General Botany covers certain aspects of general botany, such as morphology, anatomy, and histology. The book discusses the molecular constitution of plants; the structural constitution of the protoplasm, the cell, and the cytoplasm; and the differentiation of the cell. The text also describes the types of organization in plants; the internal and external structure of the stem, the leaf, and the root; and water and salt balance, with regard to the translocation of materials. The energy procurement and the synthetic processes in autotrophic plants; the respiration and energy transformations; and nitrogen metabolism are also considered. The book further tackles heterotrophy; reproduction; heredity; development; and the movement of plants. Botanists, cytologists, plant physiologists, and students taking related courses will find the text invaluable.
PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...
The laboratory component of General Botany provides you the opportunity to view interrelationships between and among structures, to handle live or preserved material, to become familiar with the many terms we use throughout the course, and to learn how to use a microscope properly. Each of you will have your own microscope every week, no exceptions. This laboratory is fundamental, yet integral to your understanding of General Botany. The images in your manual are intended to serve as a guide while you view permanent or prepared slides. These must be viewed by each of you independently. At no time will questions be answered re where is a particular structure, etc., unless the slide is on the stage of your microscope and in focus.The content of the laboratory is rich, as is the terminology. You must come to lab prepared. You must come to lab knowing what the various terms you are about to deal with mean. There is no such thing as finishing early that simply isn't possible.In some laboratory exercises you will be asked to identify structures of an organism. For example, Examine slide 9 labeled Rhizopus sporangia w.m. and identify the mitosporangia, mitospores, columella, mitosporangiophore, and zygotes. In all likelihood you will only be able to see mitosporangia, mitospores, columella, and mitosporangiophores. If zygotes are absent in your slide you note that the population of hyphae you are examining are only reproducing asexually. These questions are written in this manner to further fortify your understanding of the organisms in question and not to trick you. Thinking about what you are viewing is not an option but a necessity!The phylogeny we have adopted in this course is a composite. No single phylogeny best reflects our collective understanding of all the organisms included in this course so we have created one that reflects modern thought and is based on both morphological and molecular data. None is any more correct or incorrect than is any other, but this is the one that we will use, and the one we deem as most acceptable.Rest assured, much still needs to be learned about the evolution of many of the groups we will study. Regardless, the course does provide you a general overview of the evolutionary biology of these various groups. This is your starting point, it is not the endpoint!
