502 Dr. Hofmann on the Metamorphoses of Indigo. 



The glenoid cavities are flatter, more widely separated, and not 

 so well-defined as in the European generally, and a diiFerence corre- 

 sponding to this is seen in the lower jaw, where the condyles, besides 

 being more widely separated from one another, are also more rounded 

 in form, allowing of a greater degree of lateral motion. In corre- 

 spondence with this fact we also find that the pterygoid processes of 

 the sphenoid bone, especially the external plates, are widened and 

 enlarged, extending farther outwards, aflrording a greater space for 

 the attachment of the pterygoid muscles, whose duty it is to perform 

 the lateral or grinding motion in mastication. I mentioned above 

 the corresponding fact of the teeth being much worn down. 



The ridges for the attachment of the muscles on the palate bone 

 are well-marked, and viewed from below it is seen that the alveolar 

 processes do not project so much from the horizontal part of the 

 palate ; that is, that the entire hard palate presents a general curve 

 throughout, instead of being at first plane with a sudden bend, or 

 almost an angle, which is seen at the point where the alveolar pro- 

 cesses are given off in the generality of European skulls. 



These skulls of the Finns and Lappes are very solid and heavy. 



Although this description of the Finnish skulls corresponds in 

 very many respects with that given by Dr. Hueck, yet the examination 

 leads us to an exactly opposite conclusion, viz. that there are very 

 many points in common between the Finn and the races characterized 

 by the pyramidal-shaped skuU, and the conclusion with regard to the 

 Lappe corresponds to that which was published by Professor Blu- 

 menbach. We are hence able to lay down, that there is no important 

 difference between the skulls of the Finns and Lappes, but that, on 

 the contrary, there is a very great resemblance between them ; that 

 altogether they are more nearly allied to the Hyperborean form than 

 to the European ; and that if any difference does exist between them, 

 it is that the Finns approach more nearly to this conformation of 

 skull than the Lappes.

Action of the fused Hydrate of Potash on Dichlori- 



SATINE. 



B. Dichlor aniline [Amachlophenise) . 

 ipRDMANN has proved by direct experiment that chlori- 

 -*-^ saline cannot be converted into dichlorisatine by the 

 further action of chlorine on this substance sus[)ended in 

 water. I have had frequent opportunities of convincing my- 

 self likewise of this fact. If an alcoholic solution be employed 

 the decomposition proceeds too far, and products of oxidation 

 are obtained, viz. chloranil, chlorophenussic acid, &c., which 

 no longer belong to the isatine series.
