does not communicate with the outer world: the cirrus bores directly into the 

 parenchyma, breaking through the cuticula at places that are not predetermined. 



These 1'acts are thought to be of sufficient weight for the creation of a genus, but 

 this is deferred until the relationships are considered in a later paper. 



On the oesophagus of nematodes, especially of Strongylus armatus and Doch- 

 mius duodenalis, L. A. J^lGERSKIOld (Bihang Svenska Vetensk. Akad. Handl, 

 {,1891), IV, No. 5, pp. 1-26, pis. 2; abs. in Zool. Centbl., 5 (189;), No. 2, p. 48).— The 

 author finds that the glands iu the dorsal side of the oesophagus in Strongylus arma- 

 tus and Ankylostomum duodi nale open into the oral cavity at its anterior end. 



The strongylus of the sheep's stomach, C. Julien, (Jour. Agr. Prat.. 1 i 1 

 No. 4, pp. 137-142, figs. 5).— The affected animals are caused to drink a glass of water 

 with some linseed oil in which there is mixed at the moment of administration 5 to 

 6 cc. of benzin for.lambs or 6 to 8 cc. for sheep. If the animal is very sick the dose 

 should be graduated, beginning with 2 to 3 cc. 



Bothriotasnia chilensis, n. sp., E. Riggenbach (Actes Soe. Sci. Chile, . 1 . >,pp. 

 73, pi. 1; abs. in Zool. Centbl., ■', , 1897), No. 2, p. 47).— This new species was taken 

 from Genypterus chilensis and reaches a length of 5 cm. The scolex bears 2 flask-like 

 independent bothridia. The genital pores lie irregularly anil alternatingly on both 

 sides of the body, the uterus opening on the ventral surface of the proglottid. The 

 body surface is covered with pores of fine and numerous excretory vessels. 



The development of the sporozoa of the genus Coccidium, P. L. Simoxd 

 {Ann. Inst. Pasteur, 11 {1897), No. 6, pp. 546-581, pis. £).— By means of experiments 

 on rabbits and on Salamandra maculata and by microscopical observations the author 

 has found that Coccidium ori forme and C. {Ear yophagus) salamandrce, instead of being 

 dimorphic in their cycle of development, are polymorphic. What applies to this 

 applies with slight modification also to C. proprium and, in all probability, to the 

 rest of the genus.

 (1897), pt. II, pp. 1-51, pis. .?: abs. iu Zool. Centbl., 5 I 189& \, No. :. p. 49).— The new 

 form Oxyuris stossichii from the intestine of Hystrix cristata is described. 



Tuberculosis in cattle (Ontario Dept. Agr., Spec. Bui. 1897, July, pp. 12, pis. :•. — 

 This is a popular bulletin designed to awaken the attention of Canadian cattle breed- 

 ers to the \\ idespread existence of tuberculosis, giving popular directions for testing 

 suspected animals, enumerating the utensils used in making the tests, and stating 

 where the instruments may l>e obtained.

Beet sugar production in Sweden (Tidslcr. Landtman, 18, Xo. '/, 



pp. 06-99). — The total quantity of beets worked during the campaign 

 of 1895-96 was 535,149.4 tons. The products obtained were 54,822.41 

 tons first sugars, 5,371.86 seconds, 1,920.61 thirds i total. 62,114.88 tons), 

 and 15.753.4 tons of molasses. The amount of sugar obtained was 

 11.75 per cent and that of molasses 2.94 per cent of the tonnage of 

 beets. The average content of polarized sugar in the beets was 13.45 

 per cent, the range in the average per cent for all factories being from 

 12.18 to 14.51 per cent. The average sugar content in single factories 

 ranged between 9.3 and 15.8 per cent. 



The factory at Roma, Gotland, which is largely, if not entirely, sup- 

 plied by beets grown on marsh soils, received the richest beets. The 

 average content of sugar in the beets was 15 per cent, the percentage 

 ranging from 14.5 to 15.8. The yield of sugar was 12.75 per cent and 

 that of molasses 3.02 per cent of the tonnage of beets worked.
