362 New Work on Dying, 



duced to a similar arrangement with the rocks of tlngland 

 in the late work of Messrs. Conybeare and Phillips. The 

 upper rock is the horizontal limestone containing hornstone, 

 madrepores, branched corals, and numerous shells, partic- 

 ularly univalves. This we venture to suggest as belong- 

 ing to the great Oolite including the coral rag&c. Next 

 beneath it is a series of beds of clay and marl of various 

 colours, red, blue, &c. (perhaps the lias.) Lower down 

 is a red friable sandstone containing the salt and gypsum 

 and nodular sulphate of barytes. Very fine sections of these 

 may be seen at Rochester and Lewiston, particularly the 

 latter, where the high banks exhibit a perfect display of all 

 the strata from the limestone down to the sandstone. If 

 you cross the country in a line from Seneca Lake to the 

 Catskill Mountains — you find after leaving the limestone a 

 black horizontal argillaceous slate full of small bibalves. — 

 This slate forms the shores of Cayuga and Seneca Lakes. 

 Then advancing East to the head streams of the Susque- 

 hannah, you find a brown and yellow slate closely resemb- 

 ling the former. — As you go East, it turns red ; till you 

 finally reach the sandstones of the Catskill Mountains. 

 East of that the country is evidently transition. — We have 

 considered the slates between the two small lakes and the 

 Catskill Mountains as belonging to the coal strata ; east of 

 which we find, among other rocks, limestone in inclined 

 strata, abounding in shells and hornstone, (perhaps the, 

 Mountain Limestone.) Our principal object in these re- 

 qiarksis to fix the exact locality of the salt formation be- 

 tween the coal strata and the horizontal limestone, and to 

 ascertain the position of the latter rock in the European 

 order. We offer these remarks only as suggestions, and 

 we should be happy if they might aid any one in arriving 

 at more definite conclusions.

7. New Work on Dying. 



Wm. Partridge of New York has just published a Prac- 

 tical Treatise on Dying, &ic. Mr. P. is an experienced dy- 

 er from Gloucestershire, England, and his work bears the 

 marks of good sense and practical acquaintance with the 

 subject treated of. His remarks on the defects in our 

 woolen manufactures are interesting.
