extremity of the tail for inflicting a wound, nor was there m the 
mouth any aculeus ; that their effects upon the Rhem-deer m so 
driving them did not admit of explanation. He describes the 
abdomen as having a telescopic tube at its extremity, which is 
probably similar to the one already given with the CE. Bovis, ant 
is peculiar to the female, as in other Flies. On observing the 
tumors in the back a few weeks afterwards, that had been touche 
by the insect, he found an opening that would admit a goose quill; 
he squeezed these tumors with his fingers, which the animal cou c 
but badly endure, but he persisted in pressing them till he made 
the larva come out through the opening, which he describes as 
being white, of an oval figure, extremely tender and delicate, the 
extremity black, which presented to the opening. The body with 
circular folds and curved lines. 
One of these flies he describes as following the rhem-deer that 
carried his clothes, and was always near or upon the animal ; she 
had her tail held out, and carried rather to one side and curved 
upwards, and upon its extremity a white egg, as large as a cymps, 
or hemp seed perhaps. I had (he says) an opportunity the whole 
day of seeing this insect continually following him, and sometimes 
going before him ; and so careful was it about depositing its egg, 
that it did not care to place it upon the rein-deer if it did not 
stand tolerably still, but dropped it on one side; and so persevering 
was it to follow him, that at last it became exhausted and fainted 
away, and fell down on the snow mountain with fatigue, so that it 
could be taken with the hands, but shortly after, when it had been 
a minute on the snow and recovered itself, it flew to the next green 
spot, where it rested, and then again pursued the rhein-deer. 
It was curious to observe the striving of the dogs, the boys, 
and the rhein, which would run many times round the hut of the 
Laplander, before it would proceed to the pasture where it was 
to feed, if with the wind, but against the wind the rein wou 
proceed with alacrity, for by his flight when proceeding m this
