verminous anapliylaxy. As the lesions of the nervous system are mucli more 

 marked and frequent in the anaphylaxy by worms than in the direct intoxica 

 tion by the parasitar toxins, it seems probable that the nervous phenomena, 

 sometimes very severe, as for instance the symptoms of meuingism, sometimes 

 observed in certain hplminth carriers, must be considered as being of anaphy- 

 lactic nature." 



Physiolog'ical investig'ations of the fixation and mode of nutrition of 

 some nematode parasites of the alimentary canal, C. Gabin (Ann. Univ. 

 Lyon, n. ser., I, No. 34 (1913), pp. 160, figs. 55). — The parts of this comparative 

 study of the manner in which intestinal nematodes gain their nutrition deal 

 with the technique and methods of work, and a study of the fixation and the 

 mode of nutrition of nematodes of the genera Ascaris and Heterakis, Oxyurus 

 vermicttlaris, Strongylus strigosus and S. retortceformis, the genera Trichuris 

 and Spiroptera, G-nathostomum hispidum, etc. 



The studies indicate that the intestinal nematodes find nourishment in the 

 intestinal mucosa of the host and not from the contents of the alimentaiy 

 canal. The majority of the nematodes are attached to the wall of the alimen- 

 tary canal either temporarily or in a definitive manner. The nutrition imbibed 

 by the intestinal nematodes from the walls of the alimentary canal of the 

 host differs with the species but may consist of lymph, epithelial cells, erythro- 

 cytes, and pus cells. 



A bibliography of five pages is appended. 



Aerobic niicro-org'anisms in the omasum and colon of bovines, A. W. 

 BuEMANN (CentU. Bakt. [etc.], 1. AU., Orig., 71 (1913), No. 4, pp. 291-319).— 

 Following a somewhat extensive review of the literature relating to the subject 

 the author reports original investigations and includes descriptions of a num- 

 ber of new species of bacilli. A bibliography of 77 titles is appended. 



The treatment of tick bite in stock (Agr. Gaz. N. S. Wales, 25 (1914), No. 7, 

 p. 569). — It is stated that a tick, identified as Ixodes holocyclus, is vei-y trouble- 

 some in New South Yv'ales in late autumn and early spring, proving fatal to 

 calves, dogs, and pigs, and very painful to cows and hor.ses. It is recommended 

 that a laxative be administered as soon as symptoms of paraly.sis appear, and 

 followed by a tonic. 



Spraying for control of ticks in Antigua, P. T. Saundees (West Indian 

 Bill., 14 (1914), ^0. 2, pp. 122-125, pi. 1). — ^A brief account of work carried on 

 in Antigua. 



Some results of blood counting on cattle, A. B. Clawson (Amer. Vet. Rev., 

 45 (1914), No. 5, pp. 527-536). — This is a report of studies carried on in connec- 

 tion with work conducted by the Oflice of Poisonous Plant Investigations of 

 this Department at Limon (altitude 5,360 ft.) and at Mount Carbon (altitude 

 9,000 ft.), in Colorado. The results are summarized as follows: 



In the older animals there was an average of 7,504,400 red coi-puscles as 

 compared with 9,159,222 in the younger. The animals when taken from an 

 altitude of 5,360 ft. to an altitude of 9,000 ft. showed an increase in the 

 number of red corpu.scles from 8,749,388 to 9,255,878. The counts at the lower 

 elevation, however, were made in early summer, while those at the higher 

 altitude were made largely in midsummer, and had the counts at the two 

 altitudes been made at more nearly the same time the difference might have 

 been greater. The counts at Mount Carbon showed a larger number of retl 

 corpuscles in early than in middle or late summer. 



Is there a bacillary hog cholera? W. Pfeilee (Mitt. Ver. Deut. Schweine-
