veau, Percivall, Tomes, Gamgee, Leidy and others, and will be found a very 

 useful and readable compilation of authorities upon all the topics above named.

 all the technical terms ordinarily used in scientific works upon the subjects treated. 

 The student of comparative anatomy, as well as the veterinary surgeon, will 

 find much of interest to him in this work and will be put upon the track of much 

 more by the copious quotations from notes and references to the noted authors 

 named above and many more of equal standing.

Prof. Morangoni shows by a conclusive set of experiments that moist air is 

 not a conductor of electricity. He proves that the loss of current in telegraph 

 wires and the want of action in electrical machines during misty or wet weather 

 is due to the condensation of moisture, carbonaceous deposits, adherent dust, 

 spiders' webs or the contact of branches of trees. 



The silk industry is reviving in Louisiana, the news of this spring's hatching 

 being very encouraging. Interest in the culture is growing, and inducements 

 are offered to silk workers to come from France and engage in the business. 

 The first exports of silk from Louisiana were made as far back as 17 18. The 

 culture of silk is also being revived in South Carolina and Georgia.
