Beckmann, Ber., 1886, 1 9, p. 9 8 9; 188 7, 20, p. 2580), yielding as final products an acid-amide or anilide, thus: RC(:N OH)R'-RC(OH) :NR' ---> As regards the constitution of the oximes, two possibilities exist, namely >C: NOH, or > C' ?, and the first of these is presumably correct, since on alkylation and subsequent hydrolysis an alkyl hydroxylamine of the type NH 2 OR is obtained, and consequently it is to be presumed that in the alkylated oxime, the alkyl group is attached to oxygen, and the oxime itself therefore contains the hydroxyl group. It is to be noted that the oximes of aromatic aldehydes and of unsymmetrical aromatic ketones frequently exist in isomeric forms. This isomerism is explained by the HantzschWerner hypothesis (Ber., 1890, 23, p. II) in which the assumption is made that the three valencies of the nitrogen atom do not lie in the same plane.
The isomerism of the oximes of unsymmetrical ketones is explained in the same manner, and their configuration is determined by an application of the Beckmann transformation (see Ber., 1891, 24, p. 1 3); thus: R C R' - R C(OH): NR'-->R Conhr'(R' and OH, " syn ").
Then, since nr rl is also a rational integral function of n of degree r, we can find a coefficient c r, not containing n, and such as to make N-c r nr ri contain no power of n higher than n r - 1.

Harries (Ber., 1895, 28, p. 1223) has also shown that as-phenylhydrazino-acetic esters, when heated with formamide and substituted formamides under pressure, yield dihydrotriazines: CO 2 R CO-NR'-CH H2 N(C6H5)NH2 +R'NH CHO --> CH 2 N(C 6 H 5) IV The phen-a-triazines are yellow-coloured crystalline compounds of a somewhat basic character.

With benzene sulphochloride in the presence of alkali, the primary amines yield compounds of the type C 6 H 5 S0 2 NHR, soluble in alkalies, whilst the secondary amines yield compounds of the type C 6 H 5 S0 2 NR 2, insoluble in alkalies (0.

In the case of a recurring continued fraction which represents N, where N is an integer, if n is the number of partial quotients in the recurring cycle, and pnr/gnr the nr th convergent, then p 2 nr - Ng2nr = (- I) nr, whence, if n is odd, integral solutions of the indeterminate equation x 2 - Ny 2 = I (the so-called Pellian equation) can be found.
If r be the number of quotients in the recurring cycle, we can by writing down the relations connectin g the successive p's and q's obtain a linear relation connecting p nr +m, t'(n-1)r +m, +m in which the coefficients are all constants.
