Lest I should be suspected to misunderstand his meaning, I shall give it in his own words. Speaking of the opercula or covering to the gills of the mud inguana, he proceeds to say that 'The forms of these pennated coverings approach very near to what I have some time ago observed in the larva or aquatic state of our English lacerta, known by the name of eft, or newt; which serve them for coverings to their gills, and for fins to swim with while in this state; and which they lose, as well as the fins of their tails, when they change their state, and become land animals, as I have observed, by keeping them alive for some time myself:'

Providence has been so indulgent to us as to allow of but one venomous reptile of the serpent kind in these kingdoms, and that is the viper. As you propose the good of mankind to be an object of your publications, you will not omit to mention common salad-oil as a sovereign remedy against the bite of the viper.

Though they are oviparous, yet they are viviparous also, hatching their young within their bellies, and then bringing them forth. Whereas snakes lay chains
