densely infiltrated with lymphoid tissue. At 32 weeks the vermiform appendix of man is to all appearances an actively functional gland. There are, then, to be met with in the plane of a transverse section from ten to 12 well-marked and large lymph follicles and about 160 tubular glands. The conclusion to be drawn in regard to the first point is, then, that whilst there is no lymphoid tissue in the cagcal apex of the lower animals or in the appendix of man at the time of birth the portion of gut under consideration has become within a period of from one to six weeks an actively functional lymph gland. In regard to the second point the writers entertain no doubt that the lymphoid tissue does tend to disappear from the human appendix, for the number of lymph follicles visible in transverse sections of appendices will be found to become less numerous with advancing age, so that whilst six or seven follicles may be found in a transverse section of an appendix up to the age of 40 years, at the age of 60 years and above there are only traces or a total absence of them. The lymphoid tissue, however, never totally disappears. Lastly, they consider that obliteration of the On these vermiform appendix is a pathological process. various grounds the vermiform appendix of man may be regarded as by no means a vestigial remnant or an organ in a state of retrogression but as an actively functional lymph gland. The writers consider that the passage of inert foreign bodies into the appendix is extremely rare, though the entrance of living organisms such as the trichocephalus is easily conceivable and has been several times demonstrated in cases where appendicitis was present.

Not for the first time has THE LANCET1 borne testimony to what Italy and the outside world owe to the clinician and pathologist who has worthily held up the torch transmitted from Baglivi to Morgagni and from Morgagni to the modern schools.
