 We have better things to do than to play with methods of stain-

 reached its highest perfection in America, where technical talent 

 is so remarkably developed. Although such photographs are 

 useful in certain respects, their value should not be over- 

 estimated, because they are indistinct wherever the specimen is 

 not even, or shows several strata. Under such circumstances, 

 photographs can hardly replace drawings made by an experi- 

 enced and conscientious observer.
