[A very slight roughening of 

 the surface, but no granu- 

 lation and but slightly at- 

 tacked on the edges or 



I arrises. 



^Surfaces very slightly rough- 

 / ened, but no granulation. 



^Surfaces very slightly rough- 

 / ened, a slight yellowing. 



\Surfaces roughened, but no 

 / granulation. 



Surfaces distinctly roughened 

 and granulated, small par- 

 ticles loosened and falling 

 away when handled or 

 brushed; arrises rough- 

 ened. 



Surfaces distinctly roughened 

 and granulated, small par- 

 ticles loosened and break- 

 ing away when handled or 

 brushed; arrises strongly 

 attacked. 



Surfaces roughened by the 

 corrosion of the colorless 

 granules leaving the pmk 

 tinted standing in relief. 

 No granulation or mechan- 

 ical loosening of particles. 



>No perceptible change. 



(Surfaces distinctly roughened 

 by corrosion along planes 

 of cleavage and color 

 changed to a decided buff. 



|No perceptible change. 



No perceptible change. 



Surfaces much roughened 

 and pitted owing to solu- 

 tion of the oolites leaving 

 the fossil fragments and 

 crystalline material of the 

 interstices in relief; arrises 

 strongly attacked. 



The same, only that the stone 

 is more distinctly oolitic 

 and the surface becomes 

 covered with circular and 

 oval pits.
