■iTsak injeclion of the hydrargyrus muriatiis more frcqucntlv 

 iuccefsful than any other. One grain to fix ounces of 

 water is quite ftrong eiioughto begin with, and the ftrength 

 n:ay be gradually augmented, in proportion as the urethra 

 appears capable of bearing it. The practitioner muft not 

 leave off the injeclion as loon as the difcharge ceafes ; for 

 if he does fo, the gleet will generally recur, 'i'he plan 

 fliould ftillbc followed up for about a fortnight. 



When gleets are to be cured by bougies, it is neceflary 

 to wear thcfe inftruments about a month or fix weeks 

 before any dependence can be put in the permanence of the 

 cure. 



Neither the furgeon nor the patient fnould be deterred 

 from perfiiling in the trial of irritating injeftions or bougies, 

 by the circumllance of their appearing to increafe the dii^ 

 charge at firft;. Tliis they always do. 



Mr. Hvmter thought that moderation and regularity in 

 diet were conducive to the cure of gleets. So is a quiet kind 

 of life in the generality of cafes, but there are inllances in 

 which gleets feem to be benefited and cured by rough excr- 

 cife on horfeback. 



A return or an increafe of a gleet is very apt to be tl:e 

 confequence of intcrcourfe with women, and the patient 

 often thinks that he has received a frcfli infection. Mr. 

 Hunter thought that the cafe might be difcriminatcd by the 

 fliort time which intervenes between the connection and the 

 re-appearance of the difcharge. Gleets are often fo exceed- 

 ingly obftlnate, that the furgeon cannot be informed of too 

 many modes and principles of cure. On this account we 

 deem it right to mention that gleets feem to be curable on 

 the principle of counter-irritation. Hunter has feen a gleet 

 flop on the breaking out of two chancres on the glans penis, 

 and the difcharge has been known to ilop as foon as a bliftcr 

 was applied to the under part of the penis. 



Gleets have likewife been cured by eleftricity. 



Women ai'e hable to gleets, and the difeafe being iltuatcd 

 in lefs irritable parts, whatever injections ai'e ufed, may be 

 made flronger than for male patients. 



It is almoil unneccflary to remark, that balfams and tur- 

 pentines, internally given, can have no ipecific effect on the 

 parts affeclcd in women, as they liave on the urethra in men. 

 Hence it would be abfiu-d to prefcribe fuch medicines ior 

 female patients.

GLEICHEN, Frederic vox, in Biography, was 

 born in the year 1714. He v.-as intended and educated 

 for the profeffion of arms, and fpent the early part of his life 

 as an officer in the fervice of Bayreuth, and was dilllnguiflied 

 bv his attention to military difciphne. He rofe to the raiik 

 of lieutenant-colonel, and obtained the favour of tlie mar- 

 grave. His honours did not fit cafy upon him, lie lighe<l 

 for retirement, and in i 756 his wiihes were accompliihed ; 

 he obtained a dilmiiHon from the fervice v.-itli a handfomc 

 penlion, to which was afterwards added the rank of pnvy 

 counfellor. He now had leiliire to dillinguilli liimfelf as a 

 ^hilofopher, a nauurahft, and a writer. His attention was 

 accidentally excited to microfcopical obfervations, and not 

 Xatisficd with the inllruments already in exillcni-e he con- 

 ftrufted an univerfal microfcopc, with which he combined 

 the folar microlcope. His principal obfervations relate to 

 feminal animalcula, and infufion animals : lie v.-ould fit day

after day at his glafs, and was always difpleafed if he ex- 

 perienced any interruption while engaged in his favourite 

 purfuit. By daily pradtice he had acquired uncommon 

 acutenefs of fight, whicli was of the grcattll advantage to 

 him in his refearclies. Tliougli he had an ardent attach- 

 ment to fcience for the love of it, yet he dcvifed various eco- 

 nomical plans, from wliich he cxpeftcd to derive great emo- 

 lument, but they were the fchcmcs of a tlieoriu, and did 

 not prove of real advantage cither to himfelf or the world. 

 He died in June 1783, leaving beliind him numerous workt

 llrufture and phyfiology of the parts of frnftification in 

 feveral plants, puhlilhed at Nuremberg, in foho, with 

 coloured plates, in 1764. As tlie feeds of ferns wen- 

 among the fubjetts to whicli Baron Gleichen paid great

Elf Ch. Capfules in a fimple, concentric, orbicular feries ; 

 eacii feries contlitu'ing a round feparate dot, on the back of 

 the leaf. Cover none. 



This genus was firft founded on the OnorUa polyttotTnidft 

 of LinniFus, an elegant and fingular fern, native of the Cape 

 of Good Hope. In this the capfules arc ufually three, nrclr 

 four together, half immcrfed in the uitder fide of the frond, 

 and as each burils by a longitudinal filfurc, they all together 

 liave exactly the appearance of a ling'e capfn'c, of three 

 cells, and three valves, the partitions feeming to originate 

 •from the centre of each valve. Traces of a jointed ring 

 appear on fome of the valves only, and rather refemblc the 

 corrugations of thofe fcri'.s termed J^'iriouJIy m.rvlatetf. 

 Several other fpccics, ftriclly allied to the origina! one in 

 habit and appearance, fo as to be at firll fight fcarcely dif- 

 tinguilhable from it, have been found in New Holland, 

 and have been defined by Dr. Swartz and Mr. Brown. 

 In thefe the capfules arc not immerfed in the leaf, though 

 each feries ftands in a flight depreflion. In G iluaifti of 

 Brown there are only two together ; in others three, four, 

 or even fix. Thefe new difcovercd fpccies evince the pro- 

 priety of Mr. Brov.n's meafure, of reducing the I'.'rrUnfa 

 of AVilkleiiow and Swartz to GlticLii'ia, as tlicir fruAifica- 

 tions exactly agree. nicrjKOptcns of Bornhardi docs not 

 in our opinion fo well afibrt with llicm, having an irregular 

 accumulation of ftalked capfules in each dot, though its 

 habit is pi-ecifely that of McrUnfi.t. Mr. Browni, having 

 examined thefe feins alive, determ.incs them to he fur-
