Gives a diagram showing this curve according to Croll and also 

 according to Stockwell. For the last 40,000 and for the next 30,000 

 years the two are almost identical. Stockwell's is more nearly correct 

 than Croll's ; but there is substantial agreement. G.. A. L. 



Merk, Conrad. Excavations at the Kesslerlocb, near Thayngen, 

 Switzerland, a Cave of the Reindeer Period. Translated by J. E. 

 Lee. Pp. viii, 68 ; 15 plates. 8vo. London. 



Describes the cave and the difierently coloured deposits. The relics 

 from each were collected separately, but do not prove any difference of 

 age between them. Altogether about 30 cwt. of bones were found, 

 and determined by Prof. RUtimeyer, the main results being here given. 

 The climate of the neighbourhood, as shown by the fauna, must have 

 been more polar than during the later lake-dwelling period. Human 

 bones are absent (except a single coUar-bone) ; but weapons are nume- 

 rous ; e. g. above 12,000 flint flakes, bb arrow heads, 133 lance heads, 

 &c. are noted. The incised carvings (representations of animals) are 

 reproduced. E. B. T.
