344 THE DISEASES AND DISORDERS OF THE OX. 



derful value of sea-air that we would most urgently insist upon. 

 Eecently Dr. Albert Gresswell attended a little boy of eight 

 years of age who had a rather sharp attack of scarlet fever. He 

 progressed very favourably under his care, without any untoward 

 symptoms arising. So soon as he was quite strong enough to 

 be moved, and able to stand the change, he was, in accordance 

 with instructions, sent to the seaside, every precaution being 

 taken against any chance of catching cold, and so forth. The 

 beneficial results which followed were very gratifying, and it was 

 not long before he was quite restored to health and vigour. 

 This is one case out of very many, and Dr. Gresswell speaks 

 strongly in favour of residence at the seaside in the convalescent 

 stages of scarlet fever. 



Having given a short general account of scarlet- fever, 

 we now proceed to consider the recently made discoveries in 

 relation to the etiology of scarlet fever, the far-reaching im- 

 portance of which cannot well be over-estimated. In the first 

 place, then, we may say that concurrent outbreaks of scarlet 

 fever were observed in the months of November and December 

 1885 in Marylebone, St. Pancras, Hampstead, St. John's Wood, 

 and Hendon, among persons who had received their milk from 

 a dairy situated at Hendon. An investigation was accordingly 

 made by Mr. Power, with the result that the suspected dairy 

 was found to be in a good hygienic condition. Moreover, it 

 was elicited that no scarlet fever was prevalent, or had occurred 

 for a long time in the neighbourhood of the dairy. Further- 

 more, the fever had broken out soon after the introduction into 

 the dairy-farm of three newly purchased cows, and one of these 

 cows was found to have small vesicles and ulcers on the udder 

 and teats. This affection did not interfere with the yield of 

 milk, and though it was not attended with any marked obvious 

 signs of illness, it nevertheless spread rapidly among the cows 

 which occupied certain sheds whence the suspected milk was 

 derived. Moreover, some milk which had been condemned and 

 was to have been thrown away was given to certain poor persons 

 living near, and the result was that a severe outbreak of scarlet 

 fever occurred among their children after a week had elapsed, 

 and, we believe, especially among such persons as had derived 

 their milk from the shed wherein the affected cows were kept. 

 Two of the affected cows were then purchased and handed
