NOTES AND EXHIBITS. '217 



in the bladder-walls, and from the appearances presented, jyoat- 

 mortem, by the bladder, the conclusion seems to be justified that 

 the disease is due to the effect of some toxin. This view is the 

 more remarkable in that there is no evidence of toxic action 

 elsewhere, even in the kidneys; and in that the bladder, so far as 

 known, is neither an absorptive nor eliminating organ. Amongst 

 the workers in one of the coal-tar dye-industries it is said that 

 growths of a malignant nature in the bladder are not uncommon, 

 which, if the case, would support the toxic theory. It may be 

 that the poison, after rapid elimination by the kidneys, has time 

 to exert a baneful influence while stored in the bladder. A 

 popular view in the South Coast is that the plant Indigofera 

 australis is to blame for the condition. Another plant suggested 

 by Mr. Hamilton is Omalanthus; and Mr. Maiden had been good 

 enough to furnish notes on references to the supposed poisonous 

 effect on cattle of both these plants. Therein it is stated that, 

 in 1894, Mr. Holtze attributed Red-water in the Northern 

 Territory to a species of Omalanthus, The opportunity of con- 

 sulting the original paper is lacking; but it is possible that the 

 cases were really due to Piroplasmosis. Such parasites are 

 absent from the Illawarra cases, however. Experiments are now 

 in progress to test the poisonous action of both the plants in 

 question. In the meantime, information or aid which will help 

 in unravelling the etiology of this interesting and obscure 

 disease will be very acceptable. 



Mr. T. Harvey Johnston, of the Bureau of Microbiology, 

 exhibited specimens of following species of Entozoa from New 

 South Wales (unless otherwise stated). The presence of many 

 of these is now recorded for the first time. A collection from 

 local horses included Anoplocephala inamillana (Mehlis), A. per- 

 foliata (Goeze) and A. plicata (Rud.), Oxyuris curvula Rud., 

 Ascaris megalocephala (Cloq.), Sclerostomuin {Cylichnostomum) 

 teti'acanthum (Mehlis), S. edentaium Looss.(=-S. equinum Mull., 

 in part), Spiroptera microstoma (Schn.) and -.S'. megastoma (Rud.). 

 Echinococcus polymorphiis Dies., was recently taken from the liver 

 of a horse at Berry by Dr. Cleland (also of the Bureau); the only
