interesting reaction was noted when .sulphuric acid was run 

 under the coverglass of a water preparation containing these 

 ova for the purpose of separating the lid, the interior of the 

 eggs invariably assuming a pink to red color, very like the 

 well-known "cholera red reaction" with stools of Asiatic 

 cholera and doubtless due to the same cause, the presence 

 of indol. The absolute identification of the material is, of 

 course, not to be insisted upon, but the writer believes the 

 specimens to be a variety or in ..very close relation toDibothrio- 

 cephalus latus. The host was an American fox, but it is 

 not known from what part of the country it originally came. 



27. Bothridium pythonis, Blainville ( Solenophorus 

 mcgalocephalus, Creplin), has been obtained several times 

 (Path. Mus., 40; Path. Hist., 774) from pythons; once from 

 the intestine of a Python molurus, at autopsy, in the Zoo- 

 logical Gardens, and again in the dejecta of a living Python 

 reticulatus in the collection of the Gardens. Numerous 

 examples were found in the material from each snake (cf. 

 article on Solenophorus megalocephalus by Smith and Veeder, 

 Trans. Phila. Path. Soc., 1905). Recently another lot of 

 these same worms have been sent to the laboratory from the 

 Gardens, having been discharged together with a large 

 number of ascarides from a Python reticulatus, but as yet 

 these have not been fully studied and recorded, and are not 

 included in the present series. 



III. Nematodes. 



28. Ascaris lumbricoides, \A\rn., horn the human intestine, 

 has been submitted to the laboratory a number of times 

 (among others, Path. Mus., 38; Path. Hist., 1179), most 

 of which have unfortunately not been recorded. Among 

 those not placed of record was one vomited by a child in the 

 early part of an attack of measles, and in the same family 

 several days earlier another child with the same infectious 

 disease passed several of the worms via recti. The voidance
