appears not to be urged by any vicious propensity. At this 

 period, in the cow, the secretion of milk is at an end. 



The above symptoms continue on the increase until the sixth 

 or seventh day. At length the hind extremities become so pa- 

 ralysed as to render standing on the feet impossible ; the con- 

 stant straining at the rectum still forces out faces, and the ani- 

 mal refuses all, or almost all, further sustenance ; even bread 

 that is forced with the hand into the creature's throat, is not 

 swallowed. A dread of water is never observed, even though 

 the latter be refused. Naturally thin and rough haired cattle 

 become still thinner, and their hair rougher ; but such as were 

 originally in good condition and smooth -haired, shew little al- 

 teration in either respect. Some time between the sixth and 

 the ninth day, the animals sink on one side (mostly, I have ob- 

 served, on the left) with the head commonly stretched back- 

 wards ; the eye still remaining bright, lively, and uninflamed. 

 From henceforth the trunk continues motionless, whilst the legs 

 undergo a constant but languid movement to and fro, until the 

 animal has ceased to exist. In the form above described, the 

 animals may be approached with little or no danger. Not so 

 in the second form ; of which, however, scarcely one case is ob- 

 served in six. 



This form commences like the other. In the stable, the ani- 

 mals recede still more from the manger, and will even break 

 the rope with which they are fastened, if it is not very strong. 

 Their bellowing, without being frequent, is prolonged, its tone 

 clear, thrilling, and unmodulated. They scratch the ground 

 with their fore-hoofs, often with such violence, that the dung 

 is projected to the roof of the stable ; whilst with their hind 

 legs they kick violently at any one who approaches. At this 

 stage, the paroxysms are periodical, and little is to be obser- 

 ved during the intervals, except a reluctance to feed or drink. 

 About the fourth day, if they are naturally strong, they will 

 snap every kind of fastening in twain during the paroxysm, 

 and then attack and gore all who approach them. They rage 

 about in the stable, gnawing the ribs and other objects to pieces, 

 until palsy of the joints supervenes, when they sink down, and 

 ultimately fall on one side. In this position they still manage, 

 spasmodically as it were, to shove themselves about the stable
