EARLY ANTICIPATION OF PHRENOLOGY. 



THE Rev. W. D. Conybeare, F.R.S. &c, has favoured us with 

 the following notice of a curious anticipation of the modern 

 Phrenological System, bearing date as early as 1503 : it occurs in 

 an old Encyclopaedical kind 

 of Work, entitled Margarita 

 Philosopkica, printed at Fri- 

 burg in that year. The author 

 speaking of the mental func- 

 tions, says, " Sensus interi- 

 ores numero quinque sunt : 

 Sensus Communis, Imagina- 

 tiva, iEstimativa, Cogitativa, 

 et Memorativa. Horum Or- 

 gana in substantia cerebri 

 subtilissimis secernunturpel- 

 liculis ; qua? primum totum 

 cerebrum tribus distinguunt 

 ventriculis, quorum anterior 

 et medius rursus bipartiun- 

 tur: — Ima portio anterioris 



organum est Sensus Communis • 2da, Imaginativa. 

 ventriculi medii attribuitur iEstimativae ; 2da, Cogitativa? • posterior 

 vero ventriculus totus Memorativae deputatur." This is illustrated 

 by the sketch of a head divided just like one of Gall or Spurzheim's 

 models, a part of which is copied in the annexed.

COMPOSITION OF PHOSPHURETTED HYDROGEN. 



M. Rose published some years since researches on the composi- 

 tion of phosphuretted hydrogen gas, which, he observes, do not 

 agree with those published at the same time by Dumas and by 

 Buff: he has since repeated his experiments, both upon the spon- 

 taneously inflammable gas, and that obtained from hydrated phos- 

 phorous acid. 



Spontaneously inflammable Gas. — M.Rose does not state the com- 

 position of this gas by weight ; but states that he considers it as 

 composed of 1 atom of phosphorus and 3 atoms of hydrogen, or, 

 by calculation, of j a volume of vapour of phosphorus + 1£ volume 

 of hydrogen gas, condensed to 1 volume. Now as neither the 

 absolute weights of the constituents of the gas, nor those of the 

 atoms are given, we are compelled to make them out indirectly. M. 

 Rose finds that hydriodic acid combines with phosphuretted hydro- 

 gen, atom to atom, and 100 parts are stated to consist of 78*73 acid 

 -4-21*27 phosphuretted hydrogen. Assuming the atomic weight of 

 the acid to be 127, that of phosphuretted hvdrogen will, of course, 

 be 34-30 (78-73 : 21-27 : : 127 : 34-30). Subtracting then 3 = 3
