ON THE INTRODUCTION OF AIR 
The following students of the Edinburgh Veterinary School 
received their diplomas on the 20th of April, after ^•public exa¬ 
mination lasting during two days. It was conducted by Sir Geo. 
Ballingall ; Professors Graham and Lizars, and Drs. Borthwick, 
Knox, Bobertson, Aitken, and Handyside; Mr. Ferguson, Sur¬ 
geon, and Messrs. Black and Robertson, Veterinary Surgeons 
of the 14th Light Dragoons and 9th Lancers. The two latter 
gentlemen took a very kind and active part in the examination. 
So nearly balanced were the merits of the candidates for the 
prizes, that it was only after a re-examination of two of the can¬ 
didates that the judges were able to make their award. 
Mr. Edward Dycer, Dublin. 
— John Barker, Dumfries. 
— D. Murray, Methven. 
— Andrew McGregor, Crieff. 
— Lewis Brockhurst, Hastings. 
— James Robertson, London. ^ 
— James Ritchie, Perthshire. 
— William Paton, Inchinnan. 
— James M^Dougall, West Kilpatrick. 
— John Currie, Rowland, near Galashiels. 
— John Cockburn, Haddington. 
— Archd. A. Wilson, Edinburgh. 
The prize for the best examination was adjudged to Mr. Ed¬ 
ward Dycer, of Dublin; and Mr. Dick, in consequence of the 
equality that appeared between that student and Mr. John Bar¬ 
ker, of Dumfries, gave an additional prize to Mr. Barker. The 
first prize for the best anatomical preparation was also given 
to Mr. Dycer, and the second to Mr. David Murray, Methven, 
Perthshire. 
ON THE INTRODUCTION OF AIR INTO THE VEINS 
OF LIVING ANIMALS. 
[Continued from p. 252.] 
We now proceed to the question of the introduction of air into 
the vascular system ,* 1st, In relation to the mechanism of that 
introduction when it takes place spontaneouslyy as it was some¬ 
what erroneously stated in a former part of the essay; 2dly, In 
relation to the changes in the vascular system which are found 
after death; 3dly, With reference to the various accidents, and 
even loss of life, which may result from the presence of air in this 
system; 4thly, The probable remedial measures; and, 5thly, 
The inferences which may be deduced from these experiments on
