    Some forms of ‘granm lar-lids’; when taken in connection with what is known to occur in connection with the migration of several parasites, are too prominently associated writli the history of the cases in which these Haematozoa were detected to permit of the subject being passed over without comment. With reference to the ‘granular-lid’ condition of one of the patients affected with Haematozoa, it has been demonstrated since the earlier pages of this paper was in type, that, not only had congestion resulted from the presence of the Filariae, but actual rupture and escape of one of them at least occurred, either through the channel of the lachrymal or of a Meibomian gland (see foot-note, page 13). Although feeling convinced that Chyluria and other morbid phenomena are induced by the presence of these microscopic Filariae in the circulation, still, unless it can be shown that they may have a prolonged existence in this con- dition, it will be difficult to reconcile this opinion with the fact that the malady so frequently recurs in the same individual. It seems unlikely that the same per- son should become re-infected with Haematozoa several times, and especially that re-infection should occur after years of residence in England, where probably this par- ticular Filaria is not indigenous. Not having been able to watch the progress of Haematozoa in lower is°latctl CaSCS a Sufficiently long ammais m dogs, &c. period to judge whether or not all the Haematozoa in the system escape during a single attack of Chyluria (the period of their existence in the The recurring at- tacks of Chyluria.
