 These remarks will be more readily understood by reference 

 to the annexed outlines, which are taken from a cast of one of 

 the skulls obtained by Mr Pentland. 



Dr Goddard has suggested to me that the deformity observ- 

 able in this series of crania, might have been produced by the 

 action of rotary bandages alone without the use of splints or 

 compresses. I admit the possibility of this result in some of the 

 heads, but think that in others there is satisfiictory evidence 

 of the use of the splint or compress, especially on the os frontis. 



I have in my possession six casts of heads and three skulls 

 of these people, all of which present the peculiarly elongated 

 form in question.

My Dear Sir, — Knowing that you will be glad to hear of 

 my safe arrival amongst the Alps, and of my farther proceed- 

 ings, I hasten to give you an account, in a few words, of what 

 I have as yet done. Finding the season more than usually 

 advanced, I hastened to reach Chamouni, in order to ascertain 

 whether the Mer de Glace was as yet accessible in all its ex- 

 tent ; and I arrived at the Montanvert on the 24th June, and 

 remained there for a week. I was fortunate enough to con- 

 vey all my instruments to their destination, without, I believe, 

 injury to any one of them. The Mer de Glace, so continually 

 visited by the curious, but so little studied, seemed to me to 

 offer great advantages for the prosecution of the objects which 

 I proposed to myself. At first sight it appeared to me steeper 

 and more crevassed than I recollected it to be, and I doubted 

 for a moment whether it was adapted for my experiments ; 

 but that doubt vanished upon closer examination ; and in the 

 course of the single week which I have been able to spend 

 there, being favoured by most excellent weather, I have ob- 

 tained results so far definite and satisfactory, that, imperfect 

 as they necessarily are, and only the commencement of what
