CONTENTS OF REPORT.
PART I.-HISTORY OF THE DISEASE (pp. 1-10).
Para. 1.—Introduction. My movements; work done and methods. (Clinical observation; thermometric
researches; experimental research ; post-mortem investigations ; microscopical examina-
tions ; digests of previous reports, &c; section-cutting little required ; staining; attempts
at cure).
„ 2.—History :—Dr. Evans' discovery of Surra; its possible occurrence during Persian War; also in
Afghan Campaigns ; also in Assam and Australia ; perhaps in Egypt in 1882. Some
obscure cases previously observed by me probably " Surra."
„ 3.—1883 outbreak in Rangoon. Illustrative chart.
„ 4 & 5.—1884 outbreak in Rangoon and Tonghoo. No cases reported from Thayetmyo and Moul-
mein. Money-value of mules lost in two years, about Rupees 30,000 ; perhaps the unusual
fatality in elephants also due to it.
„ 6.—Seriously reduces fitness of British Burma transport for field service. Similar disease pre-
vailed in animals also in first Anglo-Burmese War. This perhaps is the disease which used
to prevail at Thayetmyo, necessitating removal of field battery from there. Not known to
prevail among ghari and private horses in Rangoon. I have evidence of at least one case.
Was the disease brought from the Punjab ? Almost certainly not.
„ 7.—Veterinary Surgeon Frost reports on the disease. Inspecting Veterinary Surgeon Evans'
opinion. Inspecting Veterinary Surgeon Shaw deputed to inquire into the matter. Disease
absent on his arrival. His views as to its nature, and suggestions. I am deputed to
investigate the outbreak.
„ 8.—PRECIS OF KNOWLEDGE OF THE DISES BEFORE MY ARRIVAL. Symptoms observed at Rangoon
and Tonghoo.
„ 9.—Post-mortem appearances as noted before my arrival ; also opinions as to pathology. Ulceration
of stomach. Doubt as to its true nature. Observations of Veterinary Surgeon (First-class)
Frost, Inspecting Veterinary Surgeon Shaw, and Dr. Romanis.
„ 10.—Reports of Medical Officers at Tonghoo. Theory of irritant poisoning.
„ 11.—Etiology.—The water suspected, especially that from certain tanks. Chemical analysis.
Microscopical observations. Inspecting Veterinary Surgeon Shaw's views.
„ 12 to 14.—Influence of exposure, locality, and age as causes.
„ 15.—Evidence of Officer Commanding Left Half Battalion, 2nd Bedfordshire Regiment. Loss
of large-sized mules especially, associated with performance of puckal duty.
„ 16.—Treatment: preventative and curative.—Negative results only obtained.
„ 17.—Rough outline of my researches.
PART II.—THE OUTBREAKS (pp. 10—37).
Para. 1.—Enzootic not recognized as such. Variety of supposed causes of death at Tonghoo.
Inspecting Veterinary Surgeon Evans visits Tonghoo and examines the cases, makes
post-mortem examinations and microscopical investigations of the blood, and is left in
doubt. This difficulty met. The disease at Tonghoo true Relapsing Fever as seen at
Rangoon.
„ 2.—Veterinary Surgeon Frost shows ulceration of stomach. Is this due to malicious poisoning ?
Arguments pro and con. Argument about it being due to water from special tanks.
Inspecting Veterinary Surgeon Shaw's experiment not satisfactorily carried out. Conclu-
sion that we cannot blame any special source of water-supply.
„ 3.—Relations which ulceration of the stomach bears to relapsing fever in this outbreak.
Discussion of the theory of the disease being simple gastric ulceration. Its feasibility.
Conclusion that it is not the disease. Statistics of prevalence of gastric ulceration in the
cases. Pathological condition of the stomach.
„ 4.—Notes by Dr. Evans, Tonghoo Medical Officers, and myself. Nature of yellow coloration
of stomach. Microscopical examination of stomach lesions. The ulceration is a
secondary lesion due to general disease. Is it caused or determined by defects in
feeding ? It occurs in experimental cases. All the symptoms of gastric ulceration are not
necessarily in Relapsing Fever found post-mortem in association with ulceration.
„ 5.—My first theory of it being gastric typhoid. Basis of this. Clear ovidences of it being a
disease of the blood. Not simple starvation or anæmia due to imperfect feeding ! Why
the active organisms were not detected in previous blood examinations. Detection of the
organisms.
„ 6.—Clinical records and charts of ordinary and experimental cases, some simple, some compli
cated. Dr. Evans' opinion on the relations of Surra and the British Burma disease.
Comparison of symptoms in the two disorders. Also post-mortem results and the condition
of the parasites. The diseases probably both varieties of " Relapsing Fever of Equines."
„ 7.—Differences between Tonghoo and Rangoon disease. Always doubt in diagnosis at
Tonghoo.
