“… [I] have extended my observations to the genesis of those entozoan that prove destructive to horses , to beasts of burden generally, and to other creatures which, like cats and dogs , are in various ways subservient to man’s wants.” “I should like to see a small army of helminthologists rise up and lay siege to the fortresses at present securely held by thousands of death- dealing parasites.” 1879, T.

“Veterinary parasitology is a borderline field in which zoology and veterinary medicine meet.” Maurice C. Hall December 30, 1927 American Society of Parasitologists meeting 1928, North American Veterinarian 9 (4): 50-56
“… it is regrettable that the work in parasitology in the Bureau of Animal Industry was not put in the Pathological Division of that Bureau at the start and kept there.” Theobald Smith oral comment, date unknown
Theobald Smith as a Parasitologist Maurice C. Hall 1935, Journal of Parasitology 21 (4): 231-243
“To his [ Theobald Smith’s] mind, parasitology was just a subdivision of pathology.” Maurice C. Hall, 1935 1935 , Journal of Parasitology 21 (4): 231-243
“Clinical parasitology is one of the branches of clinical pathology.” Edward A. Benbrook & Margaret W. Sloss 1948, In introduction to Veterinary Clinical Parasitology

Presidential Address by Maurice C. Hall American Society of Parasitologists 1932 Is Parasitology a Science? 1933, Journal of Parasitology 19 (3): 182-191
“In the immense field of science, parasitology has its place. It has certain tasks which other sciences do not undertake.” Maurice C. Hall, 1932 (published, 1933) 1933, Journal of Parasitology 19 (3): 182-191
The College Course in Veterinary Parasitology Maurice C. Hall 1922, Veterinary Medicine 17 (2): 83-85
“Since the establishment of the comparatively new science of bacteriology, the engaging study of bacteria and of diseases caused by them has dominated the attention of the veterinarians more or less to the exclusion of the study of animal parasites.” Maurice C. Hall, 1922 1922, Veterinary Medicine 17 (2): 83-85
“It will probably be conceded by most American veterinarians that there is no topic in veterinary medicine concerning which the veterinarian is less informed than the subject of parasitology. ” Maurice C. Hall, 1922 1922, Veterinary Medicine 17 (2): 83-85
“The animal parasites are not so spectacular. They take their largest toll among young animals, and the loss is readily explained by the stockman to his own satisfaction on other grounds.” Maurice C. Hall, 1922 1922, Veterinary Medicine 17 (2): 83-85
“When [an animal] finally succumbs to the long siege by the parasites … no explanation of the death appears necessary. The animal ‘never did well’ and the loss is discounted …” Maurice C. Hall, 1922 1922, Veterinary Medicine 17 (2): 83-85
“We are beginning to understand the situation better and to realize what animal parasites do … what parasitism costs in terms of diminished meat and milk production, poorer quality of meat, decreased horse power, increased susceptibility to bacterial and constitutional diseases, and premature deaths.” Maurice C. Hall, 1922 1922, Veterinary Medicine 17 (2): 83-85
Teaching Veterinary Parasitology Maurice C. Hall 1928, North American Veterinarian 9 (3): 41-44
“Another reason for the neglect of veterinary parasitology and of its teaching is the rise of the science of bacteriology about half a century ago, and the subsequent eclipse of parasitology.” Maurice C. Hall, 1927 (published, 1928) 1928, North American Veterinarian 9 (3): 41-44
“… [another reason for] neglect…that is so annoying to the veterinary parasitologist [is] that the parasitic diseases are so insidious and devoid of spectacular characters as a rule.” Maurice C. Hall, 1927 (published, 1928) 1928, North American Veterinarian 9 (3): 41-44
“… veterinary parasitology has been so neglected in the schools … [that] the teaching of parasitology has fallen for the most part to someone who was anything except a parasitologist .” Maurice C. Hall, 1927 (published, 1928) 1928, North American Veterinarian 9 (3): 41-44
“If we are to raise up parasitologists among our veterinary students, we must have the inspiration of teachers of parasitology who are enthusiastic parasitologists .” Maurice C. Hall, 1922 1922, Veterinary Medicine 17 (2): 83-85
“… [teaching parasitology] usually devolved to a pathologist but might fall to almost anyone with an uncrowded teaching schedule.” Maurice C. Hall, 1927 (published, 1928) 1928, North American Veterinarian 9 (3): 41-44
“There is a lack of [veterinary parasitology] text books in English which are accurate, up to date, and reasonably complete …” Maurice C. Hall, 1927 1928, North American Veterinarian 9 (3): 41-44
“… there is a lack of an adequate laboratory manual in veterinary parasitology.” Maurice C. Hall, 1927 (published, 1928) 1928, Veterinary Medicine 9 (3): 41-44
“The life history of a few representative forms … should be experimentally demonstrated.” Maurice C. Hall, 1927 (published, 1928) 1928, North American Veterinarian 9 (3): 41-44
“… before long the veterinary colleges should be able to supply the federal and state services and the colleges of veterinary medicine with well trained and competent veterinary parasitologists .” Maurice C. Hall, 1927 (published, 1928) 1928, North American Veterinarian 9 (3): 41-44
The Economic Importance of Veterinary Parasitology Maurice C. Hall 1928, North American Veterinarian 9 (4): 50-56
“To conclude: Veterinary Parasitology is a subject of growing importance …” Maurice C. Hall December 30, 1927 (published, 1928) 1928, North American Veterinarian 9 (4): 50-56
