THE WORK SHOP. 



Demonstrators and students can easily construct in a 

 shop, many pieces of simple apparatus, which if pur- 

 chased of some instrument house, would amount to many 

 times the cost of the material and would deprive students 

 of some very valuable experience. Frog, rat, rabbit and 

 dog holders may be made, the tambour frames may be 

 furnished with membranes and mounted as receiving or 

 recording tambours, cardiographs, or stethographs. All 

 writing levers, electrodes, etc., should be made by the 

 students. A room with bench and vice and $25 for car- 

 penter's and machinsts' tools would be an ample start.
