TETANUS IN A HEIFER. 
The following names are given to different parts of their 
structure, which, as they are not applied to other plants, it 
will be necessary to explain. The stem is called a culm , and 
in most cases it is hollow, having, however, at greater or less 
distances from each other, a number of solid joints, which are 
designated nodes. It varies much in length, even from a few 
inches to eighty or a hundred feet, as in the bamboo. The ex¬ 
ternal envelope of the flower consists of two outer scales, called 
glumes, which correspond with the calyx of other flowers. 
Within these we find another set of scales, varying in number 
in different grasses, which are called by some authors palece , 
and by others gluma. These scales correspond with the 
corolla of other flowers. Sometimes we get a prolongation 
of its midrib, which is called the awn (as in barley and bearded 
wheat). The stamens are the same as in other plants, gene¬ 
rally three in number. The ovary is solitary, with generally 
two styles and feathery stigmas.

A CASE OF TETANUS IN A HEIFER. 
By W. Shipley, M.R.C.V.S., Yarmouth. 
The subject of this disease was a two-year old Norfolk 
heifer, in fair condition. On the evening of May 6th, she 
was observed by the man who had the care of her to be 
unwell. It was noticed that she had some difficulty in 
feeding, and that the saliva w r as running from her mouth. 
This, however, was attributed to either a sore mouth or 
throat, and as such but little was thought of it. On the 
following morning, the 7th, I was requested to see the animal, 
and give an opinion respecting the nature of her illness. I 
found her located in a comfortable yard, with some five or six 
others, with whom she was endeavouring at times to feed, but 
evidently could not do so. There was a good deal of frothy 
saliva issuing from her mouth, and at first sight I was in¬ 
clined to believe that there was some local disease of the oral 
cavity, or that she had sustained some slight injury, as there 
did not appear to be any very great amount of constitutional 
disturbance. I had her caught, and in making a more 
careful examination, I found symptoms of tetanus to be so 
marked as to leave no doubt on my mind respecting the 
nature of the affection with which I had to deal. The eye
