The Review of Reviews. 



TYye St^el Tl^ioKer. 



When you talk about labour-saving machinery, you generally mean labourer- 

 saving machinery, don't you ? You mean machinery which substitutes steam ])0\ver 

 for muscle power, or mechanical speed and precision for manual dexterity. 



But manual labour is the cheapest kind of labour. 



Did you ever hear of a machine that could save brain-labour ? A machine 

 which, within limits, can think ? 



There is such a machine. It is called the Rrunsviga Calculator, but do not let 

 the name mislead you. You know all about adding machines, but this is not one of 

 them. With brains of steel it performs every operation of arithmetic. 



Its Tbougbts. 



It works out multiplications and divisions, proportions, rates, percentages, 

 everything. It is quite indifferent to the subject matter, It will take on an invoice 

 extension or a length note, a timber calculation or a currency conversion with 

 equal readiness. 



It will give you the result in a quarter the time that a human reckoner would 

 take. And it cannot make a mistake. Its mind never wanders; it never forgets a figure 

 or makes a slip in its multiplication table. 



Instead of saving the time of the ISs. a week man, it saves the time of the /4, 

 /,'5, and ^50 a week man.

It is a little desk instrument, handsome to look at and handy to use. 



The special light model is called the Brunsvigula. It weighs 7 lbs., is the size 

 of a small hand camera, and works in a whisper. 



There are 2(),()00 Brunsvigas in use in the world. This is what one firm sa\s 

 of it: — 



"The Brunsviga Calculator Machine did in exactly 3,'j minutes, absolutely 

 correctly, certain jiro-rating which our fastest accountant could only accomplish 

 in VS minntt's of solid work."

If you like we will send a man with a machine to your office to work test 

 calculations for you.
