Examining these sections under a microscope, they discovered thousands of microfossils of individual and paired cells, some long and thin, others flat, wrinkled or folded, but all similar to those found...

Almost invariably, he reports, the technique stops headaches. Still another imaginative treatment has been introduced...

Says Elkind: "The better the relationship is, the more successful the results are likely...
