JAMES JAGO, B.A. (Cantab.) and M.D. (Oxon.), was a physician of 

 considerable repute in West Cornwall. He was born on De- 

 cember 18, 1815, at the barton of Kigilliack, Budock, near Falmouth. 

 once a seat of the Bishops of Exeter. He was the second son of 

 Mr. John Jago, and the representative of an old Cornish family, who 

 were resident in the parish of St. Erme, near Truro, before the year 

 1588. One of his lineal ancestors was a staunch Parliamentarian, 

 who was appointed a Commissioner of Sequestration by Oliver 

 Cromwell, after the death of Charles I. Young Jago received his 

 early education at the Falmouth Classical and Mathematical School, 

 where he remained a pupil until about 1833. About this time he 

 expressed a strong desire to go through a course of training at one 

 of the Universities, but preparatory to this he had the benefit of 

 some private tuition. He had, however, always a great respect for 

 the instruction he received in the Falmouth School, and he retained 

 a deep interest in its prosperity to the end of his life. 



In 1835 Mr. Jago entered St. John's College, Cambridge, as a 

 pensioner, and graduated B.A. in the Mathematical Tripos of 1839 as 

 32nd Wrangler. Soon after obtaining his degree, he resolved to 

 adopt the medical profession as his future occupation of life. For 

 this purpose, and to obtain the necessary qualifications, he studied at 

 various hospitals in London, Dublin, and- Paris. But anxious to 

 obtain a good medical degree, he resolved to go through a special 

 second course of training at the University of Oxford, where he 

 accordingly entered his name as a student, both in arts and medicine, 

 on the books of Wadham College, from which he graduated B.A. 

 and M.B. in 1843, and finally M.D. in 1859. 



During the early years of his professional career, after he had 

 chosen Truro for his residence, Dr. Jago was a voluminous writer on 

 various medical subjects, the most important of which were investi- 

 gations on certain special diseases of the eye. One of his first con- 

 tributions on this subject, contained in a series of papers published 

 in the 'London Medical Gazette,' is that entitled "Points in the 

 Physiology and Diseases of the Eye." In these papers he developed 

 certain entoptical methods of exploring the eye by means of 

 divergent beams of light, which he considered to be an explanation 

 which preceded all like solutions of the problem. In 1854 he com- 

 municated to the Royal Society a paper on " Ocular Spectres and
