    CHAPTER VIII. CULTIVATIONS OF THE VARIOUS MORBID PRODUCTS OP THE DISEASES. Having now given an account of our investigations Account of cuitiva- into the naturc of the changes and tions of morbid pro- , ,. i i j.i t ducts. degenerations caused by the disease and the characters of their morbid products, we shall next state briefly the results of our attempts at cultiva- tions of these products. In doing this, we shall in some degree depart from the order which we have hitherto followed in the consideration of the different forms of the disease; for it appears advisable to consider those cultivations in which the material experimented with contained distinct fungoid elements, before those in which there was no evidence of the presence of any such bodies. In undertaking cultivation-experiments of this cha- A new growine-ceu ractcr, the principal difficulty usually a^'ai^Vp^^^^^ consists, not in selection of ingredi- ents favourable to the growth of the object under observation, but in the isolation of the lat- ter. To follow the growth of a single spore or a speck of plasma may seem a very simple matter to such as have never undertaken such an experiment, but the task is in reality very difficult if the germ experimented upon be given a fair chance of growth—at least as far as light, heat, air, and moisture are concerned. The appliance which we have devised, and for some time adopted, to meet this diflBculty, is very simple, and may be constructed by any one desirous of working out for themselves problems of this character.
