160 REVIEW. 



matters can be worked more easily, and kept for a longer time without 

 evolving any noxious smell. 



The guts, previously scoured, are put into a vat containing, for every 

 forty guts, four gallons of water, to which. 1^ pound of (Eau de Javelle) 

 oxi-chloride of sodium, marking 13° on the areometer of Baunie, is added. 

 After twelve hours of maceration, the mucous membrane is easily detached, 

 and the guts are free from any bad smell ; by this method, the process of 

 insufflation is more easily performed. 



The insufflated guts are suspended in a dry room until the dessication 

 is complete; arid, once dried, the extremities by which they were tied 

 together are cut, and in pressing the hand over the length of the insufflated 

 (inflated) gut, the air inside is completely taken out. The guts are then 

 submitted to fumigation by sulphur, in order to bleach and to preserve 

 them from the attacks of insects. After this last operation, the guts are fit 

 for use. Besides our large home supply of bladders, we import several 

 hundred thousand a year, packed in salt and pickle, from America and the 

 Continent, and the aggregate value of the bladders used in this country is 

 stated at 40,000^. or 50,000Z. 



The use of the reindeer-sinew for lashing or binding purposes on 

 implements, &c, is common from Norway and Lapland, along the entire 

 coast of Asia and America, even as low as 36° N. in California, and 

 continued on the coast-line up to the easternmost point of America, and 

 again at Greenland. Sir E. Belcher, in Transactions of the Ethnological 

 Society of London, states, he traced this custom of using the reindeer- 

 sinews continuously on the western coast as far south as the thirty-sixth 

 parallel on the coast of California, where the Mexican Indians soak it and 

 form it into layers, in which they enclose the wood of the bow entirely. 

 The horns of the bow are also moulded of it ; and when dry, it presents the 

 dull-grey translucent features of horn.

A Manual of Structural Botany, &c. By M. C. Cooke. 

 R. Hardwicke. 

 Being purely scientific, and not touching at all upon economic botanyi 

 this little work scarcely comes within the scope for notice here. But its author 

 being one of the most frequent contributors to the pages of the Techno- 

 logist, we cannot withhold some favourable mention of this manual, 

 remarkable alike for its excellent systematic arrangement, cheapness, and 

 numerous illustrations. It is chiefly designed as an introductory class-book 

 for students and operatives in the botanical classes of the Department of 

 Science and Art, of which Mr Cooke is a teacher, and will prove an excellent 

 prelude to more elaborate and expensive treatises.
