30. A Carpet has been inanufactured at the Royal estab- 

 lishment of the Savonnerie at Paris, destined for the Hall 

 of the throne, which is believed to be the largest that has 

 ever been executed. It is 50 feet long, and 30 wide, and 

 might have been done in one peice agreeably to the de- 

 sign, but it would have required in that case, 9 years for 

 its execution. For the sake of greater expedition it was 

 divided into three parts which have been accomplished in 

 three years. Agreeably to the details that have been fur- 

 nished, it has cost in labour alone 50,000 francs, (|1 0,000.) 



31. Iodine as a Medicine. We have already stated the 

 beneficial results which M. Coindet had obtained in em- 

 ploying Iodine in the treatment of Goitre ; but then this cu- 

 rious substance was administered internally, and we have 

 had occasion to remark that in some cases, unpleasant 

 symptoms were produced by the local action of the Iodine 

 upon the mucous membranes of the stomach. The same 

 pLysician has since tried to introduce this substance into 

 the animal economy by simple friction, and he announces 

 a success equal to the former. Twenty-two patients of 

 diiferent ages and sexes, have been treated by this new 

 process. They had all very large goitres ; more than one 

 half of them were completely cured in the space of from 

 four to six weeks, and the others in a greater or less degree. 

 The ointment which Dr. Coindet employs, is composed of 

 half a gros of hydriodate of potash with ij oz. of hogs 

 lard. The part is rubbed morning and evening with a por- 

 tion of ointment as large as a nut, until the whole is ab- 

 sorbed. 



Dr. Coindet states that he has used Iodine in the treat- 

 ment of scropula, ''with a success which surpassed his 

 hopes." — An. de Chim. 



32. The Muriate of Copper and Nitrat of Soda of Peru 

 — From a statement made by M. Mariano de Rivero, a Pe 

 ruvian, it appears that the muriate of copper, so much ad- 

 mired for its fine colour, is found in large quantities in the 

 district of Tarapaca, in the gold and silver mines. It ac- 

 companies the ore called Yahicoia, and is found in veins, in 

 such quantity, as to give rise sometimes to extensive work- 

 ings. The Indians of Atacama extract it, grind and sift it, 

 and sell it in the state in which we see it. They call it
