568 Jealousy in a Dog. — Collecting Swallows' Nests. 



Jealousy in a Dog. — A wood-dealer residing near Quai St. 

 Michael, Paris, had a fine English bnll-dog, which was a 

 great favourite of his wife, who used to caress the animal. 

 On the 10th of August last she was sitting not far from the 

 kennel caressing her child, which was five years old. The 

 dog became jealous of it, and at last so furious that he burst 

 his chain, rushed at the child, worried it, and did not quit 

 his hold, until he was killed with a knife. The child was so 

 severely hurt, that its life was despaired of. — Id. 



New hot spring at Carlsbad. — The subterraneous hot 

 water of Carlsbad has found a new issue in the square of 

 that town. Two talented young chemists, Dr. Wolf, and 

 Mr. John Knewkowsky, have analyzed the water of this new 

 spring, and have found in it both bromine and iodine, the 

 presence of which elements in the waters of Carlsbad was 

 first discovered by Professor Pleisdel. — Id. 



Hybernation of the Marmot. — Mr. Bonafont, of Geneva, 

 has made a few experiments with reference to the hyberna- 

 tion of the marmot. Having procured four specimens, he 

 exposed them suddenly to a temperature of — 10° cent. ; but 

 the impression was so strong and painful that they did not 

 fall asleep. The cold being diminished, three fell asleep, 

 whilst the fourth escaped. A fortnight after, a servant was 

 sent to fetch something from a deep cave, but was unable to 

 open the door. It was found necessary to break it, when 

 there was found behind it a high heap of rubbish. The 

 marmot had converted the cave into a sort of fortress ; it had 

 entered through an opening in the vault, and barricaded the 

 door with the earth it had dug up, as well as with mortar 

 which it had scraped from the wall. It was found asleep 

 in a corner, on a bed of soft straw, 8 — 10 inches thick, which 

 it had unrolled from more than twenty bottles. That its 

 repose might not be disturbed by the rats, it had erected 

 around its couch a double wall of fragments of bottles, which 

 the rats could not surmount. — Id. 



Collecting the Nests of the Hirundo esculenta. — (Ex- 

 tracted from the letter of a German, dated Karambolang, on 

 the South coast of Java, 26th March, 1838.) " For the last 

 week our place has become very busy, as this is one of the 

 seasons when the nests of the swallows are collected, which 

 is repeated every 100 days. On these occasions we receive 

 the visit of a few civil officers, with numerous attendants, 

 from Pruworedjo, who give the necessary orders for the har- 

 vest and superintend it. Coolies must be furnished from the 

 neighbourhood for that dangerous task. The place where 

 the nests are found is about half a league distant from here.
