The completion of Series 2, was greatly delayed by 

 reason of prolonged and serious illness combined with 

 unusual press of business in other branches of work. 

 For the future, arrangements have been made such as 

 will result in a punctual issue of the Series.

 separate publication, and will be the organ of the Jersey 

 Biological Station. It will be issued half-yearly. 



Practical Suggestions.

Manipulation of Soft Tissues. — It is very easy to 

 obtain thin sections of soft tissues such as the tissues of 

 fruits, trichinous pork, flesh and similar structures. 

 Cut a very small piece as thin as possible with a thin 

 knife. A microscopic dissecting knife is just the thing. 

 Then place the small piece on a glass slip under a number 

 two or number three cover and press down until the 

 section is flattened out thin. Success may nearly always 

 be attained by taking a very small piece. Failure will 

 usually follow by taking too large a particle. In this 

 way the cells and grit in a pear and the trichina in pork 

 may be quickly and elegantly seen. 



Blood Manipulation. — An old Doctor once called 

 upon the wife of a microscopist, during the latter'a 

 absence, and requested the wife to get out the microscope 

 to enable the doctor to examine his own blood. The 

 Doctor lanced himself, drew nearly a teaspoonful of blood, 

 daubed a nice, clean slide therewith, covered, examined 

 with the microscope and saw nothing but darkness
