Animal Pathology . — The late Dr. Bancroft addressed 
himself to several matters regarding' animal diseases. As 
instance of this may be mentioned his investigation of the 
nature of the “Birdsville (Qld.) Horse Disease” in 1892; 
this indicated that it was “an epizootic pneumonia, prob- 
ably of bacterial origin.” In a short paper, “ Notes on 
Some Diseases in, Stock in Queensland” (Rep. Chief Insp. 
Stock, Qld., 1892, p. 4 and Appendix), the following addi- 
tional stock disease are also identified as occurring in 
Queensland : — 
Horses : — Maw Worm, Spiroptera megastoma ; Lung 
Worm, Strongylus micrurus; Worm aneurum, Strongylus 
armatus, of the mesenteric arteries; Intestinal Worms, 
Ascaris megalocephala ; the Worm-parasite, Oxyuris cur - 
rula ; a Tape Worm, probably Taenia plicata ; “ Swamp 
Cancer,” a sarcoma and not a carcinoma; true cancerous 
growth from the eye and conjunctiva of a horse. 
Cattle. — Tuberculosis, pleuro-pneumonia, and actino- 
mycosis of the lower jaw, all in a Diamantina oxen; the 
small harmless stomach fluke, Amp hist oma conicum; the 
nodule-forming work Oesophagostoma cohimbianum of 
intestines, mesentery and Orientum (also in sheep) ; On- 
chocerca Worm Nodules; Ricketts, Zamia poisoning; sym- 
ptomatic Anthrax of calves; so-called '‘Cancer” of aged 
cows, a sarcoma; Scrotal Tumour, Lymphangioma ; gen- 
uine local car cinamot ous growth in dogs. 
To revert to the subject of maladies of the horse, it 
may be noted that in 1891 the late Dr. Bancroft read a 
paper before the Royal Society of Queensland (Proc. R. 
Soc. Qld., Vol. VIII., p. 65-7, 1892), “On Psoraisis in 
Horses, known in Queensland as Mange,” and that had 
been, during 1888 and 1889, the-, object of investigation on 
the part ofl others who had affirmed that it was a disease 
of parasitic origin, caused by the fungus Trichopyton , 
whereas it was one “of a climatic and constitutional 
nature,” pigment having been mistaken for this fungus. 
Considerable attention was also bestowed on the dis- 
eases of rodents in view of the significant role played by 
certain rat species as transmitters of human maladies. 
Thus in 1893 we have his paper, “On, the Whip Worm of 
the Rat's Liver, Trichocephalus sp. ”, read before the Royal 
Society of New South Wales* (Proc. R. Soc. N.S.W., 1893 
p. 86-90, Vol. VII.). 
Medical Entomology . — Dr. T. L. Bancroft being so 
closely associated with his father, Dr. Joseph Bancroft,
