The work of identifying- materials sent in by those not connected with 

 the Museum continues, as heretofore, to consume its full share of time. 

 The following list of special reports will serve to give some idea of the 

 extent of this practice. As stated previously, the department can not 

 make assays or analyses on such occasions, but whenever possible with- 

 out too great an outlay of time, the mineralogical nature of the mate- 

 rial has been ascertained and the applicant referred elsewhere for infor- 

 mation not obtainable here. These reports were made as follows:
