lO 
as Wieland^), in a work on pseudo nitrosites, has recently demon- 
strated. The latter attributes the following formula to the pseudo 
nitrosite of anethol: 
/OCH3 
^CH — CH — CH3 
I I 
(N,0,) NO2 
CH — CH — CH. 
I 
OCH3 NO2 
It is formed when a solution of anethol in glacial acetic acid is 
treated at much reduced temperature with sodium nitrite. When boiled 
with alcohol, it becomes isomerised into the oxime of anisyl nitro-ethyl 
ketone (melting point 187°), whilst treatment of the pseudo nitrosite 
with alcoholic ammonia, or better with alcoholic caustic lye, in the cold, 
produces ^-nitro-anethol (melting point 48°). If, in producing the pseudo 
nitrosite, the mixture is not treated at a temperature low enough, there 
is formed anisyl methylglyoximeperoxide of the melting point 97°; 
and if the reaction-temperature is allowed to increase to 50^ to 60°, 
the amphi-dioxime of anisyl methyl- i, 2-diketone (melting point 206°) 
is also formed. 
Apopin Oil (Shu-yu). In our last Report 2) we published the 
translation of a treatise on this oil by Keimazu which had appeared 
in Japanese language. A further communication by the same author, 
published in thejourn. of the pharm. Soc. of Japan, No. 258, August 1903, 
is reproduced below, in abbreviated form, but in part literally translated: 
I have already reported on my examinations of some constituents 
of shu-yu, and will now communicate some results of the continuation 
of this work. 
I. Detection of formaldehyde. 
When washing the oil with water, I was struck by the strong pungent 
odour of the aqueous portion, the cause of which I was able to detect, 
by the usual reactions, as being due to the presence of formaldehyde. 
The fact that it was question of formaldehyde, and not of some other 
homologous aldehyde, was proved by the positive result of Rimini- 
Vitali's reaction. 
II. Detection of pinene. 
The liquid obtained by the fractional distillation of shu-yu at 
155° to 160°, has the specific gravity 0,8812 (16°), and the rotatory 
Liebig's Annalen 329 (1903), 225.
