"But I have not shown by what artifice this past time (ibam) of _eo_ is formed. It is, we may see, composed of two words, _ib_ and _am_; yet the latter word _am_ has all the appearance of a present time or a future; as we may see it in e_am_, leg_am_, and audi_am_. Then it is evidently to the word _ib_ we are indebted for this word _ibam_ having a past signification; and as there is now no such Latin word, we are led to believe that _ib_ must be a contraction, and this at once leads us upon _ibi_, which means, _then_, or, _at that time_. Hence, _ibam_ is a contraction of _ibi am_, there being only the letter _i_ omitted. Now, as _am_ is evidently a present time, and the same _am_ we have in English, it means, "I existence;" so that when _ibi_ is added to it, both words mean, "I existence then," or "at that time;" and it is in this manner that men, in the beginning, made a past time. If we now turn to the past time of _sum_ (_eram_, _eras_, _erat_, &c.) we shall find that the same method has been adhered to. The _am_ here is the _am_ in ib_am_; and now we have to look to the word _er_ by which it is preceded, in order to find its past signification. This brings us to _era_, or as it is now written in Latin, _aera_ which, like _ibi_, refers also to a past time, meaning _that epoch_. Then _eram_, which might as well be written _aeram_, is a contraction of aer_a_am, there being, as before, but a single letter omitted, (the _a_,) and the meaning is as before, "I existence _then_, or _at that epoch_." Certainly if ever there was a man who "existenced" at an era or epoch, or rather who was himself the era, Mr Kavanagh may claim the distinction. We are informed by the printer that our space is nearly out, and we must therefore draw to a close. We cannot better fill up the limits allowed us, than by selecting a few examples of our author's successful treatment of etymology. It will be seen that in the zoological department of this subject he is particularly happy.
