ordinary washing of clothes, the process consisting in laying 

 the fabrics in a solution of one part of glass and twenty to 

 thirty of water at a temperature of 100 to 150 Fahrenheit, 

 and allowing them to stand several hours, when they are to 

 be stirred around with a stick, the bath having been pre- 

 viously heated up by the addition of warm water. The 

 clothes are then laid upon a board or over bars to drain, 

 when the liquid coming from them will be found to contain 

 nearly all the dirt. After this, treatment in the ordinary 

 way, with a very little soap, will quickly remove any remain- 

 ing impurity. It is recommended to place the clothes a sec- 

 ond time in a weak solution of water-glass one part in fifty 

 and finally to rinse out with warm water. Clothes thus 

 treated, it is said, become of a dazzling white, and do not 

 need bleaching. 9 C y May, v., 33. 



CAKBOLIC ACID AND RINDERPEST. 



Dr. Hope, in a communication to the British Association, 

 stated the result of certain experiments upon cattle with car- 

 bolic acid during the rinderpest pestilence in 1867. Of about 

 270 cows under his charge the majority were attacked by the 

 disease, but by injecting a solution of carbolic acid, either 

 through the mouth or rectum, he was enabled to recover 111 

 of them. The remainder, not so dealt with, died or had to be 

 slaughtered. For this reason, he argued that the chemical 

 treatment of contagion is much better than the medicinal, 

 both in respect to man and adult animals. 8 A, October,

LA PLATA OR CARNO GUANO. 



The residuum of the flesh used in the establishments of 

 Buenos Ayres for the purpose of preparing Liebig's extract 

 of meat is now to be met with in commerce under the name 

 of La Plata or Carno guano, and is recommended very highly 

 as a manure. Analysis shows that this contains nine parts 

 in one hundred of water, forty-one of organic matter, nineteen 

 of lime, magnesia, oxide of iron, etc., ten of phosphoric acid, 

 from one half to one part of potash, and the rest of insoluble 

 matter, such as sand, clay, etc. The nitrogen amounts to 

 nearly six per cent. 6 (7, August 10, xxxn., 318.
