Ik 6 f fle j - 0in /’ was , an °P ellin g about four inches in 
height and about six inches in length, through which the entire 
visceral contents of the abdomen had escaped, and lay ouSde 
t le calf s body among the foetal membranes. The opening 
through which the intestines had come, had at some previous 
time been much larger, as quite an area of cicatrization was 
ysibk on the surrounding skin. The intestines were small and 
ill developed, their structural tissues being extremely delicate in 
texture and of a pale red color. They contained a small 
amoun of meconium. The skin and hair over the entire body 
was fully developed, as was the posterior part of the body, with 
ie exception of the legs. The calf was a female and all the 
organs of generation were fully developed and occupied their 
normal position within the body. 
The owner stated that about ten days previous to her time of 
calving, the cow had jumped astride of a fence and alighted 
upon her abdomen ; he thought that the malformation of the 
calf was due to this accident. The undeveloped condition of 
e intestines and the left hind limb, would preclude any such 
theory. Again if the calf’s spine had been thus violently in¬ 
jured in utero, death would undoubtedly have occurred On 
the contrary, the calf was without doubt alive at the time par¬ 
turition began The bones of the spinal column were also 
tirmly united by anchylosis, which goes to show that the case 
was one of arrested development, due, without doubt, to the 
position assumed by the foetus in the womb. The cow recov- 
ered completely. 
POISONING BY EOCO WEED. 
By Coleman Nockolds, M.D.,V.S., Cadillac, Mich. 
During the year 1892 I took the opportunity and went with 
a friend who was going to take his herd of about three hundred 
lalf-breed mares, geldings, colts and young mules from southern 
fexas to the plains in northwestern Texas for the summer 
grazing. We started during April. The animals with the ex¬ 
ception of the colts were all rather thin, having had but scanty 
grazing during the winter, and once they were up to where the 
grazing was good lost no time in making up for their short ra¬ 
tions during the past winter. In that particular section of coun¬ 
try we noticed quite a quantity of that little weed growing 
amongst the grass, which the cowboys and Mexicans call loco 
Klit X1Can meaning crazy), a little plant growing from 
six to eighteen inches in height, with pale green hairy leaves
