DESCRIPTION OF PLATES. 



Plate XIII. 

 Fig. 1. Photo-micrograph of a section from a lesion produced 

 under artificial conditions by larvae of Habronema megastoma. A 

 typical necrotic area is seen with a worm canal in the centre con- 

 taining a degenerating larva. Tumour removed nine days after 

 inoculation. 



Fig. 2. Photo-micrograph of another portion of the section 

 used for Fig. 1. The formation of multinucleated cells is well 

 illustrated. 



Fig. 3. Photo-micrograph of another portion of the section 

 used for Fig. 1. A degenerating larva with no surrounding 

 necrosis of the tissues is illustrated. 



Plate XIV. 



Fig. 4. Photo-micrograph of another portion of the section 

 used for Fig. 1. A small necrotic area is seen, and close to it a 

 degenerating larva with only slight necrosis of the surrounding 

 cells . 



Fig. 5. Photo-micrograph of a section from a lesion pro- 

 duced under artificial conditions by larvae of Habronema 

 microstoma. A necrotic area is seen with a degenerating larva 

 at its lower edge. Tumour removed ten days after inoculation. 



Fig. 6. — Photo-micrograph of a section removed six hours 

 after inoculation with larvae of Habronema microstoma. Larvae- 

 are seen surrounded by leucocytes. 



Plate XV. 



Fig. 7. Photo-micrograph of a transverse section of the bulb 

 of the proboscis of Stomoxys calcitrans showing the situation of 

 the larvae. 



Fig. 8. "Swamp cancer" in the Solomon Islands. Lesions 

 on both fore-legs of the animal are well shown.
