[ From the French .] [This memoir originally appeared in the Gazeta Medina da Bahia for September, 1877 ; the French translation, from the Portuguese, being afterwards published in the Archives de Medecitte Navalc for December, 1877. The full title runs : — “ New phase of the question relating to the parasitic nature of Chyluria. Discovery of the adult repre- sentative of the ‘ Filaria of Wucherer.’ Par le Dr. Da Silva Lima, Medicin de l’Hopital de la Charite de Bahia.” — Eds.] Those of our readers who have followed the progress of the discussion which has arisen during these last years, as much in our country as elsewhere, on the subject of chylous haematuria will, without doubt, learn with great interest a very important fact which has come to us from Australia, and which seems destined to dissolve the problem, so laboriously studied, of the pathology of this disease. This fact is nothing less than the discovery of the pro- genitor or parent worm of the microscopic Filaria? found, for the first time, by Wucherer, at Bahia, in chylurous urine, and since then by divers observers in other tropical regions, not only in the urine, but also in the blood of patients affected with elephantiasis and certain diseases of the skin. But, before relating this fact, which comes to us accom- panied with commentaries and deductions which a discovery of such value demands, we will here take the liberty of recalling the principal phases of the study of chyluria con- sidered as a parasitic affection. Our distinguished colleague, Doctor Th Yictorino Pereira, in his inaugural thesis, has very judiciously divided the history of hmmato-chyluria into four periods: — 1st, Period of the unknown origin ; 2nd, Flgyptian period ; 3rd, 1 2 TRANSLATION. Brazilian period ; 4th, Indian period. It is actually necessary to add (5th) the Australian period.* In the first, as says our colleague, the hsematuria was considered as an eliminatory flow of the fat that was not burnt in consequence of a vice of the haematosis ; in the second, as due to the parasite of Bilharz; in the third, as re-asserting itself in consequence of the presence of the filaria of Wucherer; in the fourth, as a symptom of the in- fection of the blood by a new hematozoon, this same Filaria of Wucherer; in the fifth, wc ought to add, it will be re- garded as one of the symptoms of the helminthiasis occasioned by the adult representative of these microscopic embryos. Leaving aside the first epoch of investigation of the hsemato-chyluria (an epoch of hesitation, of conjectures and of theories more or less ingenious, that subsequent facts began to shake and which recent discoveries have deprived of all the interest and all the importance in which they rejoiced), wc shall occupy ourselves with those epochs during which this affection began to be considered under an alto- gether different aspect — thanks to clinical observation and to the revelations of the microscope, which came to replace purely speculative controversies. In 1851 Bilharz discovered the parasite which now bears his name ( Bilharzia hamatobia, Cobbold), and the associa- tion of its presence with the hsemato-chyluria of Egypt ; a fact confirmed by other observers in this same African region, and later by Dr. G. Harley in the urine of a patient who contracted the disease at the Cape of Good Hope. In August, 1806, our regretted collaborator and friend. Dr. Wucherer, occupying himself, at the invitation of the learned Griesinger, to verify here the preceding discovery, as well of this nematodet as of its eggs, found in the chylous urine of one of our patients an embryonic nematoid alto- gether unknown. A few years after, this important fact was also confirmed in the United States by Salisbury, in the Antilles by Crevaux, and in India by Lewis. Here and in these regions the constant presence of this worm in the milky urine became notorious. It seems proper to recall a circumstance very remarkable * To this must also be added a Gtk or Chinese period — relating to the discovery of the larva: and their metamorphoses witnin the stomach of the mosquito ( Culex mosquito). This has been communicated to Dr. Cobbold by Dr. Patrick Manson, who is stationed at Amoy, Chiua. See a letter in The Lancet for January 12th, 1878 (p. 69). — Eds. f In the French Dr. Lima is made to say “ Ce nematode,” but clearly the words ought to be “ ce trematode,” as the author refers to Bilharzia. —Eds. TRANSLATION. 3 by its singularity, which, at a given moment, if this fact remains unique till now, has had a considerable influence on the pathological explanation of the hsemato-chylous urine. At the moment when Wucherer was seeking for the Bilharzia hamatobia he found instead of it an unknown worm * Later on. Dr. Cobbold, studying the embryology of this fluke-parasite in the urine of a patient who had resided in Africa, discovered the eggs of a nematoid which contained embryons perfectly resembling those of Wucherer. In 1872 Dr. Lewis not only verified at Calcutta the pre- sence of these nematoids in the embryonal state in the chylous urine, but, what is more extraordinary, he discovered them equally in the blood of the patients affected with ehyluria, diarrhoea, elephantiasis, and even in persons appearing to be in good health. He proposed for the designation of this new species of non-adult helminth the provisional denomination of Filaria sanguinis hominis. Some time after, 1\ Sousino also dis- covered the same animalcules in the blood of the hacmaturics of Egypt. In 1875 Dr. O’Neill on the West Coast of Africa, and our studious colleague, Dr. Araujo at Bahia, encountered, almost at the same time, the same microscopic Filaria, pro- ceeding from the skin affected with a disease peculiar to uegroes, which they called “ craw-craw,” and to which Filaria our compatriot gives the name of Filar lose dermathe - mica. f llecently a distinguished medical man. Dr. Felicio dos Santos, encountered the same embryonal nematoid in the blood of an individual affected with elephantiasis — a unique fact up to the present time in relation to patients of this kind, and which since has never been verified at Bahia in spite of all tentative efforts made to do so. Such are, in short, the facts relative to the coexistence of animalcules with hasmato-chyluria, and with other affections which do not appear to possess in common the least patho- logical analogy. The Bilharzia associated with ha
