Rare separate issue of Numan's detailed and beautifully illustrated study of the larvae of the equine botfly (family Oestridae), an internal parasite of horses. The author, Alexander Numan (1780-1852) discusses the different species of botfly found in the stomachs of horses, the way the eggs are transferred to the intestines, their growth and development, the effect on the health of the host animal, and the various ways they can be removed. The essay appeared both in the Nieuwe Verhandelingen der eerste klasse van het Koninklijk-Nederlandse Instituut van Wetenschappen, and in the present much rarer separate issue, where only the plates refer to the journal.
Numan is best known for his essays on the Keil dysentery epidemic of 1810 (1812) and on cow pox (1831).
