REPORT OF CURATOR OF MINERALOGY. 



• Cincinnati, April 3, 1885. 

 To the President and Members of the Cincinnati Society of Natural 

 History : 



The Society has not received any large accessions to its depart- 

 ment of Mineralogy during the past year. Our cases are full and 

 we can not arrange any more specimens until we have more space 

 provided for their reception. In my last report I made a sugges- 

 tion in regard to making a special collection of rocks, minerals and 

 specimens illustrative of petrology. The Board did not see fit to 

 act upon the suggestion, or at least I never heard from it in refer- 

 ence to the matter. Such special collections are very valuable 

 additions to our Society, for they can be made an object-lesson 

 study for students. When they come to our rooms now they are 

 lost in the multitude of forms, and go away with a necessarily vague 

 and confused idea of any department. I proposed, in my last re- 

 port, and do v so again, at the risk of seeming importunate, to have 

 a collection of three cases. 



First, " Rocks, " which will be so labeled, and have attached to 

 it a manual for reference, so it will illustrate very fully, for any 

 student, the whole subject of lithology. 



Second. Another case to contain minerals, typical forms — both 

 crystalline and massive — which will illustrate that subject very 

 completely. It will have also an explanatory manual attached. 



Third. A case illustrating " Petrology, " or a series of rocks es- 

 pecially selected to show ripple-marks, mud-cracks, raindrops, fault- 

 ing, folding, etc. These cases will contain about 350 specimens, 

 all carefully labeled and located, this last being a very important 

 matter to any student of this branch of science. They will cost 

 about $50 only — a very low price for such a valuable addition to 

 our collection. 



The following is the list of exchanges and donations received dur- 

 ing the past year : 



Sixteen specimens by exchange. 



Twenty-five specimens, miscellaneous donations. 



Also special donations by Col. Abert, Mrs. Eli Kinney and E.
