Hancock; because their opinions may safely be considered as unimpeachable authority on this subject, viz. the uses and medical virtues of _pure honey_. In some observations on the effect of the temperature of Bee-hives on the quality of honey, published in a scientific journal, Mr. Booth observes--"notwithstanding the adequate justice which has been done to Mr. Nutt's improved and admirable system of Bee-management, there is one point which does not appear to have elicited much attention--the superiority in quality both of the honey and the wax. It does not appear to me that the whole of this superiority consists in freedom from extraneous animal or vegetable matters, a point of very great importance, however, as its dietetic purposes are concerned; but that it greatly depends upon the modified degree of temperature at which the Bees effect their labours, and which is insufficient to produce any chemical changes in the constitution of these substances; whereas under the old system, the continued high temperature of the hive is sufficient to induce those changes which impart the colour that so materially deteriorates the quality as well as the value of the products. _From Mr. Nutt's hives we obtain pure honey, as it is actually secreted by the Bee_, which cannot be ensured by any other mode of management." To my very intelligent friend and patron, Dr. Birkbeck, whose uniform liberality and kindness, from the infancy of my pursuits, I have reason to appreciate, I am indebted for introducing this subject in a Lecture[A] at the London Institution, Moorfields, on the application of the oxy-hydrogen light to illustrate the economy and structure of the insect world. In the course of his observations, on referring to the tongue of the Bee, the learned Doctor made copious allusions to my system, and the advantages which would in his view result from its general extension. He observed that "so small is the supply that we derive from the labours of Bees in this country, that the production of wax does not even more than equal its consumption in the simple article of lip-salve. Under this improved system, we may however hope that the advantages of Bee-management may be more generally diffused throughout the kingdom,--that Bee-hives will be multiplied, and that the choicest flowers of the field and forest will no longer 'waste their sweetness in the desert air.' In a dietetic point of view, it is of great importance that a saccharine, secreted by one of the most beautiful processes of nature, should be substituted for one produced by the most imperfect and complicated process of art, whilst the more salutary properties of the former would recommend it as far more eligible for use. He could not but hope that, in this view the system would soon receive that extension in practice to which its merits fitted it."[B] [Footnote A: Delivered April 23d 1334.]
