this plan for six weeks, he was restored to perfect health. 

 The patient is now before mc, Sept. 14, 180.5 ; and in 

 excellent health, looks well, is fat, has since had no com- 

 plaint of any kind, and is an additional proof of the virtue 

 of the aerial remedy. 



I have the honour to remain. 

 Dear sir, Sec.

Observations on this Case. — The same opinions arise liere 

 as in other cases : but the pneumatic practice is more par- 

 ticularly necessary, as ionics would only augment the 

 malady, if applied alone, as the lungs are locally inflamed ; 

 and the lowerinc; plan would only have aided the debility 

 induced from this local cause, exciting an immoderate mor- 

 bid secretion from the lungs. 



LIT. A simple Method of making Tulcs of elastic Gum or 

 Caoutchouc, to avoid the Expense of Solution in JEther. 



ibpLiT a stick of cane, and then apply together again the 

 split pieces, but with a slip of whalebone interposed be- 

 tween them. Cut the elastic gum into slips fit for twist- 

 ing over the prepared cane, so as to cover it ; then, by duly 

 heating the surface of the cane covered with the caoutchouc, 

 it will melt so as to form one piece. When cold, draw out 

 the interposed whalebone from between the split cane; by 

 which means, without difficulty, the whole substance ot the 

 cane may then be readily withdrawn from under the cover- 

 ing, thus leaving the tube formed as desired. 



Some recommend - winding small thread round the 

 twisted gum clastic, to help to unite the joinings, and em- 

 ploy the heat of boiling water.
