and mesentery showed that two fatty tumours existed on the 
latter, near to the attached border of the intestine. They 
were placed one on either side of the mesentery, and directly 
opposite to each other—a peculiarity which we have never 
before witnessed. One of the tumours had, seemingly by its 
weight, torn through the mesentery contiguous to the place 
of its location; and although having only a very short pedicle, 
it had nevertheless encircled the bowel and produced the fatal 
strangulation. 
This tumour was rather larger than the other, and more 
elongated in form.]

The next plant we shall proceed to describe as yielding a 
supply of food for our domestic animals, is the potato (Solanum 
tuberosum), which, although much more extensively cultivated 
as food for man than animals, is nevertheless well worthy of 
our attention, as it will enable us to bring under notice 
another great subdivision of Exogens, and to the veterinary 
surgeon one of the most important natural orders in the 
vegetable kingdom. 
The Solanum tuberosum (potato), like all the other plants we 
have noticed, whose roots or stems yield food for animals, be¬ 
longs to the class of Exogens, and to the only remaining subdi¬ 
vision of that class not yet described, viz., Corolliflora: “ Flowers 
furnished with both calyx and corolla, the latter consisting of 
united petals/' and to the natural order Solanacece (nightshades), 
which may be known by the following characters :—“ Calyx 
five-parted, persistent, inferior ; corolla monopetalous, hypo- 
gynous ; the limb, five-cleft, regular or somewhat unequal, in 
aestivation plaited or imbricated; stamens inserted on the 
corolla, as many as the segments of the limb, with which they 
are alternate ; anthers bursting longitudinally, rarely by pores 
at the apex; ovary two-celled, with two-polyspermous pla¬ 
centa ; style continuous ; stigma simple; pericarp, with two or 
four or many cells ; either a capsule w r ith a double dissepiment 
parallel with the valves, ora berry with the placentae adhering 
to the dissepiment; seeds numerous; herbaceous plants or
