believed that the orjj;anisiu luids entranee through the iui«il pat-sages'. Experiments 

 conducted hy the authors for tlie purpose of attenuating the organism were partly 

 successful. Cultures of the organism maintained for 1 hour at a temperature of 60 

 or 70° C. failed to protluce any immunity to the disease' when inoculated for pre- 

 ventive purposes. 



White scour and lung disease of calves in Ireland, E. Noc.vkd {Rec. Med. Vet. 

 Paris. S. xer., S {I'JOl), Xo. 10, pp. JS 1-244). — Detailed notes are given on the symp- 

 toms and pathological lesions of this disease. A bacteriological study indicated 

 clearly that white scour is due to an umbilical infection, which maybe prevented by 

 cleansing the cows with a solution of lysol before parturition. It is recommended 

 that the umbilical cord be washed with a mixture containing 1 liter of water, 2 gm. 

 of metallic iodin, and 4 gm. of potassium iodid; and later with a solution of 2 gm. of 

 metallic iodin in 1 liter of methyl alcohol. 



Contribution to the study of jaundice, or heemoglobinuria of cattle in 

 Tunis, E. DrcLOUx {Bal. Dir. Agr. el Cum., 6 {1901), Xo. 20, pp. 244-^7).— The 

 author investigated the disease which is known in Tunis under various names and 

 which prevails to a considerable extent. A preliminary study of the subject showed 

 a striking resemblance of the disease to Texas fever. A further study confirmed this 

 idea, and the blood parasite of Texas fever w^as found in affected animals. 



Enzootic abortion, J. Steele {Vet. Jour., 52 {1901), Xo.Sll, pp. 27 5-27 8).— The 

 symjitoms and nature of this disease are discussed in detail and the usual antiseptic 

 precautions are recommended. 



The injurious effects of certain grass seeds on live stock, J. D. Stewart 

 {Agr. Gaz. Xeir South Wales, 12 {1901), Xo. 3, pp. 357-360, pi. i).— Attention is called 

 to tie injurious effects of certain grass seeds which bear sharp awns. The grasses 

 mentioned as being most injurious are barley grass and "spear grass." The injuri- 

 ous effects of these awns on horses are more severe than on cattle, but even in the 

 latter animals swellings are produced upon the jaw from the irritation set up by the 

 presence of these awns in the flesh. Such swellings have in some instances been 

 mistaken for tuberculosis or actinomycosis. 



The action of acid salts of morphin on ruminants, Hess {Arch. Tr/ss. u. 

 Pral-t. Thierh., 27 {1901), Xo. 3-4, pp. 233-268) .—The author discusses the literature 

 of the subject in connection with an extensive bibliography. The results obtained 

 by different experimenters are very contradictory, but the desirability is recognized 

 of finding a more convenient method of narcosis for ruminants than by ether or 

 chloroform. It was found during the numerous experiments of the author that none 

 of the ruminants or hogs were immune to the action of morphin and that the stimu- 

 lating effect of normal doses was especially noticeable. When large doses were given 

 serious paralytic effects were observed, as is the case in man, and a complete narcosis 

 was not produced without administering doses which were likely to prove fatal. 



Rumenotomy, Xuesch {SrJnmz. Arch. Tliierh., 43 {1001), Xo. 2, pp. 60-62, fig. 1).— 

 A description is given of an instrument designed for making an incision into the first 

 stomach in case of tympanites. The instrument has a sharp point upon a short 

 blade of moderate width and is circular in cross section behind the blade. The 

 circular part of the instrument carries a groove on one side, which extends into the 

 handle and ])ermits the gas to escape. 



The teeth of cattle and sheep as affected by age, C. McCulloch ( Virginia 

 Sta. Bill. 118, pp. 145-155, fgx. 8). — Brief descriptive notes on the anatomical char- 

 acteristics of the teeth of cattle and sheep, with a short account of the changes which 

 they undergo. 



The teeth of the horse as affected by age, C. ^IcCuli.ocit {Virginia Sta. Bal. 

 117, )>j). 129-144, A'A"*- -'•'^)- — Virk'i notes on the changes which take place in the teeth 

 of the horse between the ages of 6 and 21 years.
