This book is a great resource for those interested in veterinary helminthology and entomology. To use it, simply start reading from the beginning to gain knowledge about the subject. When handling the book, be gentle due to its age and the signs of wear. Store it in a dry and cool place to prevent further damage. Avoid eating or drinking near it to keep the pages clean. If you need to make notes, use a bookmark or a piece of paper instead of writing directly in the book.
