Jean-Henri Magne

Jean-Henri Magne (15 July 1804, Sauveterre-de-Rouergue – 27 August 1885) was a French veterinarian.

Portrait by Louis Georges Neumann

During his career, he worked as a professor at the École royale vétérinaire de Lyon and at the École nationale vétérinaire d'Alfort, where from 1846, he served as director.[1]

In 1836 he became a member of the Société linnéenne de Lyon, serving as its president in 1841/42. He was also a member of the Académie d'agriculture de France and the Académie vétérinaire de France, being chosen as its president in 1855.[1]

Published works

From 1848 to 1853, he was director of the agricultural journal, Le Moniteur agricole.[2] With mycologist Claude Casimir Gillet, he collaborated on Nouvelle flore française (1873), a botanical work that was issued over several editions. He was the author of the following writings:

  • Principes d'agriculture et d'hygiène vétérinaire, 1843 – Principles of agriculture and veterinary health.
  • Choix des vaches laitières, 1850 – Selection of dairy cows.
  • Rapport sur les progrès de la médecine vétérinaire depuis vingt-cinq ans, 1867 – Report on the progress of veterinary medicine for the past twenty-five years.
  • Hygiène vétérinaire appliquée (third edition in 1867) – Applied veterinary health.[3]
gollark: By multiplying two smallish prime numbers (inaccessible to the user except via the debug API, if it was available in potatOS (it's not, fully)) to make a bigger *semi*prime it's possible to make a problem easy to generate but relatively hard to solve.
gollark: It's actually very fast.
gollark: ```lualocal function isprime(n) for i = 2, math.sqrt(n) do if n % i == 0 then return false end end return trueend local function findprime(from) local i = from while true do if isprime(i) then return i end i = i + 1 endend```
gollark: ```lua if settings.get "potatOS.removable" then potatOS.actually_really_uninstall = function(hedgehog) if hedgehog == "76fde5717a89e332513d4f1e5b36f6cb" then print "Hedgehog valid. Deleting potatOS main code." fs.delete "/autorun" else error "Invalid hedgehog! Expected 76fde5717a89e332513d4f1e5b36f6cb." end end end```Also this bit, optionally.
gollark: ```lua begin_uninstall_process = function() print "Please wait. Generating semiprime number..." local p1 = findprime(math.random(2, 100000)) local p2 = findprime(math.random(2, 100000)) local num = p1 * p2 print("Please find the prime factors of the following number:", num) write "Factor 1: " local f1 = tonumber(read()) write "Factor 2: " local f2 = tonumber(read()) if (f1 == p1 and f2 == p2) or (f2 == p1 and f1 == p2) then term.clear() term.setCursorPos(1, 1) print "Accepted. Moving startup." fs.delete "old-potatOS-startup" fs.move("startup", "old-potatOS-startup") print "Press any key to continue." os.pullEvent "key" os.reboot() else print("Factors", f1, f2, "invalid.", p1, p2, "expected.") end end```This bit is the uninstaller.
