RELATION OF CHLORAL, TO STRYCHNINE. 



Not long ago we were informed by Dr. Liebreick that hy- 

 drate of chloral might be considered as a perfect antidote to 

 strychnine ; but Dr. Ore announces, as the result of an elab- 

 orate series of experiments recently communicated to the 

 Academy of Sciences of Paris, that this statement is entirely 

 erroneous, and that strychnine and chloral have no such rela- 

 tion to each other, but that they rather co-operate to produce 

 an injurious or even fatal result. 6 B, July 22, 1872, 218. 



CORALLINE NOT POISONOUS. 



Some time ago it was stated in English journals that coral- 

 line is poisonous, and it was asserted that cutaneous eruptions 

 have been caused by wearing clothes dyed with it. On the 

 other hand, however, the opinion has been advanced that such 

 diseases, if really occurring, have probably been originated 

 by arsenious mordants, and not by the dye-stuff, as many and 

 careful experiments have shown that coralline itself is innox- 

 ious. 25 C, 1872, xii. 



lieurnur's system of closets. 



Lieurnur's system of cleaning cities has lately been tested 

 in Amsterdam over an area of four streets, with 207 houses, and 

 has given entire satisfaction. Hereafter all privies in a given 

 district in that city (which may contain 20,000 to 25,000 inhab- 

 itants) are to be brought in connection with a large reservoir 

 by means of iron pipes, and the foecal matter conveyed into 

 this reservoir by an air-pump, and thence in a similar manner 

 into iron cylinders, which are then carried off to their place 

 of destination. 28 C, v, May, 1872, 313. 



DISPOSAL OF SEWAGE. 



A communication to the English 3fechcmic, discussing the 

 sewage question, which is always a serious problem, urges the 

 great importance of receiving such matter into a mixture de- 

 vised by the writer, and which, in his opinion, contains the in- 

 gredients of the utmost value in agricultural economy, and 

 which, when united with foecal matter, will prove to be a 

 manure of extraordinary value. The mixture is composed of 

 the following ingredients: Perfectly dry humus or soil, 100
