Professor Wm. I. Marshall, of Fitchburg, 

 Mass., who will be remembered by our citi- 

 zens from his very entertaining lecture upon

Henry B. Dawson, editor of the Histori-

 ing notice in a private lette : 



Dear Sir : — I have received the January 

 1881, number of your Review, which I have 

 spent an afternoon in examining; and I am 

 very much pleased wiih it. I fear it is too 

 good to be "popular," and that it does not 

 pay. 



The British government has recently order- 

 ed from the Brush Company of Cleveland, 

 Ohio, an electric light for use in the navy, of 

 100,000 candle illuminating power. It is 

 believed to be the most powerful light ever 

 .made by human hands. 



At the meeting of the St. Louis Academy 

 of Science April 4, Dr. Stephens reported 

 upon his examintion of the famous fragments 

 of matter, supposed to be human bones, 

 which were found by Dr. R. W. Boothe in a 

 mine sixty miles from there, at a greater 

 depth than human remains were ever found 

 before, in a deposit of iron. He expressed 

 a decided opinion that there was nothing in 

 the structure of the fragments to demonstrate 

 that they were bones, and he was positive 

 they were of vegetable growth. 



Prof. H. S. Short, of the Denver Uni- 

 versity, is said to have made two very im- 

 portant discoveries in electrical illumination : 

 first, that a film of chromium can be made 

 with the best conductive capacity and prac- 

 tically indestructible ; second, that the film 

 may be heated by the electric current to the 

 most brilliant incandescence in a globe filled 

 with hydrogen gas, without injury to either 

 the chromium or the gas, thus overcoming 

 the chiiif difficulties with which Edison is 

 contending. 



The extensive works of the Kansas City
