DECEASE OF DR. YOUNO AND SIR HUMPHRY DAVY. 



IT is our melancholy duty to record the loss of two of our most 

 distinguished cultivators of science, Dr.Thomas Young, and Sir 

 Humphry Davy: Dr. Young died in Lctndon on May 10th, and Sir 

 H. Davy, at Geneva, on May 29th. The most important of the 

 discoveries and contributions to science of both, have been from 

 time to time recorded or inserted in the Philosophical .Magazine ; 

 and we have commenced the present Number with the last produc- 

 tion of Sir H. Davy, A paper on the Electricity of the Torpedo. 



SPONGY PLATINA. 

 M. Pleischel recommends that a piece of paper be imbibed tliree 

 times in succession with a solution of muriiite of plalina, and then 

 burnt. The residue is the platina, he says, in its best state for efl'ect- 

 ing ignition. We have always found that, when prepared by heating 

 a little pure ammonio-muriate of platina ujjon jjlatina foil in a spirit- 

 lamp, at a temperature as low as possible, so that it be sudicient to 

 dissipate every thing volatile, then the platina would iiillame a mix- 

 ture of oxygen and hydrogen at the lowest possible temperature.
