NH2(CaHeN)Pd.Cl, and NH(CsHs)(CaHsN)Pd.Cl. An anilin com- 
pound corresponding to the first of these was also obtained ; its chlorid 
is represented by NH2(C12H7)Pd.Cl— Ann. der Chemie und Pharma- 
te, Ixxxvi, 341. 
2. Anthranilic and Benzoie Acids. —GERLAND has instituted an accu- 
rate comparison of these acids, which together with a third acid dis- 
covered by Chancel, are represented by the formula C14 He NOs+HO. 
The results of this investigation are as follows. 
(1.) Anthranilic acid is the true carbanilidic acid constituted simi- 
larly to carbonic acid and represented by the rational formula COz, 
CO(NH.C12Hs)+ HO. 
(2.) Anthranilic acid is different from benzamie acid and from the 
acid termed by Chancel carbanilidic acid. : 
(3.) Benzamic acid C1sHs(NH2)Os+HO is identical with Chan- 
cel’s carbanilidie acid. 
.) Nitrous acid NOs converts anthranilic acid completely into 
salycylic acid ; the equation is C14HeNOs, HO+NOs=C14Hs0s,

3. New Compounds of Iridium.—Sxosuixorr has discovered a class 
of ammoniacal componnds of iridium which exhibit a perfeet analogy 
to the well known platinum bases of Gros and Reiset. The investiga- 
the green salt of Magnus. ‘Treated with hot nitric acid this substance 
ds 
tained which is the chlorid of a new base corresponding to Reiset’s 
platinum base, and having the formula NoHe.IrCl or NH2(NHs yIrCl. 
The author obtained a crystalline sulphate and nitrate of this base, hav- 
ing the formulas NH2(NH4)IrO, SOs and NH2(NH4)IrO, NOs. The 
perfect parallelism between these bases, and those containing platinum 
and palladium is very interesting, and it is to be hoped that rhodium, 
ruthenium, and osmium will be studied from the same point of view.—
