Post Mortem Reports. 
CocKATi-;i:i, : Capt. Ivatligan. — This liird died of enteritis of the haemorrhagic 
tv]H'. U is quite likel\ that the cause lay in the bundle of weeds put into 
the aviary. Several plants of the r.ij^wort f.ainily eontain a ]ioison in 
their leaves fatal In nKiniin.ik .nul hirds. 
Dufrksnk's \\'axt?i i.t. : Capt. Ratti<;an. — Cause of death a ruptured li\er. 
Possilih- pursued li\ anotl'er l)ii-d it dashed a.t;.ains| the wire and ruptured 
its liver. 
(joi.DicN Pi]i-:.\s.\N"r ; Capi. Rattigan. — Cause of ..ealh in this ease bronchitis. 
Possibly it was a bird which, being- hatched at the time when tiie drought 
wa.s at its worst was alwavs weaklv.

Crimson-winof.d P.\kr.\ki-;I':t ; The Marquis of Tavistock. — Cause of death 
enteritis. The association of a lit with this is by no means unusual, 
fn babies intestinal disorders are among the conmionest causes of con- 
vulsions. 
UL.\rK-r.\ii,i:n Pahraki'i'.t : The Marquis of Tavistock. — Cause of death 
enteritis. 
DuKuicsNi'.'s W'axbii.t, ; Mr. S. Yealland. — Cause of death pneumonia. This 
can be such an acute disease that the bird may have every appearance 
of health, even a short time before death. 
Two TA.\A(a;i!s : Capt. f'ieeve. — ISoth these Itirds died of mycosis of lungs 
and air-sacs. This is an infectious disease, but one which robust birds 
seem able to overcome, while weakly, newly imported birds succumb to it. 
The disease is caused by a fungus which spreads by spores. If the aviary 
is now empty disinfect it before placing anything more in it. If it is 
not, disinfection is not much use as the birds now in it may have become 
carriers. In this case do not put in fresh birds unless they are in 
robust health. 
DttNLiN : M. R. Tomlinson. — This bird died of mycosis. It probably had 
the disease all the time, and becoming run down died of it. For further 
details see above. 
Cordon Bleu : Mrs. Calvocoressi. — The cause of death was enteritis. 
Orange-flanked Parr.\keet : Mrs. Sproston. — The cause of death was 
enteritis. 
Thuke Rird.s : [. Weir.- — The birds were all decomposed. I fear analysis 
of bird foods is somewhat too involved a subject to be undertaken at 
present, in view of the lack of knowledge of the normal contents of bird 
foods.
