It is shown that the recent theory by Doniach and Engelsberg to emphasize the effect of spin fluctuations for description of nearly ferromagnetic Fermi liquids is not compatible with experiment for liquid He3, when the renormalization effect is rightly taken into account. One of their conclusions that the spin fluctuations do not influence the susceptibility is also shown to be unreasonable. The observed low temperature variation of the specific heat in a Fermi liquid, He3, can be explained, without the concept of the spin fluctuations, through the individual quasi-particle excitations correlating with collective oscillations and other quasi-particles.
