MICROSCOPICAL NOTES. 



The Great Salt Lake. — This is the title of a book just 

 issued from the D«seret News office, Salt Lake City, by 

 Dr. J. E. Talraage, Professor of Geology in the Univer- 

 sity of Utah. The great interest and value of the book 

 will appear from the chapter on life in the lake reproduced 

 by us on pages 217-224. Other chapters relate to the geo- 

 logical history of the basin, the great economic import- 

 ance of the salt, tlie different pleasure resorts, the history 

 of man's contact with the region, and many other points. 

 The 116 pages of text are illustrated by 22 beautifully pre- 

 pared half-tones and provided with flexible cover. We are 

 not advised of the price but think our readers will be safe 

 in enclosing fifty to seventy-five cents for a copy, either 

 to Dr Talmage or to the Deseret News.

Microscopic Inspection of Pork. — In 1881, the importa- 

 tion of American pork into Germany, France, and the prin- 

 cipal countries of the continent of Europe was prohibited 

 on the assumption that it was infested with trichinae, and 

 was therefore injurious to health. Although it could not 

 be shown that American pork had caused disease it being 

 manifestly more wholesome than European pork, and not- 

 withstanding the most vigorous protests by this Govern- 

 ment, the trade was crushed and destroyed. The year be- 

 fore the prohibition went into effect the United States sold 

 to France 70,000,000 pounds of pork, and to Germany, 45,- 

 000,000 pounds. For ten years thereafter American pork 

 was shut out of nearly every market of continental Europe, 

 and the prohibition was not raised until the Bureau of Ani- 

 mal Industry began the microscopic inspection and certi- 

 fication of pork destined for those markets. The trade had 

 to be built up anew over the prejudices that had been so 

 firmly rooted, and it has been a slow and difficult process.
