The two lenses on a compound microscope are called the objective lens and the eyepiece lens. The objective lens is located near the specimen being observed, while the eyepiece lens is positioned at the top of the microscope where the user looks through.

To attach these lenses properly, you will need to follow these steps:

1. Prepare the microscope: Place the microscope on a stable surface and ensure that it is clean and free from dust or debris.

2. Identify the objective lens: Look for the lens with multiple magnification options, usually marked with numbers such as 4x, 10x, 40x, or 100x. This lens is located on a rotating nosepiece near the bottom of the microscope.

3. Align the objective lens: Rotate the nosepiece so that the lowest magnification lens (e.g., 4x) is directly above the specimen stage. This lens should click or lock into place when properly aligned.

4. Secure the objective lens: Once the correct lens is aligned, gently tighten any locking mechanism on the nosepiece to ensure that the objective lens is securely attached and will not move during use.

5. Locate the eyepiece lens: The eyepiece lens is usually located at the top of the microscope, where you place your eye to observe the specimen. It is often removable or adjustable to accommodate different users.

6. Insert the eyepiece lens: If the eyepiece lens is not already inserted, carefully align it with the eyepiece tube and slide it into place. Make sure it fits securely and does not wobble or move when in position.

7. Adjust the eyepiece lens: Some eyepiece lenses have a focusing ring or diopter adjustment to accommodate individual differences in eyesight. If necessary, rotate the focusing ring until you achieve a clear, focused view.

By following these steps, you can correctly attach the objective lens and eyepiece lens on a compound microscope, allowing for proper magnification and observation of the specimen.

Here is a step-by-step guide on how to attach the two lenses on a compound microscope:

1. Start by locating the objective lenses on your compound microscope. These lenses are usually located on a rotating turret or nosepiece, which is located below the eyepiece.

2. Identify the two objective lenses that you want to attach. Compound microscopes usually come with multiple lenses of different magnifications, typically labeled with numbers such as 4x, 10x, 40x, and 100x.

3. Carefully grasp the microscope by its base or arm to ensure stability and prevent any damage.

4. Locate the first objective lens, usually the lowest power lens, and align its threaded portion with the opening on the rotating turret.

5. Insert the lens into the opening and gently twist it clockwise until it is securely attached. Be cautious not to apply excessive force, as it may cause damage.

6. Once the first lens is attached, locate the second objective lens that you want to use.

7. Align the threaded portion of the second lens with the opening on the rotating turret, making sure to align it correctly with the first lens.

8. Insert the second lens into the opening and gently twist it clockwise until it is securely attached.

9. Double-check that both lenses are securely attached by gently wiggling them. They should not move or come loose.

10. Once both lenses are attached, you can rotate the turret to switch between them, selecting the desired magnification level for your observation.

Remember to handle the lenses with care and avoid touching the actual glass surfaces to prevent smudges or damage. Additionally, consult your microscope's manual for specific instructions or guidelines provided by the manufacturer.
