CATTLE COMMISSIONERS' REPORT. 193 



disease prevails in low-lying districts, on land near rivers, 

 more especially after heavy floods, and is mostly seen in the 

 months of August, September, and October, and in calves 

 less than one year old, but very rarely in those rising two 

 years old." The seat of the irritation is indicated by a 

 bronchial cough. There is a loss of flesh, a varying degree 

 of constitutional disturbance, and death by suffocation, if the 

 animal is not relieved. By an examination of the mucus 

 which the sufferer coughs up, the parasites may be discov- 

 ered. Bronchial irritation occurring in calves during the 

 summer or autumn should be looked upon with suspicion, 

 and its source thoroughly inquired into. If the calves 

 should die, a careful post-mortem examination ought to be 

 made in order that the pathological condition of the lungs 

 can be determined. If death does not ensue, the mucous dis- 

 charge from the nose should be examined, when, in all proba- 

 bility, some of the parasites will be found. The infected 

 animals should be removed from contact with the healthy, 

 not because the disease is contagious in itself, but because 

 the parasites, or the ova discharged by them, are liable to 

 gain access into their bodies, where they multiply, and the 

 trouble is extended. The healthy animals should be placed 

 in high, dry pastures, and not allowed to graze on land 

 wliich has been occupied by the sick ; for the parasites live a 

 long time, though the probable period is not determined. In 

 treating the disease, the animals should be warmly housed if 

 •the nights are cold ; and inhalations of chlorine or sulphurous 

 acid are recommended. If it is carefully done, the sufferers 

 may be kept surrounded with an atmosphere saturated with 

 either of these acids for fifteen minutes each day, until tlie 

 trouble disappears ; but two or three inhalations are gener- 

 ally sufficient. 



If inhalation is objected to, turpentine may be adminis- 

 tered in gruel daily, or, what has often been found efficacious, 

 from ten to twenty minims doses of Schule's hydrocj^anic 

 acid with carbonate of soda ; and some bitter stomachic, as 

 gentian or chamomile, ma}^ be given twice a day. The ani- 

 mals affected with this disease, of wliich mention has been 

 made, came from St. Lawrence County, New York: they 

 were in the Brighton j^ards but two days ; and, as no cattle 

 within our jurisdiction have developed the disease, it is to be
