results, those proceeding from altered states of the nutritive processes are then entered upon-and hypertrophy of the brain, and occurrence of morbid growths in the encephalon are treated of in relation to symptoms, pathology and treatment.

The functional diseases of the encephalon, not traceable distinctly to altered distributions of the blood or altered states of nutrition, fall next to be treated of, in relation to symptoms, pathology and treatment.

The functional diseases of the encephalon, not traceable distinctly to altered distributions of the blood, or altered states of nutrition, fall next to be treated of, and in passing to this series it is convenient to consider the disease called delirium tremens.

Its division into 2 species, and the second species into 3 stages is explained.

The symptoms, pathology and treatment of the disease are severally discussed.

Lecture XLIV.

Some forms of functional disease of the brain are now considered and first those forms of headache, cephalalgia not depending on inflammation, or organic disease of the brain are treated of.

The general principles of their pathology and treatment are explained.

The subject of Insanity receives a short and passing notice.

The diseases of the spinal cord, are then commenced with a short notice of those anatomical and physiological facts, relating to the spinal cord, which it is important to bear in mind.

Spinal meningitis and myelitis, inflammation of the membranes and substance of the cord, are separately considered in relation to symptoms and pathology, but conjointly in relation to causes and treatment.

Lecture XLVII.

Having completed the inflammatory diseases of the spinal cord, hæmorrhage and dropsy of the spinal cord are noticed under the names spinal apoplexy, hydro-rachis, and spina bifida.

Spinal irritation as a functional derangement of the spinal cord, is then treated of.

Tetanus, in its several forms in relation to symptoms, pathology, causes, and treatment is then considered; and the lecture concludes with a short notice of hydrophobia, chiefly of the pathology of the disease. Its full consideration forms part of the course of Surgery.

Lecture XLVIII.

There are still functional derangements which not being, as far as can be determined, exclusively confined to the encephalon or to the spinal cord, it is appropriate to consider under the head of functional derangements of the Nervous System.

Of these epilepsy is first considered in relation to its symptoms, pathology, causes and treatment.

From epilepsy, the transition is natural to infantile convulsions, and this subject is treated with some fulness in relation to all important points.

Puerperal convulsions in their full consideration form part of the course of midwifery, but the close relation of much of their pathology, and of the principles of treatment to infantile convulsions is here explained.

Lecture XLIX.

In concluding the functional diseases of the nervous system, Hysteria is next considered. Its varied symptoms, its relation to a particular diathesis, the nature of the causes, the indications to be observed in its treatment, are all explained rather with reference to general principles than by the statement of copious details.

Tetanus, epilepsy, infantile and puerperal convulsions and hysteria, have been instances of the excess of the motor influence of the nervous system. We now come to consider functional diseases of the nervous system, in which motor influence is defective perverted or suspended, and under this head chorea is treated of in relation to symptoms, pathology, causes and treatment.

Lecture L.

Paralysis agitans, mercurial tremors and lead palsy are shortly noticed as further instances of defect of motor influence.

Then, suspension more or less complete of motor influence is next considered as exemplified in the different forms of paralysis. Hemiplegia, paraplegia and local paralysis, depending on congestion or inflammatory derangement of the brain or spinal cord are again. adverted to.

Functional paralysis in relation to infancy and old age, and consecutive on epilepsy, hysteria and chorea, is then treated of.

Neuralgia and anesthesia are then discussed, and are viewed as having the same relation to the sensory afferent portion of the nervous system, as convulsion and paralysis have to the efferent portion. The first involving excess of influence, the second defect or suspension.

As related to the subject of anesthesia, amaurosis is shortly considered.

As time will not admit of much illustration of these important subjects, the attempt is made in this lecture to make these deranged states of the nervous system intelligible, by dwelling on those principles of their pathology, causes and treatment which are common to several; and also by keeping constantly in view, the physiology of the nervous system as now generally received.

Lecture LI.

Having completed the diseases of the nervous systems those of the organs of sense fall next to be considered.

The diseases of the eye will be noticed in the course of surgery.

Of diseases of the ear, otitis, external, internal, acute, chronic is shortly noticed.

Epistaxis is the only disease of the nose which is explained.

The diseases of the tongue were noticed in connection with those of the mouth.

The diseases of the skin are then entered upon. But it is impracticable, within the limits of the course, to enter into the details of this extensive subject. It is therefore merely viewed in relation to certain general principles.

