lowed by a table of the essential oils, giving the name of the oil and 
the part of the plant from which it is obtained, the botanical source, 
the percentage yield from the raw material, with various physical and

anists generally, we think. It may doubtless be obtained from the 
New York house on application. 
IN THE “Wilder Quarter-Century Book,” a collection of original pa- 
pers dedicated to Professor Burt G. Wilder, at the close of his twenty- 
fifth year of service in Cornell University, by a number of his old stu- 
dents, appears a paper on the genus Phyllospadix, by Professor W. R. 
Dudley. This genus of marine Potamogetonacez consists of two spe- 
cles growing on our Pacific coast, and is believed by Prof. Dudley to 
bea comparatively recent offshoot of Zostera. This paper deals “with 
the morphology, anatomy and environment of the genus in relation to 
tts probable origin.”
