office promptly, renders much more valuable assistance to the 

 Bureau than even a veterinarian may do who is lax and un- 

 businesslike in his methods. 



The Legislature also amended sections 11 and 27 of chap- 

 ter 90 of the Revised Laws, relative to reports of contagious 

 diseases being made to the Chief of the Cattle Bureau, so 

 as to render the law effective, and has thus remedied the 

 defects to which attention has been called in previous reports. 



Tuberculosis. 



At the International Congress on Tuberculosis, held at 

 Washington during the past autumn, all kinds of views were 

 presented by various scientists upon the danger to mankind 

 from consuming the products of tuberculous cattle, Koch on 

 the one hand saying that in taking measures for preventing 

 the spread of tuberculosis in the human race the cow could 

 be looked upon as a negligible factor, while on the other 

 hand men like Dr. G. Simms Woodhead of the Royal British 

 Commission, and Professor Arloing of Lyons, France, con- 

 sider the use of the uncooked milk and other dairy products 

 from tuberculous cows as very dangerous. The safest views 

 to adopt are those of conservative men, such as Dr. Theobald 

 Smith of Massachusetts, who believes there is a certain 

 amount of danger from the use of raw milk from tuberculous 

 cows, but that the danger has been in many instances exag- 

 gerated. 



Dr. Smith was the first to discover a difference in the 

 tubercle bacilli found in sputum and the type found in cattle. 

 Koch speaks of them as the typus humanus and typus hovinus 

 of the tubercle bacillus. Dr. Smith and his former assistant. 

 Dr. P. A. LcMas, have investigated a number of cases of 

 various kinds of tuberculosis, and in the cervical glands of 

 children have found the typus hovinus in a number of in- 

 stances. They have also been found in mesenteric glands, 

 and may also occasionally be found associated with cases of 

 tuberculous meningitis in children. 



In about 50 per cent of the cases of tuberculosis of the 

 cervical lymph glands studied by Dr. Smith and Dr. Lewis 

 they found the bovine type of the tubercle bacillus present,
