Seeing how already referred to, in a glass case, where other specimens of animals and birds were well arranged and kept, the whole having been preserved by my tenant, Mr. William Phillips, who is well known in that part of the world as a keen sportsman and good naturalist. On noticing at once the peculiarities of the little animal, I asked Mr. Phillips how and where it was found, when to my great surprise, as well as increasing interest, he told me, as well as I can now recollect, the following story of its discovery :-

“He said, that one morning, in the year 1856 or '7, I can hardly now say for certain which, as he was walking in his farm-yard at Over.Norton, his attention was attracted by the sight of, as he at first thought, a lizard, lying in the gutter, evidently but

Upon, however, taking it up, he soon much interest I took in the affair, Mr. Phillips prediscovered that the animal was not a lizard, and he sented the little animal to me to bring to London, immediately asked his labourers, who were close by, as I told him I should be able, through some of my unstacking some faggots for the use of the house, if friends in town, to find out more about it. My they knew anything about it. The answer was that friend in reply remarked that it had already been to they had killed it as it ran out of the stack of London, and been shown at the British Museum, wood, I think the day before; and on Mr. Phillips but to whom he could not say; and that the opinion expressing his regret at their having done so without he had received of it was to the effect that it was a bringing it to him alive, they replied they could young crocodile, and had very likely been dropped in easily get him another, as at the place where the a rain shower, or perhaps had escaped from some wood was cut, a few miles from the farm, near to travelling menagerie.

“ The result of my inquiry was that Dr. Pettigrew pronounced the reptile a young crocodile, with a mother and father, as he laughingly remarked, as long as the hearthrug in his room, or even longer, but how it had been found and killed in this country, he could not venture an opinion upon. At his request I left the young reptile with him, to show to his friend Mr. Frank Buckland, who afterwards not only confirmed Dr. Pettigrew's views as to the character of the reptile, but subsequently, in a description of it in the Field newspaper, narrated

I have never used anything else since, except in mounting diatoms, when I use the ordinary balsam; my reason for so doing I will explain further on. I will now return to the balsam and chloroform.

I first dry the balsam until it becomes quite hard, and a ready (way of doing this is to pour it into a large pomade pot, the larger the area the quicker will be the process of hardening. I then place it in the kitchen oven after the fire has gone out, care being taken that the temperature is not too high, or the balsam will be discoloured. This operation must be repeated for five or six nights, when it will (with a layer of about an eighth of an inch deep) become quite hard, so that it may be chipped out with a knife.
