To solve the question "Which of the following glands do not have ducts?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Glands**:
- Glands in the body are classified into two main types: exocrine glands and endocrine glands.

2. **Understand Exocrine Glands**:
- Exocrine glands are those that have ducts. They secrete their products (like enzymes, saliva, etc.) into these ducts, which then transport the secretions to specific sites. Examples include salivary glands, mammary glands, and intestinal glands.

3. **Understand Endocrine Glands**:
- Endocrine glands are ductless. They release their hormones directly into the bloodstream. Examples include the thyroid gland, adrenal gland, and pituitary gland.

4. **Analyze the Given Options**:

1. Salivary gland (exocrine, has ducts)
2. Mammary gland (exocrine, has ducts)
3. Intestinal gland (exocrine, has ducts)
4. Adrenal gland (endocrine, ductless)

5. **Determine the Correct Answer**:
- Among the options, the adrenal gland is the only one that does not have ducts, as it is an endocrine gland.
