So far our course had been before the wind. Every new formality had but increased our importance in the eyes of our fair visiters and their respectable companions. Mr. Catherwood retired to the adjoining room to put the plate in the mercury bath, while we, not knowing what the result might be, a little fearful, and neither wishing to rob another of the honour he might be justly entitled to, not to be dragged down by another's failure, thought best to have it distinctly understood that Mr. Catherwood was the maestro, and that we were merely amateurs. At the same time, on Mr. Catherwood's account, I took occasion to suggest that the process was so complicated, and its success depended upon such a variety of minute circumstances, it seemed really wonderful that it ever turned out well. The plate might not be good, or not well cleaned; or the chemicals might not be of the best; or the plate might be left too long in the iodine box, or taken out too soon; or left too long in the bromine box, or taken out too soon; or a ray of light might strike it on putting it into the camera or in taking it out; or it might be left too long in the camera or taken out too soon; or too long in the mercury bath or taken out too soon; and even though all these processes were right and regular, there might be some other fault of omission or commission which we were not aware of; besides which, climate and atmosphere had great influence, and might render all of no avail. These little suggestions we considered necessary to prevent too great a disappointment in case of failure; and perhaps our fair visiters were somewhat surprised at our audacity in undertaking at all such a doubtful experiment, and using them as instruments. The result, however, was enough to induce us never again to adopt prudential measures, for the young lady's image was stamped upon the plate, and made a picture which enchanted her and satisfied the critical judgment of her friends and admirers.

Our experiments upon the other ladies were equally successful, and the morning glided away in this pleasant occupation.

We continued practising a few days longer; and as all our good results were extensively shown, and the poor ones we took care to keep out of sight, our reputation increased, and we had abundance of applications.

In this state of things we requested some friends to whom we were under many obligations, to be permitted to wait upon them at their houses. On receiving their assent, the next morning at nine o'clock Mr. C. in a caleza, with all the complicated apparatus packed around him, drove up to their door. I followed on foot. It was our intention to go through the whole family, uncles, aunts, grandchildren, down to Indian servants, as many as would sit; but man is born to disappointment. I spare the reader the recital of our misfortunes that day. It would be too distressing. Suffice it to say that we tried plate after plate, sitting after sitting, varying light, time, and other points of the process; but it was all in vain. The stubborn instrument seemed bent upon confounding us; and, covering our confusion as well as we could, we gathered up our Daguerreotype and carried ourselves off. What was the cause of our complete discomfiture we never ascertained, but we resolved to give up business as ladies' Daguerreotype portrait takers.

There was one interesting incident connected with our short career of practice. Among the portraits put forth was one of a lady, which came to the knowledge of a gentleman particularly interested in the fair original. This gentleman had never taken any especial notice of us before, but now he called upon us, and very naturally the conversation turned upon that art of which we were then professors. The portrait of this lady was mentioned, and by the time he had finished his third straw cigar, he unburdened himself of the special object of his visit, which was to procure a portrait of her for himself. This seemed natural enough, and we assented, provided he would get her to sit; but he did not wish either her or her friends to know anything about it. This was a difficulty. It was not very easy to take it by stealth. However strong an impression a young lady may make by a glance upon some substances, she can do nothing upon a silver plate. Here she requires the aid of iodine, bromine, and mercury. But the young man was fertile in expedients. He said that we could easily make some excuse, promising her something more perfect, and in making two or three impressions, could slip one away for him. This was by no means a bad suggestion, at least so far as he was concerned, but we had some qualms of conscience. While we were deliberating, a matter was introduced which perhaps lay as near Doctor Cabot's heart as the young lady did that of our friend. That was a pointer or setter dog for hunting, of which the doctor was in great want. The gentleman said he had one-the only one in Merida—and he would give it for the portrait. It was rather an odd proposition, but to offer a dog for his mistress's portrait was very different from offering his mistress's portrait for a dog. It was clear that the young man was in a bad way; he would lay down his life, give up smoking, part with his dog, or commit any other extravagance. The case was touching. The doctor was really interested; and, after all, what harm could it do? The doctor and I went to look at the dog, but it turned out to be a mere pup, entirely unbroken, and what the result might have been I do not know, but all farther negotiations were broken off by the result of our out-of-door practice and disgust for the business.

There is no immediate connexion between taking Daguerreotype portraits and the practice of surgery, but circumstances bring close together things entirely dissimilar in themselves, and we went from one to the other. Secluded as Merida is, and seldom visited by strangers, the fame of new discoveries in science is slow in reaching it, and the new operation of Mons. Guerin for the cure of strabismus had not been heard of. In private intercourse we had spoken of this operation, and, in order to make it known, and extend its benefits, Doctor Cabot had offered to perform it in Merida. The Merida people have generally fine eyes, but, either because our attention was particularly directed to it, or that it is really the case, there seemed to be more squinting eyes, or biscos, as they are called, than are usually seen in any one town, and in Merida, as in some other places, this is not esteemed a beauty; but, either from want of confidence in a stranger, or a cheap estimation of the qualifications of a medico who asked no pay for his services, the doctor's philanthropic purposes were not appreciated. At least, no one cared to be the first; and as the doctor had no sample of his skill with him, no subject offered.

We had fixed the day for our departure; and the evening but one before, a direct overture was made to the doctor to perform the operation. The subject was a boy, and the application in his behalf was made by a gentleman who formed one of a circle in which we were in the habit of visiting, and whom we were all happy to have it in our power to serve.

The time was fixed at ten o'clock the next day. After breakfast our sala was put in order for the reception of company, and the doctor for the first time looked to his instruments. He had some misgivings. They were of very fine workmanship, made in Paris, most sensitive to the influence of the atmosphere, and in that climate it was almost impossible to preserve anything metallic from rust. The doctor had packed the case among his clothing in the middle of his trunk, and had taken every possible precaution, but, as usual upon such occasions, the most important instrument had rusted at the point, and in that state was utterly useless. There was no cutler in the place, nor any other person competent to touch it. Mr. Catherwood, however, brought out an old razor hone, and between them they worked off the rust.

At ten o'clock the doctor's subject made his appearance. He was the son of a widow lady of very respectable family, about fourteen years old, but small of stature, and presenting even to the most casual glance the stamp of a little gentleman. He had large black eyes, but, unluckily, their expression was very much injured by an inward squint. With the light heart of boyhood, however, he seemed indifferent to his personal appearance, and came, as he said, because his mother told him to do so. His handsome person, and modest and engaging manners, gave us immediately a strong interest in his favour. He was accompanied by the gentleman who had spoken of bringing him, Dr. Bado, a Guatimalian educated in Paris, the oldest and principal physician of Merida, and by several friends of the family, whom we did not know.

Preparations were commenced immediately. The first movement was to bring out a long table near the window; then to spread upon it a mattress and pillow, and upon these to spread the boy. Until the actual moment of operating, the precise character of this new business had not presented itself to my mind, and altogether it opened by no means so favourably as Daguerreotype practice.
