v1 Obituary Notices of Fellows deceased. 
a lucid exposition of his views on the mechanism of speech and thought, and 
the problems of aphasia, a subject in which his interest was maintained 
throughout his life. To this his papers on “A Case of Amnesia,’ on 
“A Particular Form of Amnesia,” “Loss of Nouns,” read before the Royal 
Medical and Chirurgical Society in 1878 and 1884 respectively, and an 
article in the ‘British Medical Journal’ as late as June 15 this year, on 
“Some Affections of Speech,’ bear witness. Indeed, at the time of his 
death he was engaged in writing a treatise on “ Aphasia.” Amongst other 
publications dealing with diseases of the nervous system, were “ Remarks 
on the Pathology of Chorea,” published in the ‘ British Medical Journal’ in 
1869, the Lettsomian Lecture on “Syphilitic Affections of the Nervous 
System,” delivered before the Medical Society of London in 1874, and papers 
on “Ingravescent Apoplexy” and on “ Alcoholic Spinal Paralysis,” read 
before the Royal Medical and Chirurgical Society in 1874 and 1884. In 
1866, the year in which he published his “ Hypothesis,” he contributed an 
article on “ Prognosis in Heart Disease” to the ‘ British Medical Journal.’ 
In 1884, before the Harveian Society of London, he gave the Harveian 
Lectures on “ Prognosis in Valvular Disease of the Heart.” In 1887, at the 
Royal College of Physicians, he delivered the Croonian Lectures on the 
“ Pulse,” and in 1891 the Lumleian Lectures on “Structural Diseases of the 
Heart from the Point of View of Prognosis.” These lectures constituted the 
foundation of a work on “Heart Disease,” published in 1896, in the 
preparation of which he was assisted by his son, Dr. John Broadbent, and of 
which a revised and enlarged edition appeared in 1906. 
His early interest in the scientific application of therapeutics was shown 
by a paper entitled, “An Attempt to Apply Chemical Principles in Explana- 
tion of the Action of Remedies and Poisons,” published in 1869 ; and the 
line of thought in this was followed out in later years in an address on 
“The Remote Effects of Remedies,’ read at the annual meeting of the British 
Medical Association in 1886, and in his Presidential Address delivered before 
the Clinical Society on “The Relation of Pathology and Therapeutics to 
Clinical Medicine.” Amongst other notable contributions to the literature 
on therapeutics is the Cavendish Lecture on “Some Points in the Treatment 
of Typhoid Fever,” which he delivered before the West London Medico- 
Chirurgical Society in 1894. 
Sir Thomas Barlow has observed that, in a remarkable paper submitted 
several years ago to the Royal Medical and Chirurgical Society, but not 
published in its ‘Transactions, Broadbent anticipated the development of 
pharmacology on the lines of chemical affinities of the elements. 
Broadbent has left a record of splendid work done in the advancement 
of neurology. The value of what he did towards the elucidation of different 
problems presented by cases of aphasia is universally acknowledged. This 
is not the place to give details of any of his researches. I shall limit my 
remarks to the wide bearings of a great principle he established, to what is 
known as “ Broadbent’s hypothesis.” This principle has brought method into
