~enia denotes nitride of -ene: Example—Deutenia=C? H®’ N=nitride of deutene 
(acetylamine, Natanson and Cloez). 
-isia denotes nitride of -ise: Example—Deutisia=C? H* N=nitride of deutise= 
acetonitrile, 
The vowels a, e, 2, &c. before a functional termination denote respectively the 
replacement of H? by O, H+ by O?, H® by O5, &c., as deutyl C* H®, deutayl C* H* O, 
deutene C? H4, deuteéne C* O?. 
The acids derived from the hydrates of -yl, -ene, and -ise, respectively, by the 
replacement of H? by O, are -ie acid, -eric acid, -isic acid: examples, penteptic 
=C’ H® 0?=benzoic, pentepteric=C’ H® O8=salicylic. 
The acids derived from the alcohols by the replacement of H4 by O%, or from the 
last-mentioned acids by the replacement of H? by O, are respectively, -aic, -eraic, 
-isaic; examples, nonaic = C? H'6 0? = coumaric, noneraic = C® H!* O4 = anchoic, 
tetreptisaic=C’ H*®O'=pgallic. ~ 
The acids formed by the replacement of H® by O%, are -eic, -ereic, -iseic: 
examples, tritocteic=C*® H’ O1=orsellic, tritereic=C* H?O0°=mesoxalic, deutexiseic 
=C* H*® O%=aconitic. The names of the unibasic acids therefore terminate in -ic, 
-aic, -eic; those of the bibasic acids in -eric, -eraic, -ereic; and those of the terbasic 
-acids in -isic, -isaic, -iseic. Chlorine, bromine, and iodine substitution products 
are denoted by the syllables chlo-*, bro-, io-, prefixed to the names of the hydrogen 
compound from which they are derived; as chlodeutene=C? H3Cl, brotetrexia= 
C°H BrN=bromaniline. Multiplication is in all cases expressed by Latin numerals; 
as terchlodeutic acid—=C? HCl? O?=(trichloracetic), biprotylia (or biprotia)=C? H7 N 
=dimethylamine. 
Tn devising these names, the author has tried to avoid using expedients which are 
not recommended by being already partially in use amongst chemists. It is evident 
that the system of nomenclature proposed is very far from complete: it is intended 
only as a suggestion of the way in which a more complete system might be formed. 
The authox’s object has been to propose rules by which intelligible names may be given 
to new bodies, not to improve on those already attached to known substances, 
On some Arseniates of Ammonia. By ALPHONSE GAGES. 
After mentioning the arseniates of ammonia already described by Berzelius and Mit- 
scherlich, and noticing the imperfect description given in books about the processes 
for preparing the salts of arhmonia and arsenic acid, and the doubtful character of 
their constitution, the author described his own experiments, which verified the 
constitution of the salts mentioned by Berzelius and Mitscherlich: he found, how- 
ever, that the salt containing three equivalents of ammonia described by the former, 
contains seven equivalents of hydrated water, He described three new double salts, 
formed by arseniate of ammonia, in which soda, potash, &c. act as the second bases. 
He also exhibited some beautifully crystallized compounds of arsenic acid, with mor- 
phia and quinine, which may probably be of interest as therapeutical agents, 
On the Specific Gravity of Chloride of Nitrogen, with some Remarks upon 
its Action on Alcohol. By ALPHONSE GAGES. 
The author gave determinations which were extremely close to those given many 
years ago by Sir Humphry Davy. He also mentioned the fact that chloride of nitro- 
gen dissolves in absolute alcohol without decomposition, but if the solution be allowed 
to stand for a few hours it decomposes. He described an apparatus for introducing 
the chloride of nitrogen into the alcohol, and mentioned the character of the reaction 
which took place. 
Chemical Notes. By J. H. Guapstone, Ph.D., F.R.S. 
1, On Explosive Potassium.—Dr, Gladstone related how on one occasion a piece 
of potassium had exploded in his hands with much flame, noise, and violence. On 
examining the specimen afterwards, he found that it contained hard pieces which con- 
sisted of the compound of carbonic oxide and potassium, and were convertible by
