upon the bronchi, and cause more serious trouble. The French 

 discovered that garlic would aid the fowl to disgorge the eggs. 



About twenty persons entered into the discussion that fol- 

 lowed, in which the Professor took part, and answered ques- 

 tions. In reply to one, he said that pin worms found in horses 

 breed near the outer passage of the rectum, while in the indi- 

 vidual the}- must have a breeding stage outside. The inquirer 

 had found a good remedy in sweet or lard oil applied to the 

 rectum. Mr. "Ware had mixed over a quart of oil, with a horse's 

 provender, and found it very effective. Mr. Holt, of Andover, 

 had given arsenic about the size of a three ceut piece, to his 

 horse, to eradicate pin worms. The horse was stiff afterwards, 

 but recovered. Dr. Cogswell, of Bradford, said that he had 

 given a horse five grains of arsenic at morning, and five at 

 night, without hurting him a particle. It would often benefit 

 the system. A great many remedies were found out by acci- 

 dent. Indian meal would stiffen a horse up more than arsenic. 

 The best thing to destroy lice and ticks, said "Warren Brown, of 

 Hampton Falls, was carbolic acid — one pound of carbolic crys-

 and said that thymo-cresol was another good remedy. 



Professor Fernald said that sulphuret of potassium, from two 

 to four ounces to a gallon of water, two for tender skin, and 

 four for tough hide, would be found perfectly safe. He urged 

 special caution, that no mistake be made as to kind. Sulphuret 

 is of a dark bottle green in color, is perfectly harmless, but 

 cyanide of pottassium is white and a deadly poison. 



Afternoon Meeting. Professor Fernald addressed on "In- 

 sects injurious to our Farm Crops," mentioning first the eye 

 spotted bud moth, which appears on the apple-trees when the 

 buds are swelling. Its larva eats into the bud, causing the 

 twig to shoot out laterally, and then another moth comes along, 

 eats into the new bud, and causes a shoot in another direction, 

 thus giving to the tree a scraggly appearanee. He had found
