History of Influenza, 5 3 



that any living remembered, made its appearance 

 in Dublin, which seems to have been nearly 

 analogous to the influenza and catarrhal fever 

 which seized mankind in the years 1737 and 

 1743, but now particularly attacked the horses 

 in their turn, as may appear by a comparison of 

 their respective histories. It had appeared in 

 England in November and spread through all 

 England almost in an instant, and toward the 

 end of the month began to abate. It raged in 

 Denmark at the same time, but did not reach 

 our horses in Dublin till its decline in England 

 at the time before mentioned. It affected the 

 horses in Munster and Ulster almost if not quite 

 as soon as in Dublin, and there was scarce an 

 instance of a horse in the town or country but 

 what had it. It seized the horses like a violent 

 cold with heaviness, loss of appetite, cough, and 

 laborious breathing, and then a profuse running 

 at the nose and mouth of a digested or thick 

 yellow-greenish matter, upon which they became 

 better in England as well as here.'' In the epi- 

 zootic of 1750 post-mortem appearances similar 

 to those described in 1873 in the epizootic then 

 raging, purpura hemorrhagica^ were noted by an 

 author named Osmore in ^'A Treatise on the 

 Diseases and Lameness of Horses" (London, 

 1766). His words are, '^On many of these I 

 have made several incisions ; I found in all of 

 them a quantity of extravasated serum lodged 

 between the skin and the membranes." In the 

 year 1758 the influenza was both epidemic and 

 epizootic in Great Britain. Dr. Eobert Wyatt,
