American journal of pharmacy . a C10HlfeO2, half of which exists inthe free state and the rest as a geranyl ester.—Ibid., 1898, p. 217. Am. Jour. , 18! 9. Notes and News. xvii NOTES AND NEWS. Abnormal Development of a Rattlesnakes Fangs.—The photographwhich is presented herewith was sent to the Scientific American by Dr. , of San Antonio, Tex., and is a life-like representation of the head ofthe much dreaded rattlesnake, the Crotalus horridus. The following descrip-tion appeared in the March 25th issue of the aforesaid publication, to whom weare also indebted for the loan of the cut. The original reptile was a very largerattlesnake, and was killed by a friend of Dr. Menger in the hills of Helotes,about eighteen miles northwest of San Antonio. The rattles and the head ofthis snake were presented to him and he prepared the fangs, etc., to show theirrelation to the poison glands. The head was supplied with four fangs, two fullgrown and two others near them in the front region of the upper jaw. The. exposure was taken by lamplight. The fact of the snake having four fangs isinteresting. In all rattlesnakes there are, besides the poison fangs, rudimentaryfangs which, upon the loss of the old fangs, develop and supply their place. Inthis case, however, the development has been abnormal, and the second pair offangs have developed before any loss of the old fangs has been sustained. Solder for Glass.—A metallic compound which firmly adheres to glassesobtained by melting together 95 per cent, (by weight) of tin and five parts ofzinc. The M. P. lies at about 2000 (C?) and the compound is spread upon theglass previously heated to this temperature, by means of a soldering iron. Afterit cools it adheres firmly to the glass. Another alloy, consisting of nine parts oftin and one part of aluminium may be used, but the M. P. is higher (about 3900).—Scient. Amer., 1898, p. 230, from Gold u.
