| This burner may be made of any size, and for consumptions not exceeding that of an ordinary Argand. |
| On the table are an English mahogany and satinwood tea caddy of about 1805 and an argand lamp of 1830 to 1835 labeled by Thomas Messenger and Sons of London and Birmingham. |
| These mirrors could increase the intensity of an Argand burner, nominally about five candlepower, almost 400 times. |
| The Argand lamps in the dining room and parlor are especially interesting. |
| The concept of the modulus of a complex number is also due to Argand but Cauchy, who used the term later, is usually credited as the originator this concept. |
| The Argand lamp of 1812 was not at all powerful and the lenses used were far from perfect. |
