A report on the 1874 plague in Benghazi

pesteI recently came across a small, old pamphlet entitled, in French, “Essai sur la peste de Benghazi en 1874” (Essay on the 1874 plague of Benghazi) written by a certain Dr. Léonard Arnaud (a “médécin sanitaire au service Ottomane”) and published by the Ottoman Health Administration in Constantinople in 1875.

The report deals with an interesting and practically unknown episode of eastern Libyan history: an outbreak of the plague in ‘Benghazi’—then used to indicate the eastern part of modern-day Libya in general—which followed an earlier outbreak in the same region in 1858. This particular outbreak occurred in the encampments of several groups of nomadic Bedouin in the plateaus between Benghazi and al-Merj. Of concern to the Ottoman officials, no doubt, was that Dr. Arnaud identified the disease as the same as the plague which had been occurring in the Levant (according to a report made in London, the Ottoman health service was apparently dealing with a number of plague outbreaks in their Middle Eastern provinces). A quick search for the author reveals that he seems to have been a specialist in dealing with the plague and other epidemics in various territories of the Ottoman empire.

Are there any other sources for this episode of history, Ottoman, Arabic, or European?
