size of the maxillary sinus ; and, 2c?(^, By the amplification which 

 the fluor of the nasal fossa undergoes, all of whose modifications, as 

 is well known, are intimately allied with those of the roof of the 

 mouth, and so with the gustating chamher. 



These are the principal changes which the crania of the Mongolian, 

 Malayan, and Ethiopic races have exhibited when compared with 

 European heads ; and in coming to these conclusions, we have em- 

 ployed the most scrupulous attention in comparing the different crania 

 we could command. 



We now remark that these changes of form, effected on the cra- 

 nium and sensorial cavities, become more conspicuous in the Chinese 

 than in the Baskir, in the Malay than the Chinese, and in the Negro 

 than the Malay. The Negro appears to be the farthest removed from 

 the Caucasian tribe ; but here we take occasion to protest against any 

 thing like apologizing for slavery, than which nothing is farther from 

 our intention. 



As to the constancy of the distinguishing characters which we have 

 pointed out, future inquiry alone can confirm it, the materials which 

 we could use being far from ample. The same remark applies to the 

 encephalic modifications, which correspond to the changes in the form 

 of the cranium, upon which we have insisted, as all anatomists are 

 aware of the caution which must here be exercised, the subject of 

 the comparative encephalotomy of the human races being still in its 

 infancy. — Comptes Rendus, No. 2. 12 Juli/ 1841. 



12. Glarine and Infusoria in Mineral Springs at Stockbridge, 



Edinburgh, Mo fat, Sfc ^Mr Lankester found the conferva nivea of 



Dillwyn in the hepatic spring on the river Leith, near to Stockbridge, 

 Edinburgh. He has also found it in the wells of Moffat in Dum- 

 friesshire, Gillesland in Northumberland, and Middleton and Croft in 

 Yorkshire. At Moffat he found great quantities of the substance 

 called glarine, and was convinced of its organic nature. At Moffat 

 also he found a pink-coloured deposit in the drains outside the wells, 

 and on submitting it to the microscope he found that it was produced 

 by an animalcule, but much smaller in size than those which pro- 

 duced the coloured sediments of Harrowgate and Askern. It had 

 the characters of a monas, and was not more than xjj^g of an inch 

 in diameter. 



13. Change of colour of the Lepus Amcricanus. — Col. Smith re- 

 lated an instance of a number of specimens of the Lepus Americanus 

 being shipped in America quite white ; at the end of twenty days they 

 had turned quite brown. The hairs were not shed, and the change 

 must have taken place in the hairs themselves.
