fessional knowledge at foreign schools. On his return he became 
associated with his father in practice, and he joined the New Town 
Dispensary as one of its medical officers. The subject of Ausculta- 
tion occupied a considerable share of his attention, and in 1842 he 
published a translation of Barth and Koger’s Practical Treatise on 
that subject. He communicated a paper to the Koyal Society of 
Edinburgh on certain circumstances affecting the colour of blood 
during coagulation. 
Dr Newbigging filled many important situations in Edinburgh, 
such as Surgeon to John Watson’s Institution, and to Cauvin’s Hos- 
pital ; Medical Eeferee of the Life Association Insurance Company 
of Scotland ; Physician to the Sick Children’s Hospital, an institu- 
tion in the foundation of which he took a lively interest ; Examiner 
in the College of Surgeons, and President of that body, 1861-63, as 
well as President of the Eoyal Scottish Society of Arts. He became 
a Fellow of the Eoyal Society in 1848. For several years he suffered 
from valvular disease of the heart and aneurism of the aorta. The 
symptoms were long very obscure, and the existence of the disease 
w^as only known to a very few intimate friends. In spite of it he 
continued to perform efficiently his responsible duties to the last. 
Long before his death he found that any exertion, especially in 
walking up a rising ground, caused breathlessness and exhaustion. 
He did not make this known, and rather endeavoured to conceal it; 
so that few who saw his cheerful and active demeanour could have 
suspected that he was labouring under a fatal disease which was 
gradually undermining his constitution. The autumn before his 
death he resided for some time at Callander, where, by quiet and 
relaxation, he hoped to recruit his strength. On his return to Edin- 
burgh, however, in October, the symptoms became aggravated, 
although he was able to visit his patients till within three days of 
his death, which took place on the morning of Saturday 10th 
January 18-64. Those who knew him intimately perceived a soft- 
ening influence coming over him, and an occasional solemnity of 
expression which betokened Christian preparation for a life beyond 
the present. He was a sound, judicious, and successful practitioner, 
and was much beloved by his patients. He exhibited on all occa- 
sions a courteous, cheerful, and gentlemanly demeanour, and his 
amiability gained him many friends.
