On the nerves which supply the muscular structure of the heart

The author remarks that, in a paper entitled "On the Ganglia and Nerves of the Heart,” published in the Philosophical Transactions, Part I. 1839, it is asserted, that “it can be clearly demonstrated that every artery distributed throughout the walls or the uterus and heart, and every muscular fasciculus of these organs, is supplied with nerves upon which ganglia are formed". He then states that “recent dissections which I have made of the heart of the race-horse, in which both the muscular and nervous structures are largely developed, demonstrate, that from the outer surface to the lining membrane the walls are universally pervaded with nerves, on which ganglia are formed, or enlargements invested with neurilemma, into which nerves enter and from which they issue, as in all the other ganglia of the great sympathetic nerve.
