“ Experiment with watery extract of Duhoisia upon the 
Normal eye." 
E.C.F.— Age 30. 
(rather better). Acc=| (reads No. 1 Jaeger at 3 inches ) 
Internal rectus overcomes prism of 10° ; external rectus of 5° ; inferior 
rectus of 3°. 
August 30. — Instil two drops of watery extract of Duboisia. In 
ten minutes pupil widely dilated; reads No. 1 Jaeger at 4 inches. In 
fifteen minutes reads No. 1 Jaeger at 5J inches. In 25 minutes No. 
1 Jaeger indistinct at any distance ; reads No. 2 Jaeger not nearer 
than 18 inches. In 30 minutes accommodation completely paralyzed, 
and 1| Sueden is put at 24 inches in the attempt to make it out. In- 
ternal rectus overcomes prism of 10°, external of 4° (this slight 
apparent difference is, I think, doubtful) — inferior of 3°. 
August 31. — Accommodation still completely paralyzed, pupil a 
little less. 
September 1. — Eeads No. 2 Jaeger at 13 inches ; pupil dim- 
inishing. 
September 2. — Eeads No. 1 Jaeger at 6 inches ; pupil diminished 
about 
September 3.— Eeads No. 1 Jaeger at 3| inches ; pupil still less 
and mobile. At this date, four days after instdlation, the effect upon 
the accommodation has practically gone off though a considerable 
mydriasis remained, and some slight dazzling and uncertainty of 
vision for 3 or 4 days longer.

The genus Duboisia, named by Eobert Brown after a French 
botanist, is placed by Bentham, first on the list in the order 
Scrophularinese, p. 475, Flora Australiensis, vol. 4 ; the next 
genus is Anthoeercis, p. 474. Anthocercis littorea is figured in 
Loudon’s Kncyclopsedia, p. 535, the etymology being given. 
4 4 Anthocercis from ai/#os, a flower and Kep/as, a ray ; the narrow 
division of the corolla spreading in a radiant manner, like the 
spokes of a wheel.” It is placed here in Solanese. 
The following description of the plant in question is copied 
from the Flora Australiensis, vol. 4, p. 473-474 : — 
Calyx 5-toothed. Corolla ovate campanulate, the lobes broad, 
induplicate in the bud. Stamens 4, didynamous, included in the tube, 
the upper ones the longest, the fifth uppermost one reduced to a min- 
ute rudiment ; anthers reniform, turned outwards at least when fully 
out, the cells confluent at the apex. Stigma slightly dilated and 2-lobed. 
Fruit an indehiscent berry. Seeds few, curved, with a crustaceous 
tubercular-rugose testa ; embryo curved, the albumen not copious. — 
Small glabrous tree. Leaves alternate, entire. Flowers small, in 
terminal centrifugal panicles.