1. It is stated that the diseases of the skin are chiefly inflammations.

2. That much of the classification is grounded on the character, extent, situation, and, above all, the result of the inflammationwhence has arisen the division into 7 orders viz, Exanthemata, Papulce, Squamæ, Vesiculo, Bullo, Pustulo, Tubercula; and these into many species.

3. That states of the constitution from plethora, cachexia, age, the presence of a materies morbi in the blood, the derangement of organic functions, &c., of the stomach, the bowels, the kidneys, have much to do with the pathology of skin diseases.

They are inflammations, secondary on one or other of these deranged conditions.

4. Amongst causes, external irritants, heat, inattention to cleanliness, contagion, are instanced.

5. The general indications to be kept in view in the treatment, both general and local are explained. The eruptive fevers, the syphilitic eruptions are reserved for after consideration.

Lecture LII.

The diseases of the three first divisions, of the course having been considered, those of Division IV, viz., those dependent on an altered state of the blood, are now entered upon.

The first disease treated of in this division is rheumatism in its acute and chronic forms, its fibrous, synovial and muscular varieties. These are all explained in relation to symptoms, pathology, causes and treatment.

Gout is the next subject of consideration, the symptoms are described, its division into regular, irregular and retro-cedent gout is stated; and the pathology, the causes, and the treatment of the disease are discussed.

Lecture LIII.

Scurvy, Scorbutus forms the next subject of consideration. The spmptoms are described, the pathology and causes explained, and the preventive and curative measures set forth, and the notice of the disease concludes with a short account of its history.

Purpura hæmorrhagica, is then treated of, in relation to symptoms, pathology and treatment.

Lecture LIV.

Beriberi is next treated of, and it is classed in the present division, because it is looked upon as a general dropsy excited, by external cold, in individuals predisposed, in consequence of a developing scorbutic diathesis.

2. Tubercular lepra, leprosy, is next considered, its symptoms and diagnostic marks are explained, and the pathology and causes so far as they are understood are stated; and notice is taken of the history of the disease, its former prevalence in European countries, &c. Elephantiasis is then discribed and discussed, with reference to symptoms, pathology, causes and treatment.

That it is a disease altogether different from tubercular lepra or leprosy is particularly explained.

Lecture LV.

1. The general subject of cachexia is discussed, and reference is made to cachexia from deficient food, impure air, malaria, also to the scrofulous, scorbutic, syphilitic, leprous, carcinomatous and mercurial cachexias.

Those phenomena, which are more or less common to all, are pointed out; then the chief circumstances in which they differ from each other are explained,

The general principles to be observed, in the prevention and cure of these cachexias, are stated; and the question of the treatment of syphilis with, or without mercury is considered.

Lecture LVI.

The diseases of Division V of the course-those supposed to proceed from endemic, contagious and epidemic causes are now entered upon.

Intermittent Fever is first considered. The symptoms, the different forms of the disease, and their varieties are described.

The quotidian, tertian and quartan types, and as varieties of these, double and duplicated tertian, double and duplicated quartan, simple and complicated intermittent fever, are alluded to.

The pathology, causes and treatment of intermittent fever, are treated of in some detail.

Lecture LVII.

In continuation of diseases depending on endemic causes, remittent fever is next considered, and the following forms are severally noticed simple, inflammatory, bilious, and congestive remittent fever-typhoid or adynamic, and malignant remittent, also remittent fever complicated with internal inflammations, and with jaundice.

The various forms of remittent fever are considered in relation to symptoms, and pathology, and in the general notice of the treatment, with which the lecture concludes, reference is made to the modifications required in the most important of these forms.

Lecture LVIII.

It is convenient, though not in the strict order of the arrangement of the course, to consider, before proceeding to notice the diseases depending on infectious causes, certain forms of idiopathic fever, produced by one or more of the ordinary exciting causes of disease. Ephemeral fever,-The continued inflammatory or ardent fever of tropical countries, are viewed as of this nature-and are here explained in relation to symptoms, pathology, and treatment.

The diseases depending upon infectious causes, are now entered upon, and the continued fever of the colder climates, in its forms of synocha, synochus and typhus, is treated of in relation to symptoms, pathology, causes, and treatment. But as the discase is unknown in tropical countries, it is not discussed in much detail.

It is now enquired whether the intermittent, remittent, and continued forms of fever exhibit modifications, when they occur in the early periods of life; and in the course of the enquiry the nature of Infantile remittent fever is explained.
