altered tissues, Professor Penbertliy wrote me : — " I should call the 



material inflammatory product in the subcutaneous tissues 



Inflammatory product is made up of constituents of blood exuded 

 through vessel-walls which have been damaged. It is allowed, too, by 

 some pathologists that inflammation, too, may excite growth of the 

 cells previously existing in the part. The dark red colouring is most 

 probably due to escape of blood from small vessels which have ruptured ; 

 the orange-coloured material which I have found in some cases is 

 inflammatory product undergoing degenerative changes, in others 

 decomposing warbles." — J. P. 



A few days later Mr. Child further wrote that the sample which he 

 sent me of inflamed tissue was obtained from the animal while in the 

 process of dressing, so that the inflamed matter was taken both from 

 the hide and the carcase at the same time. 



" In watching the slaughterman take off the hide, we were sur- 

 prised to find the warble-grub present, a somewhat rare case so late 

 in July ; however, it enabled me to send you a perfect sample on a 

 small scale. But during the worst part of the warble-season they 

 sometimes cover one-third and in some few cases one-half of the entire 

 carcase ; the warble always develops on the top of the animal from the 

 shoulder to the tail-head, which spoils the choicest parts of the carcase, 

 ruins the best parts of the hide, and makes it worthless when tanned 

 for many purposes, namely, for harness, engine-straps, boot-soles, &c. 

 The effect on the carcase of the animal afflicted with warbles in regard 

 to colour is, when quite dry after dressing, in some cases a pale 

 yellow, in others a light brown, and in some scarce examples dark as 

 mahogany." — J. C. 



On the 17th of May a very good specimen was sent me, by favour 

 of Mr. Henry Thompson, from Workington, in Cumberland. This 

 was a large piece, containing the back-bone, flesh, and hide, all cut 

 right out of the centre of the animal after slaughtering. This was 

 an excellent specimen for our purpose, because it was so moderately 

 warbled that it showed how mischief may arise, even from an average 

 or less than average amount of warble-presence. 



Eegarding this specimen. Prof. Penberthy (who kindly examined it 

 for me) wrote me from the Eoyal Veterinary College on May 20th : — 

 *' The parcel arrived quite safely, and the contents in good preserva- 

 tion." ... "In a superficies of 450 inches I found eighteen well- 

 developed and eight very small warbles. There was, however, ample 

 evidence of inflammatory products. 



" The change had not apparently affected the red flesh (muscles). 

 It so happens that in the parts more seriously invaded the muscles are 

 covered with dense fibrous tissue. 



" This morning, in those parts in which the warbles were most
