It is evident that we may have tones of frequency hn 1 kn 2 hn i - kn 2 hnl+kn2, where h and k are any integers.
H HN CEH?Chch C(Ch3)N.Cs The ketonic esters under like treatment yield oxypyrimidines, whilst if cyanacetic ester be employed then amino-oxypyrimidines are obtained.
The magnetization at any point inside the ellipsoid will then be I = HN (29) where N=47r (e2t) (-2-eloI- e - t), e being the eccentricity (see Maxwell's Treatise, § 438).
