STRONGYLU8 TETRACANTHU8 AND STRONGYLU8 ARMATU8. 263 
lanks, rough, harsh coat, pulse Weak and soft, somewhat in¬ 
creased in frequency, slight elevation of temperature, respira¬ 
tions about normal, mouth a soapy feel, and pale, visible 
mucous membrane, some oedema of the hind legs, appetite 
almost entirely absent, all would nibble some at their feed, 
[but with little show of relish. All would lie down more than 
strong or healthy colts usually do, one so weak that when 
down required assistance to regain his feet. Intestinal rum¬ 
blings were frequent, and loud enough to be heard at some 
distance. There was present diarrhoea, varying in severity 
with the different colts ; the faecal matters were, some gray¬ 
ish, some greenish in color; odor foetid. On the surfaces of 
the faecal masses were in great numbers the parasites strongy- 
lus tetracanthus, also an occasional undeveloped strongylus 
armatus. The dullness and languor exhibited in the move¬ 
ments, and woe-begone expression of countenance, were well 
in keeping with the general condition of the colts. 
Diagnosis .—Intestinal catarrh, induced by intestinal para¬ 
sites, anaemia and debility as a result. 
Treatment .—Dry beds, comfortable box stalls, an abun¬ 
dant, nutritious and varied diet, consisting of oats, bran, ear 
corn, ground feed, chopped corn fodder and timothy hay, 
given fresh and as often as the colts desired, milk and eggs if 
they were to be had. Authorities usually recommend oil 
and turpentine. To commence with I ordered spiritus tere- 
binthinae, one and two tablespoonfuls, with four ounces of 
olei lini, every twelve hours, until active purgation was pro¬ 
duced. This effect was easily obtained because of the already 
existing diarrhoea. The result was an increased number of 
the parasites in the excrements, but this result, if beneficial, 
did not overbalance another effect, that of greater emacia¬ 
tion and loss of appetite. Acting on the conclusion that pur 
gation was injurious to my patients, I followed a different 
course. Tincture opii, tincture catechu, spiritus terebin- 
thinse, in a drench of milk, two or three times daily, until 
diarrhoea was checked. A powder was also given, consisting 
of ferri sulphas exsic., powdered zingiber, powdered gen¬ 
tian rt., powdered hydrastis can., given three times daily.
