Parasites as an aid in determining organic relationship, X. A. Cobb (Agr. 

 Gaz. New South Wales, 15 I 1904), No. :>. pp. 845-848).— The presence of parasites may 

 be used in throwing light upon the relationship between their hosts. Parasites 

 may thus serve as an aid in discovering specific and generic relationships in follow- 

 ing metamorphoses and in determining various problems of physiological chemist 

 such as those connected with toxins and antitoxins. 



The cat as a host of Taenia echinococcus, F. Deve | Compt. Rend. Soc. Biol. 

 [Paris], 5? i 1904), No. 28, pp. 262-264). — It was found possible by means of feeding 

 experiments to infest cats with this parasite. Since, therefore, it has been shown 

 that cats may become infested it is of considerable importance to remember this fact 

 in the study of the distribution of contagion with echinococcus. 



The structure of the intestinal epithelial cells of Distomum hepaticum, A. 

 Prenant {Compt. Raul. Soc. Biol. [Paris'], 56 (1904), No. 11, pp. 522-525). — Brief 

 notes are given on the histological details of structure of the epithelial cells of the 

 intestines of liver flukes. 



The common liver fluke in Hawaii, J. ('. Smith and 1). L. Van Qine i Hawaii 

 Sta. Press B\d. 11, pp. 7, figs. 10). — The liver nuke is considered to be very prevalent 

 in Hawaii, especially among cattle. It was found in 990 out of 3,376 cattle slaugh- 

 tered in Honolulu, and in some localities the infestation seems to be even mote 

 extensive. 



The life history of this pest is given together with descriptive notes on the worm 

 in its different stages. In controlling the liver fluke it is recommended that infested 

 cattle be slaughtered before the last stages of the disease develop. No drugs have 

 given much success in treating the disease, although some good may derive from the 

 use of tonics. 



Lime and sulphur dip for maggots in sheep (Jour. Bd. Agr. [London], 11 

 (1904), No. 7, pp. 4®2f 423). — An experiment was made in dipping sheep with a 

 lime-sulphur dip containing 25 lbs. sulphur per Yl\ lbs. lime. A quantity of water 

 was used suttieient to give a dark red color, and before using the liquid was diluted 

 to 100 gal. The dip proved effective for sheep scab and did not materially injure 

 the wool. Brief notes are also given on the prevalence of the maggots in sheep. 



Lime and sulphur dip (Agr. Jour. Cape Good Hope, 25 (1904), X"- 3, pp. 325- 

 .330). — A portion of a debate is presented as it took place in the legislative council of 

 Cape Colony regarding the efficacy of lime and sulphur dip. The majority of the 

 speakers believed that this dip is more effective than any other in the prevention of 

 sheep scab, and it was urged that greater attention be given to preventing the use of 

 imported dips not properly prepared. The bad results which have attended the use 

 of some dips of this class have discouraged sheep raisers and led them to oppose the 

 government sheep scab act. 



Serum treatment in hog cholera, J. Torgersex i Maahedsskr. Dyrla ger, 16 (1904), 

 No. 1, pp. 1-4). — The results obtained from an application of serum treatment in 

 cases of this disease have not always been satisfactory. In the author's experiments 

 5 to 10 cc. of serum ancf 0.3 cc. of vaccine were used. After a few injections the 

 affected animals were noticeably improved. Only 4 per cent of infected animals 

 died after this treatment and none of the healthy vaccinated animals took the 

 disease, although subsequently exposed to infection. 



Swine fever, A. F. Harbek (Natal Ayr. Jour, and Mm. Rec, 7 (1904), No. 8, pj>. 

 737, 738). — Hog cholera has recently appeared in Natal, and on account of the great 

 economic importance of this disease notes an- given on its symptoms, pathological 

 anatomy, and" treatment. 



Experiments in treating cerebro-spinal meningitis (so-called Borna horse 

 disease) with lecithin, H. Raebigek ( D< ■'»(. Tierarztl. Wchnschr., 12 (1904), Nos. 

 39, pp. 385-389; 40, pp. 397-402). — The author presents a general discussion of this
