attacks alike both man and animal, and apparently no epidermis 

 is strong enough to resist this desire. 



Only one egg is laid at a time, I think, because I have seen 

 many instances where the body has been punctured in several 

 places, and only one worm produced in each. 



The fly appeals to be mainly confined to forest land, and 

 those living on the borders are the chief sufferers. At certain 

 seasons, June and October, the fly is hardest at Avork, and all 

 parts of the human or other body exposed is made an abode for 

 the egg. Wild animals are severely attacked, especially the 

 agouti. The amount of suffering this little rodent goes through 

 while the eggs are incubating must be enormous, for I have shot 

 them when they have been simply a mass of sores caused by the 

 worms forming, and thixs rendered quite unfit for food. Lapp 

 suffer in a similar way, but hardly so severely ; deer in a lesser 

 degree on account of their heavier and closer-haired skins. In 

 one case I extracted four worms from the head of a young un- 

 fledged bird, known as grieve. Domestic animals are often 

 suffei'ers. 



How or when the egg is deposited has perhaps never been 

 ascertained. The worm is brought forth in the manner of an 

 abscess forming, and the pain of such is increased by the con- 

 tinued movement of the Avorm. This movement causes the spot 

 to inflame, and the skin to become thin, and easily broken for 

 the insect's departure for fields afresh and pastures new. I think 

 it has never been found into what state the worm passes on 

 leaving its birthplace*; this is what ought to be followed up. I 

 have tried to breed the worm, and trace its after life, but failure 

 attended my experiments. I suggest here that a way of ob- 

 taining this object would be to place the worm in fresh pork, 

 the meat to be kept at about the temperature of the human 

 body. From this could be watched the after stages of existence 

 the Avorm takes. 



The Avorm at its full groAvth is often three-quarters of an 

 inch long, Avith a small brown head, round serrated body, ending 

 Avith a sharp point of Avhite colour. When a Avorm is discovered 

 the best treatment appears to poultice the place to increase the 

 heat, and so hasten the entrance of the AVorm into its next stage. 

 Iodine injected Avill kill the Avorm, but as the foreign matter 

 remains under the skin, bad after effects may ensue, Avbich may 

 prove Avorse than the cure. 



In hunting, I have often been shoAvn a large black mosquito 

 Avhich the hunters asserted Avas the parent of the Avorm. I call 



* Like other species of parasitical flies it is probable that the worm 

 leaves its unwilling host to go into the earth and turn into a chrysalis. — P.C
