 Holmes, E. — Drawing from the Microscope. 



[Remarks on E. T. D. supra, and suggesting that with the neutral tint 

 reflector " he has but to turn his slide over, i.e. cover downwards on the 

 stage, to make his outlines, and then put his slide right way up when he 

 fills in his detail freehand."]

 Holmes (0. W.) Dr., and the Microscope. 



[In a recent speech, in illustrating the microscopical facilities of the Harvard 

 Medical School, he said : — " A man five feet high, enlarged to correspond 

 with the Microscope power used, would be a mile high, would weigh 

 120,000,000,000 lbs., and could pick up the Boston State House and 

 chuck it into the sea, cleaning out that ancient structure by a summary 

 process which would put to shame the exploits of Commodus and his 

 kind."]
