consequently, the amount of green surface was somewhat 
small, plainly showing the large amount of arsenic employed 
in making the colour. 
The application of Reinsch’s process showed the presence 
of arsenic in both the green contents of the stomach and the 
paper found in the heap of rubbish. 
The heart, lungs, and all the other organs were quite 
healthy. 
A peculiarity of this case is the short time the animal 
lived after partaking of the poison, which in all probability 
was not more than a few hours, and this is rendered more 
interesting from the small quantity taken. 
Cases are recorded in the Veterinarian (June and July, 
1865), in which the animals lived twelve hours, and others 
recovered, profuse diarrhoea being a leading symptom. In 
my case, the time the animal lived did not allow of this 
taking place.

The Narcissales, which have next to be considered, form 
on the whole a most natural alliance, related to the Stratiotes, 
or water soldier, by the simple tripetaloideous flowers of the 
Bromeliacece and Taccads , and gaining a higher pitch of 
beauty in form, colour, and variety in the Amaryllids and 
Irids , in which latter, especially, the flowers are hexapeta- 
loideous, by reason of two sets of petals arranged in threes, 
the nature of which arrangement may be studied by examin- 
ing any of the forms of iris of the garden, or the common 
wild yellow iris, I. Pseud-acorus of our rivers and ponds. 
The Narcissales, Narcissal Alliance, consist of epigynous 
petaloid endogens, with symmetrical flowers, three or six 
stamens, and albuminous seeds. 
The Natural Orders of Narcissales. 
Bromeliacea . — Flowers tripetaloideous, six leaved, imbricated. 
Taccacea . — Flowers half tripetaloideous, tubular. 
llamodoracetp . — Flowers hexapetaloideous, tubular, scarcely imbricated. 
Hypoxidacea . — Flowers hexapetaloideous, much imbricated, stamens six, 
anthers turned outwards. 
Amaryllidaceoe . — Flowers hexapetaloideous, much imbricated, stamens six 
or more, anthers turned inwards. 
Iridacea . — Flowers hexapetaloideous, stamens three, opposite the petals.
