at the opposite jugular in an interval of from twenty to 

 twenty-five seconds. It arrived in twenty-three to thirty 

 seconds in the opposite external thoracic vein, in twenty 

 seconds at the large saphena vein, in fifteen to thirty seconds 

 in the masseterine artery ; in ten to fifteen and in twenty to 

 twenty-six seconds in the external maxillary artery, and from 

 twenty to twenty-five and from twenty-five to thirty seconds 

 in the artery of the metatarsus, in each case on the side op- 

 posite to that of the injection. Experiment by E. Herring,

39. Remarkable phenomenon in a medicinal compound. — 

 M. Ehrenberg, apothecary at Cannern, having, agree- 

 ably to the prescription of a physician, made a solution of 

 acetate of potash in cinnamon water, found twenty-four 

 hours afterwards, that the solution exhaled a decided odor 

 of hydrocyanic acid. Thinking that some mistake had 

 been made in the preparation, he renewed it and obtained 

 the same result. M. Blei, apothecary at Pemberg, has also 

 confirmed the fact. — Fer. Bui. Sep. 1828. 



40. Discovery of iodine in the ore of zinc. — It is known 

 that M. Vauquelin is the first who discovered iodine in the 

 mineral kingdom. He found this simple substance in some 

 silver ores from the neighborhood of Mexico, and according 

 to M. Del Rio, these mineral are found in the province of 

 Zacatecas. M. Bustamente has since found indications of 

 it in an ash colored lead ore, from the mines of Catorce. 

 Lastly, M. Mentzel has just proved the presence of iodine 

 in an ore of zinc from Upper Silesia. — Fer. Bull. JVbx). 1828. 



41. Size of the grains of native plaiina. — The cabinets 

 of Europe scarcely contained any grains of native platina 

 larger than a line in diameter until M. Humboldt brought 

 one from South America weighing 1088 grains. This was 

 the largest known until 1 822, when the Museum of Madrid 

 was enriched with a native specimen two inches and four 

 lines in diameter, weighing eleven thousand six hundred 

 and forty-one grains, obtained from the gold washings of 

 Condoto. But these have been outdone by a mass from the 

 mines of Demidoff, in Oural, proved by Professor Lubarsky 

 of St. Petersburgh, in 1823, to be native platina, containing 

 an alloy of iridium and osmium. It weighs four thousand
