“…The roots of (22) are conveniently obtained from the double QR iteration of Francis, which is particularly simple for matrices of Hessenberg form [14]. In order to analyze our functionf (A) in a way similar to the previous section, we determine its first logarithmic derivative (the higher logarithmic derivatives may be simply obtained, by repeating this procedure): The question of the nature of the poles of the Pade approximants is a subtle one.…”

A procedure for summing a power series based on a Darboux function ansatz is developed. It involves computation of poles and residues of logarithmic derivatives using rational functions. Applications to the helium isoelectronic sequence condense the power series expansion (-40 coefficients) to a few-parameter formula, which exhibits the singularity determining the radius of convergence. Accurate extrapolations of electron affinities and shielding factors are obtained.

This review continuesfrom the close of the previous review on Biochemical Analysis (131) to December 31, 1963. The same philosophy also prevails, namely that developments, trends, and potentialities will be emphasized rather than routine applications and minor variations of recognized procedures. Such arbitrary and discriminating practice therefore overlooks many fine contributions that are concerned with the consolidation of information in their field of interest. This is not to disarm criticism in advance, which is futile, but to give some rational explana-

“…A simple apparatus for liquid-solid extractions was described (63) and the design of automatic trace analyzers was discussed (123), with emphasis on continuous analyzers for such things as oxygen, carbon dioxide, sulfide, chloride, iodide, and hydrogen ion concentrations. In a general review of developments in microchemical equipment, Francis emphasized new instruments to be used for automatic operations (67).…”
