Larvse which infest the Horse’s stomach never let go their hold, 
or move after the death of the animal, but are always found 
fixed to the coats of the stomach, that this apprehension of 
their moving after death is perhaps without real foundation. 
To obtain certain information of this species, and procure 
the Fly, would not be an unpleasing task, or difficult to exe¬ 
cute, by one having leisure and the opportunity of a paik ot 
deer for his observations. It would be only necessary for this 
purpose to keep a few of these animals for the two or three 
summer months, or through the months of June or July only, 
in a confined place, having a smooth iloor, or one boarded or 
bricked, on which, by frequent search, the Larva fully grown, 
and falling from the nose or mouth, or perhaps the anus, would 
be easily discovered, and its advancement afterwards to the 
perfect or winged state would be attended with little or no 
trouble or difficulty. The Larva of this species, as figured by 
Reaumur, has considerable affinity to that of the Sheep, but 
is larger, and somewhat differently coloured. See Tom. V. 
p. 67, PI. 9, fig- 2, 6. I mention this the more particularly to 
draw the attention of others to it. 
The next who has given us any account of these Insects worth 
noticing is Baron De Geer, an Envoy or Ambassador, we 
believe him to have been, from the French Court to the Court 
of Sweeden. He was eminently skilled in the natural history 
of Insects, and was the intimate friend of Linneus. Fie de¬ 
scribed the true Ox-bot, and the large Horse-hot, and was aware 
of the Linnean error in respect to these two Insects, which it 
is singular Linneus did not avail himself of, but, like an origi¬ 
nal writer, he perhaps perused but little those that followed him. 
De Geer, however, not having perhaps ever seen the Ha’.mor- 
rhoidulis, confounded it with the Ox-bot, from the similarity 
of its description. His figures are but indifferent, and very 
inferior to those of Reaumur ; nor has he much more than
