EFFUSION INTO THE CAVITY OF THE CHEST. 527 
mixed with several ash-coloured ulcers. He had also an eruption 
of pustules over his body. Some of these were flattened and 
somewhat vesicular, like chicken-pock — some were conical and 
pustular, and some in a state of incrustation. Around several of 
them, particularly those which were in the earlier stage, the 
peculiar white areola was still visible. Several of the joints were 
swelled and painful, and there was evident effusion into the left 
elbow joint. The child was extremely feverish and irritable, 
tossing about in the bed, and raving. The smell from his body 
was extremely offensive. He continued in this way with little 
change in the symptoms until the JLtjth, when he expired. 
All that could be learned of his previous history was, that his 
father was a labourer and kept a horse, which was said to be 
labouring under a discharge from his nostrils, the result of cold ; 
but Dr. Hutton said that he had not as yet seen the animal. 
On examination after death there was an effusion of pus dis- 
covered in the left knee-joint. In the thorax there was a small 
collection of pus close to the edge of the left lung. The lung was 
of a deep red colour, and presented several ecchymosed spots on 
its surface, and contained two small abscesses. The right lung 
presented a few flattened tubercles. These were pointed out to 
the attention of the meeting by Dr. Hutton. 
EFFUSION INTO THE CAVITY OF THE CHEST, 
CAUSED BY THE ACCCIDENTAL INTRODUCTION 
OF A STOCKING NEEDLE. 
By Mr. R. Read, F.6., Crediton. 
A cow, belonging to Mr. Thomas Leach, of Marchweek Farm, 
near Witheridge, was observed, about six weeks since, to be un- 
thrifty, moping, standing about with her back roached, and mak- 
ing an occasional grunting noise. She ate, drank, and ruminated. 
A cough or hoose was never observed prior to or during the con- 
tinuance of her illness; but the coat was arid and stark, and she 
handled badly. Medical assistance was procured, and she was 
treated for a case of dyspepsia; but the cow did not improve. 
About a week since, Mr. Leach requested his brother, Mr. Peter 
Leach, who served his apprenticeship with me and has since con- 
tinued as an assistant, to look at her. On minutely examining 
the cow by immediate auscultation, he imagined that he could 
distinguish the sound of a fluid in the pleural cavity, and hinted 
his opinion to his brother that, from the symptoms that were pie- 
sent, the animal would soon die ; at the same time expressing a
