supported l»y our personal exainination of the casts, together with 

 the infonnation courteously supplietl us h\ Dr. C. H. Mollisoji, 

 Lecture)- on Forensic Medicine in this I'niversity. that in his 

 opinion, and t'runi personal ohsei-vation, the auKjunt of erior due 

 to post iiiortdii oedema after ileath l)y hanging and tlie otlier 

 incideJital causes ix'ferred to might aimtuiit to as much as 10- lo 

 mm., nIiouM, We tliiidv, convince tlie most seejitical tliat the culiic 

 capacity of brain cannot be estimated from tlie uncorrected figui-es 

 of the casts. 



This being tlie case, the prol)leni ajose in "what way was the 

 necessary coriection to be made. Our first intention Avas to make 

 the cid)ic capacity calculations four times, first from the uncor- 

 I'ected hgures of the casts themselves, mid for the remaining three 

 calculations to deduct 4, 7 and I I inillimeti-es respectively from 

 the lengths, breadtlis, and heights. \\\ working out the true 

 means, standard deviations an<l prnl);il)]e I'rrors of these several 

 series of calculations, it was ho])ed that we should, by the applica- 

 tion of general pi-inciples to the )-esults so attained, be enabled to 

 foi"m a pi'ctty accurate opinion as to which series of deductions 

 gave the most probable result. 



On further reflection it seemed to us that any such procedure 

 would be at best highly em])iiieal. and on medical grounds was 

 open to the serious objection that under no jjossilnlity could the 

 oedenui affect all three diametral measurements equally, certainly 

 not the height in which one of ilie fixed ])oints is the meatus 

 acusticus externus. We, therefore, decided to abandon any such 

 irrational method of establishing tlie correction, and to seek for 

 some more scii'iitiflc method of effecting our purpose. 



AVhile exauiining the literature of the suljjecit for our previous coiii- 

 munication (1). we had read a shoi't ]iapei- liy Dr. (i. IJ. (ii'iflitlis. 

 De])iity .Medical Officer in H.M. I'lison Service' in England, on 

 the " -Measurements of one liundi\'d and thirty criminals '" (o), 

 and liad noticed that in tliis he records the head lengths, bi-eadths 

 and heighls of '.\(\ male English iiiiii(K'reis incai'cerated in I'ark- 

 I'Mst I'risoii. England. 



.\s (iriflitlis's ])a])er is strictly technical, and deals with nothing 

 more than the mere record of his iiicasiiretiieiits, wt' do not know 

 whether these I'lnglisli criminals were umler senteiut- of death, or 

 whether they were i>'])rieviMl itmnlereis serving a lifi' sentence in 

 commutation of hanging, but in view of the conipai'atively larire 

 numiu'i'. it is oidv reasonable to assume that they "were )'epriev-.><l 

 murderers. What, howevt'r, is for our jmrpose much more ;iii- 

 poitant, is that ( Irithtlis's measurements were recorded upon 'ho
