After 36 to 48 hours the eyelid beciniies swollen, eileiiiatous, and slightly tense, 

 and the eye ain>eiU's sunken. The tissues lose their supjileness, the skin is 

 rigid and sometimes reddish and moderately sensitive. There may be slight 

 lachrymation. Even a moderate reaction is rendered quite obvious by com- 

 parison with tlio opposite eye. 



" When the ])alpebral and caudal tests are carried out simultaneously they 

 agree exactly, and should one of the tests have heen improperly carried out the 

 other gives a positive result. An important practical point is that tlie tests are 

 complementary, or they correct each otlier. For those wlio lind-tlie intradermic 

 paljjebral test too delicate a manipulation, a sulx-utaneous injection of J to 

 i cc. or more, of tul)erculin may be made into the upi)er or lower eyelid, this 

 yielding a local reaction as characteristic as the intraderm.il test. The author 

 li;is carried out tests upon about (>0 animals, using different doses of tuberculin, 

 and he has found that as good I'esults can be obtained witli i cc. as with 4 cc. 

 If, however, the larger dose be used, the test approximates to the subcutaneous 

 method in th:it it is likely to produce a temperature reaction with the accom- 

 panying disadvantages. The method of testing is held to be free from all the 

 objections that have been raised above against tlie subcutaneous method." 



The author's practice is to make an injection into both eyelids.

Brisket disease (dropsy of high altitudes), G. H. Glover and I. E. Nkwsom 

 (C'llonitlo Sta. Hid. 20.'f (1915). pp. 2'/. figs. 5). — This is a preliminary repoi't 

 of studies of a disease which occurs in cattle at high altitudes in Colorado, the 

 princi])al syni])tonis of which are swelling of the brisket and the loose tissues 

 under the jaw. usually diarrhea, and a moist cough, with gradual emaciation 

 and death. The disease which is chronic in character is fatal in practically all 

 cases. On autoi)sy the most marked symptoms are general dropsy, enlarged and 

 hard liver, and dilated heart. 



Reports are presented of 31 ca.ses un<ler observation. Six cases which were 

 shipped to a lower altitude fabrtut TkOOO ft.) all recovered without other treat- 

 ment, although it is believed that they would have died had they not been 

 shipped. 



" It appears to be caused by an exhaustion of the heart muscle associateil 

 with a varying degree of dilatation and hypertrophy and this being brought 

 about by exertion before acclimatization at high altitudes, or in the case of 

 calves, inherited cardiac weakness. Medical treatment has so far proved of 

 little avail, but where possible shipi)ing the affected animals to a lower altitude 

 is recommended. Preventive measures include the use of hulls that have been 

 raised at altitudes of S.OOO ft. or more, with a view to building u]) ;i hardier 

 strain of cattle, also the furtailment of indiscriminate shipping of low altitude 

 cattle to high altitudes." 



[A disease of cattle reported in Guam which resembles Texas fever], .1. B. 

 Thompson (Guam Sta. R, .. 191^, pp. 22-23. figs. 3). — This is a report of fur- 

 ther studies (E. S. R.. 31. p. 482) of a disease of cattle reported in Guam. 



It is stated that all the imported cattle have again been subject to attacks of 

 fever at various times during the year. Several affected animals succumbed to 

 the disease. Tlie iirincipal symptoms observed in a cow which succumbed 

 March 8 were extreme emaciation, a dejtraved appetite, and a more or less inter-
