TlllilK NA IT !:\l. DOW EKS UF Ul MISI'ANt K. .IS. A. Reid, F.R.C.V.S., D.V.U., F.R.S.E.) A short lime ago I ice i-ed, L"U.ugh Mr Hubbard, Inspector of Sto. k, MaslertoA, two Bpecim'ms of dot- taKen from the nasal cavities .>:" n. -neep. Thesi had been brought by a farmer to the local ollice of the D | uf..ent for identilieatioii. They prov. i cr. examination to be larvae of the Bheeplly (F.-trus ovii).

The parasites bad hf« i n placed l»y Mi Hubbard at tbout noon ou tbe ±2nd November in ""a glassstoppered bottle containing 1 pe cent [ormalin solution. On leccivuig d,e bottle at the laborv. iry two days Inter 1 was surprised to tied on removal from the roluUon th-jit one was alive. On being he'd in the band or exposed to sunlight on the laboratory bench it slowly extended lUelf, and ilien commenced to move i-way quickly. The remaining hot was dead. In order to ascertain bow long these nt'utures could support life in sueh an int derable medium, 1 replaced the live hot in the formalin -obi'iin, removing it eaeli day to see. whether it showed any signs of life. Ine wvroth of the hand or sunlight seemed to ha\e a revivifying! e'lcct, for tip till the 2Sth November, or 'le »<" tnth day after complete burner sion i". the solution, it still remiim-d a <\f. The natural powers .•{ .♦isUru' of sucii lowly forms are enormous and it may w< 11 be contended '3V n in this ease that the parasite final'y succumbed from prolonged t»posur? ir unsuitable environment rather than to the poisonous effects of ihe fi'nulin. This observation serves to i'lustrate how ineffectual is ike uunv.nw ration of drugs designed to destroy thu-e parasites during the life of their host, and should eause fanners to pause before employing any of he jUijk lenv edies which are advertised S»o'"> timo to time as cures for bots.
