ubi jure meliore gemere possem. Tales autem agendi fationes 

 libenter cedendae iis, qui ejusmodi artibus utuDtur. Satis est, 

 ut lectoribus Florae submittamus succincteque examinemus novas 

 auctoris assertiones (quoad* ut dicit, „some passages quoted 

 from my two last lichenological brochures had been misunder- 

 stood by my — critic, or wrongly dealt with"); capita persequa- 

 mur ordine numerisque, quibus dantur in Grevillea. 



I**,Hic^) mirabile dictu, in hypothesin algo-lichenicam novam 

 incidimus: „The truth is, — it is difficult to deny that many 

 Lichens during the first stage of their life are connected para- 

 sitically with some of the inferior Algae. At a later period, 

 howewer, when the Alga, assuming the form of Gonidia, beco- 

 mes included within the tissue of the Lichen, the connection, if 

 still kept up, can hardly continue to be considered as parasitical." 

 Lubet autori, ut sic sit! Ita theoriae finguntur (negotium sane 

 facile est) potissime dicendae libidines vis imaginandi. Naturam 

 consulere observationibusque incumbere superfluum est; conve- 

 nit insuper personali videndi rationi observationes contrarias 

 plane negligere vel minimi facere. Nescire vero videtur anctor, 

 plurimos Lichenes gonidia baud inclusa habere, cur opinio ejus 

 mox fuse lateque extendenda esset et recta via in Schwendeneris- 

 mum verissimum perducit, cujus sic manifeste se asseclam esse 

 (forsan non conscium) ipse indicat. ^) 



1) „Dr. N. takes occasion — to develope his opinion" Wedd. Opiniones 

 non dedi, sed observationes, de quibus Dr. W. hanc exprimit opinionem; 

 „As regards Dr. N\ special objections to an Algo-Lichen hypothesis, J do 

 not see that they are in any may conclusive, not one of them really coming 

 to the point" Hoc in memoriam revocat illud Frieslanum „inter omnia no- 

 strae aetatis scrlpta minime placent Nylandri". Evidenter auctor gloriam 

 persequitur Friesianam et Lindsayanam. Demonstravi autem, elementa fiia- 

 mentosa Lichenum non esse eadem ac hyphas Fungorum; demonstravi, goni- 

 dia primitus oriri (in thalli primis initiis) intra cellulas clausas thalli, nee 

 extrinsecus ullo modo advenire. Quod satis superque jam eat ad omnem 

 Schwendenerismum refellendum. Dr. W. (non sine causa argumenta vaga 

 optima aestimans) loquitur de „many facts lately adduced," sed quaenam sunt 

 caute non memoravit, nee revera talia ulJa adsunfc. Prima germina Lichenum 

 et Fungorum in corpusculis qualibuscunque infixa conspiciuntur. — Si non, 

 ex doetrina Friesiana ampliata, gonidia parasitas sisterent thallorum, alia 

 opinio quae vellet thallum apotheciaque parasitas sistere gonidiorum etiam 



luagis est absona. 



2) Inter animadversionesauctoria adestquoque ilhid: gonidia sicut ^instru- 

 menta" nutritionis admittit, non vero sicut organa — „a8 instruments (I dare 

 not say organs) of lichen nutrition**— quae distinctio pcrtinet ad inventa ejus 

 physiologica. Hucusque in scientia organa erant instrumenta vitalia.
