a 2 CK) solution of corrosive sublimate used twice daily for five days, and 

 doses of albuminous water aud raw eggs on the stomach to counteract 

 any injurious results from mercurial salivation. One of these living mag- 

 gots was fed on raw beef and became a pupa, five days later developing 

 into the perfect fly, original natural size figures being given of this 

 pupa and fly. The other case, observed by the writer himself, was 

 caused by the larvte of Sarcophaga carnaria, the common flesh-fly, 

 and though a very bad case was overcome in a few weeks; by what 

 treatment is not stated. Injections of a five per cent solution of carbolic 

 acid had been of no avail. Three original figures of one of these larvas 

 are given showing respectively the magnified larvae and its anal and 

 capital segments still more enlarged. 



Article III considers the clinical history of myiasis, dividing it into 

 (1) myiasis of wounds, (2) myiasis of nose, ears, eyes, and vagina, and 

 (3) myiasis of the intestines. The first two are caused by Sarcophagidce 

 aud Muscidfc being attracted to putrid or septic wounds, or to an oflen- 

 sive or purulent discharge from the various orifices of the body and 

 depositing their eggs or larvae therein. Such cases, after removing all 

 the larvae possible by mechanical means, are best treated with the cor- 

 rosive sublimate injection (except in wounds), injections of chloroform 

 diluted with sweet milk, or injections of citric acid or lemon juice. The 

 insufdation of iodoform has also proved satisfactory in several cases. 

 The last division of the subject, myiasis of the intestines, is caused by 

 the Anthomyidce depositing their eggs in spoiled vegetables which are 

 afterward eaten in a raw state, as in salads. The same treatment should 

 be used in this cam as in helminthiasis. — C. H. T. T. 



CODLING MOTH REMEDIES. 



D. B. Wier, in the Orchard and Farm for May 15, after referring to 

 the successful spraying with London purple for the Codling Moth, 

 reported by Prof. M. H. Beck with, of the Delaware Agricultural Col- 

 lege, and of the similar favorable reports from other Agricultural 

 Colleges and Experiment Stations, expresses the belief that this pest 

 of the Apple and Pear, and also the Curculio of the Plum and Peach 

 can by this means be effectually controlled. He gives, also, a mode 

 of destroying the Codling Moth, which he claims to be of great value 

 where the apples are carried to a shed or barn to be assorted and 

 packed. He proposes to kill the myriads of worms which leave the 

 apples while in such places to spin up in crevices of the building by 

 fumigating with some gas, such as sulphide of carbon, fumes of burn- 

 ing sulphur, or the hydrocyanic acid gas used against the Cottony 

 Cushion Scale. By making the apple shed or house of rough lumber, 

 with plenty of crevices for the worms to spin up in and yet as near air- 

 tight as possible, it will be feasible, he says, to shut up and thoroughly 

 fumigate in March, destroying the insects ; or in smooth-plastered 

 houses, traps of old boards and shingles, rags, etc., could be arranged,
