pelago may be regarded as the origin of the same maladies it 

 produces everywhere ; but that in Egypt it gives rise to results

 malignant fever, so as to give it all the characters of the plague, 

 and this cause exists only in that country. 



NEW PUBLICATIONS. 



1 * The Physical and Intellectual Constitution of Man consideredy 

 By Edward Meryon, F. R. C. S., &c. London : Smith, Elder. 

 & Company. 1836. 8vo, pp. 240. 



This agreeably written and interesting little volume we recom- 

 mend to the particular notice of our readers. 



2. A Geological Sketch of the Tertiary Formation in the Provinces 

 of Grenada and Murcia in Spain, S^c, By Brigadier Charles 

 SiLVERTOP. London : Longman & Rees, 8vo, pp. 236, with 

 plates. 



Silvertop is one of that active and enterprising corps of military 

 officers who of late years have devoted their time to the advance- 

 ment of geology. Like Murchison, their geological chief, Silver- 

 top is not a mere museum or closet, or society geologist, but an in- 

 defatigable and successful labourer in the field, as is shewn by the 

 interesting work now before us, which we doubt not will be prized 

 by all true lovers of practical geology.

 M. D. F.R. S.E., Member of the Wernerian Society, &c. Black- 

 wood & Sons, Edinburgh, 8vo, pp. 119, with plates. 1836. 



Of this successful ascent to the highest point of Europe some ac- 

 count has already appeared in this Journal ; but the volume before 

 us contains many valuable and interesting additional details, and also 

 a luminous history of the observations of all preceding travellers 

 wlio have reached or attempted to reach the summit of Mont Blanc.

 mena. By VV. M. HiGGiNS, F.G. S., Lecturer on Natural Phi- 

 losophy at Guy's Hospital. London : Orr & Smith. 1836.
