    A. communication between the Portal and Epigastric veins existing as a small branch is said by Luschka {Anal. ii. 339) to be normal in Man even when adult, and in most Mammals. He describes it under the name of “ Vena parujtMlicalis” which runs, he says, into the Portal vein alongside of the Umbilical vein. It sometimes fuses with that vein, as in Burow’s case {Muller s Archiv, 1838, p. 44) in a foetus, as in Hyrtl’scase {(Esterreichische Jahrhucher, XXVII. 6, quoted Ijy Theile) in an Anencephalous monster, and as in my case quoted above. In an exaggei’ated condition it is, I believe, somewhat rare; in- stances of its enlargement are recorded by Monro {Elements of Anatomy., 1825, II. 282, quoted by Henle, Gefasslehre, p. 388); by Rokitansky {Path. Anal. iv. 373, under the name of “Caput Medusae”); by Cruveilhier from a case of Pegot’s {Anal. Path. i. PI. 6, livraison 16, in a very exaggerated condition, beautifully drawn); Meniere {Arch. Gen. de Med. x. 381, 8), who also quotes a similar case of Mannec’s which he saw; by Serres {Arch. Gen. de Med. Dec. 1823, p. 633) ; and Sappey {Alem. de VAcad. Roy. de Med. xxiii. 270), who, however, is wrong in asserting that this vein never ]o\ns the Umbilical vein ; for it has done so in several cases quoted above, and it certainly did so in mine. In this collection of cases the amount of enlargement varied much, also the age and the absence or presence of communi- cation with the Umbilical vein. To this head ought probably to be referred a case recorded by Johannes Henricus Schulze {Dissertatio de vasis umhiliccdihus natorum et adultorum. De Johanne Henrico Schulze in Pisput. Anat. Select. V. Albertus Haller, Gottingen, MDCCL.) ; but this may possibly have been a case of regurgitation into a patent um- bilical vein—“Mortuam (inquit) secui, atque primo occurrit vena umbilicalis * * * sanguinis copia turgida atque extensa, in quibus- dam locis, ubi hsec vena contorquebatui', instar varicum tuberosa. Hepar justam habebat magnitudinem, sed erat album, tuberosum, in- sequale, durum et exsangue.” The dissection was by Volcherus Coiterus. Schiff developed artificially a varicose state of this vein by tying the portal vein in Cats {Canstatt's Jahreshericht, 1862, p. 127). From a comparative anatomy point of view this communication has, from the first times of its being observed, been compared with the Epigastric vein of cold-blooded, aii'-breathiug vertebrata, and to this we need not further allude. A lai’ge communication between the Epigastric and Umbilical veins is described as normal by Serres and Gratiolet {Gomptes Rendus, lii. 625), in a Rorqual (Baltenoptera), and they infer from the increasing size of the Umbilical vein, as it approaches the Liver, that the blood sets from the systemic to the Portal system ; this enlargement, however, may be due to Portal regurgitation. In an account of a Seal (Phoca Vitulina, dissected at Oxford, Sept. 1862, and described in a note-book there), I find that the Umbilical vein was open to within half-an-inch of the Umbilicus, but I cannot ascertain whether it was enlarged. The development of the Allantois throws the greatest light on this connection between the veins of the anterior abdominal parietes
