Abstract

It is pointed out that a singularity-free cosmological perfect fluid solution given recently by Mars had previously been obtained by Letelier. Generalizations of this solution which remain singularity-free are also presented. A specific example is given which includes an incoming and outgoing acoustic and gravitational pulse.
