pectoralis transversus and other muscles were found to harbour a 

 considerable number of encysted Trichinae. 



Exp. 10. On the 20th March, and again on the 21st (1865), 

 " feedings " from the same human subject were administered to a 

 hedgehog. On the 26th of April the animal seemed to be attacked 

 with symptoms of trichinosis. It refused food, kept its head ex- 

 tended and the eyelids closed. On the 27th it appeared much 

 worse, and on the morning of the 28th it was found dead. On 

 the 29th I examined the flesh and found abundance of living 

 Trichinae in the muscles. The capsules were very thin and trans- 

 parent. A few days later Mr. Simonds also examined the flesh, 

 and confirmed this result. 



Exps. 11 and 12. Two chickens were fed, on the 21st of March, 

 with the same material. One of the birds died on the 24th, when 

 I examined the intestines and detected one or two very minute 

 nematodes, which, at the time, I believed to be imperfectly de- 

 veloped Trichinae, but subsequently saw reason to alter my opinion. 

 The other bird died on the 3rd of April, and certainly contained 

 no muscle-trichinae. 



Exp. 13. On the 22nd and 23rd of March " feedings " amount- 

 ing to an ounce of flesh in all were given to a mole. This animal 

 was returned to the care of Mr. Charles Land, who had previously 

 sent it to the Veterinary College. He subsequently reported that, 

 after observing the mole to be " working " for two or three days, 

 he lost all trace of it, and concluded that it had either escaped or 

 was dead. 



Exp. 14. On the 1st and 2nd of May portions of the left fore 

 extremity of the hedgehog (in which we had successfully reared 

 Trichina from the Middlesex-Hospital subject) were ofiiered by 

 Mr. Simonds to a cat. The "tabby" ate the flesh very readily, 

 consuming the entire limb. On the 15th of the following June 

 the cat was kiUed, when living Trichinae were found within all the 

 muscles which we examined. 



Exp. 15. At the same dates a young terrier dog was similarly 

 treated, but did not take the " feeding " so readily. In this case 

 the left hind extremity of the hedgehog was employed, and what 

 was not eaten voluntarily was forcibly introduced. On the 1st of 

 June the dog was attacked with " distemper," and died on the 8th 

 of the same month. On examination we found several living 

 Trichinae in the sterno-maxillaris and other muscles. Some of the 

 parasites were encysted. 



Exp. 16. Erom the 9th to the 12th of June, inclusive, four sepa-
