ETHYLATE OF SODIUM. 



DR. BENJ. W. Richardson of London uses this preparation with 

 marked success is removing diffused nsevi, tattoo marks, etc. 

 By applying it to the pedicle of a nasal polypus, the growth, a 

 small one, was removed at once by blowing the nose. Larger 

 polypi have been removed by two or three applications. In ozaena 

 and lupus he reports most excellent results. 



CITRIC ACID FOR IMPURE WATER. 



DR. Langfeldt has made a series of experiments which show that 

 one part of citric acid in 2,000 parts of water containing animal- 

 cules will, in about a minute, cause the death of the animalcule, after 

 which they settle to the bottom of the vessel. The solution should 

 be fresh. 



PAMPAS GRASS. 



THIS wonderful western cereal, which is commonly called Pam- 

 pas grass, according to the Philadelphia Trade Jourtial, con- 

 tains more starch and less oil than corn, which renders it valuable as 

 a malting agent, and the Western brewers are going to use it in the 

 place of barley.

 to the nape of the neck and along the spine large pieces of flan- 

 nel dipped in hot wa^er of a temperature just bearable to the hand,
