specific disease, hut due to various causes. It is found impossible to 

 transmit the disease by artificial inoculation. 



In a paper on the clinical study of blood. V. A. .Moore called atten- 

 tion to the importance of such study in the diagnosis of human and 

 animal diseases. The author's work was largely confined to the 

 horse. It was found desirable to take blood samples from the 

 capillaries of the skin to determine the number of red blood cor- 

 puscles. The amount of hemoglobin was then determined. Special 

 attention was given to tin 1 study of normal variations. The red 

 blood corpuscles were found to vary from 7,000,000 to 9,000,000 

 per cubic millimeter, and the total leucocytes from 4,000 to 6,000, 

 while the average number of red blood corpuscles were 7,944,000 

 per cubic millimeter. In suppurative process the polynuclear cells 

 increase, while the eosinophils decrease 1 in numbers. In pneumonia 

 the latter cells completely disappear, while in cachexia the red cor- 

 puscles may become as few as 2,000,000 per cubic millimeter. 

 Surgical operation under chloroform has the effect of greatly increas- 

 ing the number of red corpuscles. A differential count of the blood 

 elements is considered of great assistance in diagnosis. 



F. V. Brown read a paper on Mallein as a Cure for Glanders. Mai 

 lein was used in testing 301 horses which were killed for glanders in 

 Kansas City in 1!><>3. In 149 cases the temperature reached K>2 F. 

 or more, and varied from that to 106° F. Sixty-five of these animals 

 were again tested after 30 days, and in 64 of them the temperature 

 reached 103 : F. or more. From subsequent history of these and other 

 cases the speaker believed that glanders may be cured by the use of 

 mallein. 



In discussing this question, C. H. Higgins stated that 3,147 horses 

 had been tested in Canada, with a reaction in 592 cases. A large per- 

 centage of these horses ceased to react in later tests. In Canada the 

 second test is applied after 4<> days, the third after 100 days, and the 

 fourth after L90 days. J. G. Rutherford, continuing the discussion, 

 urged care in discharging ceased reactors. Some Canadian restric- 

 tions are removed in case of these animals; but horses which react 

 with a temperature of 105° F. at the first test seldom recover. Of 730 

 reacting horses, 181 ceased to react after subsequent tests; but this 

 percentage is not considered sufficient to pay for repeated inspections 

 and tests. It is recommended, therefore, that all reacting horses be 

 killed. In the future the Canadian Government will pay no indem- 

 nity for cases with clinical symptoms, while reactors without clinical 

 symptoms will be paid for at the rate of two-thirds of their value. 



C. C. Lyford discussed the subject of quittors and sidebones. These 

 diseases, in the speaker's opinion, can not be cured with medicaments.- 

 It is recommended that the lateral cartilage be excised. The foot must 

 be previously prepared by softening. Where possible, the division of
