in explanation of the fact that the total number 

 of specimens does not balance with the sum of the accessions for the 

 year and the total of the previous year's report, that some of the acces- 

 sions prove to be triplicates and are absorbed in the duplicate list, that 

 a small i^ercentage of specimens is every year rejected as worthless, 

 either originally or by unavoidable deterioration, and that the illustra- 

 tions are not entered in the catalogue.
