Nelson, Burt E., describes and illustrates some of the characteristic

Velardi, G. (Bull. Chim. farm., 1906, pp. 65-67), concludes that 
at 103° the emulsin contained in bitter almond loses its activity. 
(2) At 170° only, one may be certain of the nontoxicity of bitter 
almond, because parting with amygdalin at that point it is incapable 
of producing hydrocyanic acid under the action of ferments. (3) 
Heated slowly amygdalin undergoes chemical transformation at 
180°. — Abstr. in Bull, des sc. pharmacol. , Par., 1906, v. 13, p. 518. 
Fyfe, John William, says that Amygdalus communis was a favorite

Drug., Bond., 1906, v. 69, p. 862. 
Herissey, H., commenting on the Ph. Ndl. IV standard of at 
least 80 per cent for amyl nitrite, remarks that it is not always easy

product; a method of analysis is given. — J. de pharm. et de chim., 
Par., 1906, v. 23, p. 480. 
Wells, G. Harlan, says that three to five drops of “ amyl nitrite ”

amyl nitrite causes relaxation of the bronchial muscles. — Compt. 
rend. Soc. biol., Par., 1906, v. 61, p. 522. 
Pic and Petit jean maintain that, parallel with the vasodilatation 
in the general circulation, amyl nitrite causes a vasoconstriction in 
the pulmonary circulation, as is indicated by (1) the elevation of 
pressure in the pulmonary artery, and (2) by a change of color 
(pallor) of the lungs. — Ibid., v. 60, p. 131.
