A REMARKABLE GROWTH. 479 



mot %YiLli a case Lhat in any way oqnals llie extraor- 

 dinary tumor to whicli atlcnlion is here ii)viled. Tlie only 

 tliing thal I recall resembling it, is the casc of a Parrot 

 shown in figure 64 of The Diseases of Poultry by Dr. D.- 

 E. Salmon (puhlished at Washington, July 1899), in 

 chaptor xi trcaling of Tiihorciilosis (p. 213). From whal 

 \ve read liiere il is scen tliaL birds sufl'er from a form of 

 tuberculosis peculiarly Iheir own, and quite differenl 

 from mammalian form of the infection. As a rnle ihis 

 latter is not easily transmitted to mammals, the reverse 

 of this being the case in the Psittacidaß^ and Dr. Salmon 

 remarks : « A very interesting fact is that Parrots are 

 usually afTected with the mammalian form of tuber- 

 culosis. The disease is quite .freqiiently seen in Ihese 

 birds and it shows a great tendency to develop externally. 

 It most commonly atTects the borders of the eyes and 

 mouth, the skin and joints of the feet. There are at lirst 

 small swellings, some of which soften, discharge their 

 Contents and become ulcers; others remain hard and 

 continue to enlarge, white still others are covered by a 

 horny grovvtli of considerable thickness. » As the tu- 

 mour in this Curlew was covered by a horny growth, 

 and moreover sprang from the neighborhood of tlie exter- 

 nal nares, there is a bare possibility that it may have 

 been of a tuberculous nature. But to attempt to decide 

 such a question as'this it would have been necessary for 

 me to have made a microscopical examination of the 

 Contents of the enlargement, and this I did not have the 

 opportunity to do.
