1878.] E. S. Brough — Sectional Area of Liglitning Bods. 195 



The fourth was entitled Hamir Easa. It is a small work of 54 

 folia 4to, written in the ballad style of Chand's Prithviraj Eayasa, the 

 language being old Hindi, but not quite so archaic as that of Chand's. The 

 hero of the ballad is HamIr, the renowned sovereign of Eanthambor, whose 

 name has served as a title of honor to many an Indian chief since his time. 

 He lived in the time of 'Alauddin, against whom he waged a devastating 

 war for many years. The author of the work is Mahesa who was the family 

 bard or Bhatta of the hero. The MS. is dated Samvat 1861, and is seventy- 

 four years old. Dr. Mitra also submitted an English translation of the 

 work by Babu Brajanath Bandyopadhyaya, and suggested that, after 

 revision, it be printed in the Journal.

(Abstract.) 



In this paper the author shows that the usually accepted statement

 a copper rod is erroneous and that the proper proportion is 8 to 3.

Mr. W. T. Blanfoed said that he had a few years ago, paid some atten- 

 tion to the genus JVesokia, but at that time he had not sufficient materials 

 for a complete understanding of the species. Indian Zoologists were in- 

 debted to Dr. Anderson for working out a very difficult subject. 



Although Mr. Blanford was not quite convinced of the identity of 

 Arvicola indica with Nesolcia hardwichei, he quite agreed with Dr. Ander- 

 son that the specific name indica should be abandoned. The original figure 

 of Arvicola indica in the " Illustrations of Indian Zoology" was probably- 

 taken from a bad native drawing of an ill-stuffed specimen. The name
