One of the more charming aspects of the works of James Herriot is the language and terms. Being fresh out of veterinary collage with a mind full of the new scientific terms it took him a while to cone to terms with the the archaic local jargon that described the ailments of the animals he worked on. Terms such as Stagnation O'T' Lung, Husk, and Runnin on Three Cylinders.
Even in the present day I find that there are many maladies of the horse that linger with their old common names. There are Scratches, Mud Fever AKA Greasy Heel, String Hault, Joint Ill, Aural Plaque, Grass Sickness, Heaves, Moon Blindness,Proud Flesh, Rain Rot, Wobbler, Tying-Up,Ring Bone and Side Bone, Rug Sores, Scours, Navel Ill, Strangles, Founder and my personal favorite, Got A Rib Out.
Many of the common names easily describe the conditions they represent and they still work quite well today. They are much easier to say than their Latin medical terms. It's what keeps modern animal husbandry linked to its colorful past.
