paper of documents, &c. Microscopical appearances have also been suggested 

 as the basis of ornamental designs, as, for example, the appearances, noted 

 under the microscope, of chemical crystals, mentioned in the ' ' Scientiiic 

 American" in connection with designs for wall-papers, dados, &c. In the 

 study of microscopy a knowledge of drawing and the practice of photo- 

 micrography can be of much service, and excellent progress in the latter 

 art has been made of late years, but further developments should be sought 

 for, especially in connection with observations with high power objectives. 



As the microscope is of so much value for practical purposes, it should be 

 studied more than it is in science schools and in connection vdtb. trades and 

 industrial occupations. Even in ordinaiy school teaching it might be made 

 available for exciting greater interest in the lessons than is often given now, 

 and in giving a training in habits of thorough and careful investigation; 

 but in trade and technical schools a training in its use should form an 

 important part of the curriculum. In many such schools on the continent, 

 practice with the microscope is insisted on, and the value of such study has 

 been testified to, not only by the professors under whose auspices the 

 instruction has been given, but by a large number of manufacturers and 

 others in whose service the students have subsequently worked. 



In short, the practical applications of the microscope are so many and so 

 varied, that a more extended study of microscopy cannot fail to be 

 productive of great advantages, not only in scientific research, but also to 

 manufactures and commerce, and the health and comfort of the community. 



The lecture was illustrated by many diagrams shown by Mr. Knott with 

 the oxy-hydrogen lantern. A vote of thanks to the President for his 

 address concluded the proceedings. 



February 3rd. — Dr. Frederick C. Larkin, M.K.C.S, read a paper "On 

 Making Permanent Microscopical Specimens of Blood," in which he 

 described in detail the methods most suitable for mounting specimens of 

 the blood of different animals. In the short discussion which followed, 

 Mr. Edward Davies, F.I.C. and the President spoke of the practical 

 difficulty often experienced in medico-legal inquiries in detecting with 

 certainty the nature of blood found in bloodstains, &c. and Messrs. W. 

 NARR.-i^MORE and Kendal detailed special methods they had employed in 

 preparing blood specimens. Mr. Willotjghbt Gardner then read an 

 interesting paper on "Wing Scales of Butterflies," in which he described 

 the many beautiful forms and colours of the scales, and the usual modes of 

 arrangement, and illustrated his remarks with many drawings and a 

 collection of butterflies.
