without much difficulty, by which any one may obtain it rea¬ 
dily for his observations. 
Reaumur, having pursued the Sheep-bot through its changes, 
obtained from his own coach-horses the Larvae of the Haemor- 
rhoidal or Fundament Bot, and bred the Fly from it. He was 
successful also in raising to the Fly state, another and more 
rare species, the Oe. Veterinus, or Red Bot-jfty ; but, like Val- 
lisneri, he was in doubt and perplexity whether they were 
varieties or the saiue species. His figures are better than 
Vallisneri’s, which were hardly cognizable or characteristic 
enough to identify the species ; being taken, perhaps, from mu¬ 
tilated specimens, or drawn without sufficient care, or from 
the difficulty of finding artists at this period. But what is 
most singular is, that neither of these celebrated naturalists 
appear to have known our common large Horse-bot, (Oe. Equi,) 
which made these writers much more difficult properly to 
understand ; or if they knew it, they have at least not figured 
or described it. 
In a subsequent volume, Tom. V. of this ingenious writer, 
(.Memoires sur les Insectes,) he has given us an account of the 
Bot of the Stag, at least the Grub or Larva, for the Chrysalis 
or Fly he appears not to have known. He found these Larvas 
in a sort of capsule or sac of the Fauces near the root of the 
tongue, and it is probable we may possess in our cabinets the 
perfect Insect of this Larva, which chance or accident may have 
thrown in our way, without knowing what it is, as it has never 
yet been bred through its different states, in order with cer¬ 
tainty to identify it. Whether the Fauces or the large opening 
of the Eustachian Trumpet into the Fauces of these animals, is 
their proper habitation, we know not, or whether they crawled 
thither after death, from the sinuses of the face or any other 
parts, is uncertain. I have remarked, however, that those
