9 
times, though very erroneously, ascribed to an affection popularly 
known as Gid, Sturdy, &c., of which “ one of the most striking 
symptoms is the rotatory movement of the affected beast.” Though 
several of the disordered movements are similar in the case of this 
attack and that of the presence of Nostril Maggot, it is to be 
observed that “ turning in a circle does not take place in this 
[Nostril Maggot] disease. The latter is nearly always accompanied 
by nasal discharge and snortings, which do not occur in true 
Gid,”* caused by Ccenurus cerebralis. 
Prevention and Remedies.— The most simple method appears 
to be that noted by Dr. Cooper Curtice in his work previously 
quoted :— 
“A practical means of prevention consists in smearing the 
noses with a mixture of equal parts of tar and grease, or of tar and 
fish oil, or of tar and whale oil. The better way is to apply the 
preparation directly by a brush. Some recommend smearing the 
salt and grain troughs with the mixture, expecting the sheep while 
feeding to get more or less on the nose. This method is not 
thorough enough. Fish or whale oil alone is also recommended.” 
The following ointment is advised :— 
“ Beeswax, one pound; linseed oil, one pint; carbolic acid, 
four ounces. Melt the wax and oil together, adding two ounces of 
rosin to give body, then, as it is cooling, stir in the carbolic acid. 
This should be rubbed over the face and nose once in two or three 
days during July and August. 
“ All grubs seen on the ground should be crushed. Heads of 
slaughtered sheep should be cared for so that mature grubs cannot 
escape to the ground. Sheep-yards should be periodically cleaned 
and sprinkled with lime.” 
In regard to remedial measures, especially by operation, these do 
not come in the scope of the present observation, and more particularly 
as for such cases veterinary advice and assistance would be requisite. 
Probably, also, though the concluding words of the sentence are not 
pleasant, Neumann’s advice, as suggested by Dr. Cooper Curtice, is 
“ the soundest to follow, except in the cases of breeders of valuable 
sheep”:—“ At all times, if the number of animals affected is con-
